Nuclear oncology uses radioactive tracers to both diagnose and treat cancer, bridging the gap between imaging and targeted therapy in one specialty.

Different PET CT tracers target different cancers. Understanding which scan fits which clinical question helps doctors decide.

A gastric emptying study uses a radioactive-labelled meal to measure how fast your stomach empties, helping diagnose gastroparesis.

FAPI PET CT is changing how certain cancers are diagnosed in Bangalore (Bengaluru). While FDG remains the workhorse tracer for PET CT imaging, FAPI offers clear advantages for cancers that FDG struggles to detect. This guide covers what FAPI PET CT is, when it is recommended over FDG, which cancers respond best to FAPI imaging, and where to get a FAPI PET CT scan in Bangalore. What Is FAPI? FAPI stands for Fibroblast Activation Protein Inhibitor. FAP is a protein that appears on cancer-associated fibroblasts, the connective tissue cells that surround and support tumours. Almost all solid cancers produce these activated fibroblasts, making FAPI a broadly applicable tracer. When labelled with Gallium-68 (Ga-68 FAPI), it becomes a PET CT tracer that lights up wherever FAP is overexpressed. This is fundamentally different from FDG, which targets glucose metabolism. FAPI vs FDG: Head-to-Head Comparison Feature FDG PET CT FAPI PET CT What it targets Glucose metabolism Fibroblast activation protein Fasting required Yes (4-6 hours) No Safe for diabetics Blood sugar must be controlled No blood sugar issues Brain tumour imaging Limited (high normal brain uptake) Excellent (low brain background) Liver tumour detection Moderate (liver has FDG uptake) Superior (very low liver background) Scan timing after injection 60 minutes wait 10 minutes wait Inflammation false positives Common Much less common Peritoneal carcinomatosis Often missed Much better detection When Your Doctor Should Consider FAPI Instead of FDG FAPI PET CT is not meant to replace FDG for every patient. It is most valuable in specific clinical scenarios where FDG has known limitations. Pancreatic Cancer Pancreatic adenocarcinoma is surrounded by dense fibrous tissue (desmoplastic stroma) that is rich in FAP. FAPI PET CT detects pancreatic cancers with higher sensitivity than FDG and is particularly useful for identifying small peritoneal metastases that FDG misses. Brain Tumours The normal brain consumes large amounts of glucose, creating high background activity on FDG PET CT. This makes it difficult to distinguish brain tumours from normal tissue. FAPI has minimal normal brain uptake, providing much clearer tumour visualisation. Liver Cancers Similar to the brain, the liver has significant baseline FDG uptake. Hepatocellular carcinoma and liver metastases can be difficult to see on FDG scans. FAPI has very low liver background activity, making liver lesions stand out clearly. Gastric and Oesophageal Cancer FAPI PET CT has shown superior detection of peritoneal metastases in gastric cancer, which directly impacts whether surgery is appropriate. Sarcomas Soft tissue sarcomas often have strong FAPI uptake due to their stromal composition. FAPI PET CT can be valuable for staging and treatment response assessment in sarcoma patients. Post-Treatment Assessment After surgery, radiation, or chemotherapy, inflammation at the treatment site can cause false-positive results on FDG PET CT. FAPI is less affected by inflammation, making it more reliable for early post-treatment scanning. FAPI PET CT for Radioligand Therapy Selection FAPI is not just a diagnostic tool. When a FAPI PET CT scan shows strong tracer uptake in a tumour, it indicates that the same target can potentially be used for therapy. Lu-177 FAPI therapy uses the same molecular target to deliver radiation directly to the tumour. This is the theranostics approach: use FAPI PET CT to see the target, then use Lu-177 FAPI to treat it. Dr. Prathap H.J. in Bangalore offers both the diagnostic FAPI PET CT scan and the therapeutic Lu-177 FAPI treatment. Cancers Where FAPI PET CT Has Shown Benefit Pancreatic adenocarcinoma Cholangiocarcinoma (bile duct cancer) Gastric and gastro-oesophageal junction cancers Colorectal cancer with peritoneal involvement Breast cancer (particularly lobular breast cancer) Sarcomas (soft tissue and bone) Head and neck cancers Brain tumours (gliomas, meningiomas) Hepatocellular carcinoma Ovarian cancer with peritoneal spread Thyroid cancer (when FDG is negative) FAPI PET CT Scan in Bangalore: What to Expect The FAPI PET CT experience is simpler than FDG for patients: No fasting required. Eat and drink normally. No blood sugar checks needed. Tracer is injected intravenously. Scanning begins just 10 minutes after injection (vs 60 minutes for FDG). The scan itself takes 20 to 30 minutes. Total visit time is approximately 1 to 1.5 hours (shorter than FDG). FAPI PET CT scan in Bangalore is available at select nuclear medicine centres. Not all PET CT centres stock FAPI tracer, so confirm availability when booking. Frequently Asked Questions Is FAPI PET CT better than FDG PET CT? FAPI is not universally better than FDG. For most common cancers (lung, lymphoma, melanoma), FDG remains the preferred tracer. FAPI is superior for specific cancers where FDG has limitations, particularly pancreatic cancer, brain tumours, liver cancers, and peritoneal disease. Can FAPI PET CT replace FDG PET CT? Not entirely. Both tracers provide different biological information. In some cases, doctors may recommend both scans to get complementary data. However, for certain cancers, FAPI alone provides better diagnostic accuracy than FDG. Is FAPI PET CT scan available in Bengaluru? Yes. FAPI PET CT scan is available in Bangalore (Bengaluru) at select nuclear medicine centres. Dr. Prathap H.J. offers FAPI PET CT scans and can advise whether FAPI is appropriate for your specific cancer type. How much does a FAPI PET CT scan cost in Bangalore? Contact the nuclear medicine centre directly for current pricing. FAPI scans may have different pricing from standard FDG scans due to the specialised tracer involved.

If your doctor has recommended a PET CT scan in Bangalore (Bengaluru), you probably have questions about the process, preparation, and what happens after. This is a practical guide covering everything from booking to getting your results. Step 1: Getting a Referral A PET CT scan is a specialised investigation. Your oncologist, surgeon, or treating physician will write a referral specifying which type of PET CT scan you need and why. The referral typically includes your diagnosis or suspected condition, the clinical question the scan needs to answer, and any relevant previous imaging or biopsy results. Bring this referral when you visit the nuclear medicine centre. It helps the reporting physician tailor the scan protocol and interpretation to your specific situation. Step 2: Booking Your Scan Call the nuclear medicine centre to schedule your appointment. When booking, mention: The type of PET CT scan your doctor requested (FDG, PSMA, FAPI, DOTANOC, etc.) Your cancer type and current treatment status Whether you are diabetic (important for FDG scans) Any previous PET CT scans (the centre may want comparison images) Dr. Prathap H.J. in Bangalore can be reached at +91 80505 97975 for PET CT scan bookings. Step 3: Preparing for the Scan For FDG PET CT (the most common type) Fast for 4 to 6 hours before the scan. Water is allowed. Avoid strenuous exercise for 24 hours before the scan. If you are diabetic, discuss blood sugar management with the centre beforehand. Your blood sugar should ideally be below 200 mg/dL at the time of the scan. Continue your regular medications unless told otherwise. Wear comfortable, loose clothing without metal zippers or buttons. For PSMA, FAPI, and DOTANOC PET CT No fasting required for most non-FDG tracers. PSMA scans may require you to drink extra water and empty your bladder frequently. FAPI scans have the simplest preparation with no dietary restrictions. Step 4: The Day of Your Scan Arrival and Registration (15 minutes) Arrive at the centre on time. You will complete registration paperwork and provide your referral letter, previous scan reports, and any relevant blood work. Tracer Injection (5 to 10 minutes) A small amount of radioactive tracer is injected into a vein in your arm. The injection feels like a regular blood draw. The tracer itself causes no side effects. Uptake Period (45 to 60 minutes for FDG; 10 minutes for FAPI) After injection, you rest quietly in a comfortable room. During this time, the tracer distributes through your body and accumulates in target tissues. For FDG scans, you need to stay still and avoid talking, reading, or using your phone, as muscle activity can affect the scan. For FAPI scans, the uptake period is much shorter. The Scan Itself (20 to 30 minutes) You lie on a scanning table that moves slowly through a large, open ring (not a closed tunnel like MRI). The scan is painless and quiet. You need to lie still during the scan. Most patients find it comfortable. After the Scan You can resume normal activities immediately. Drink plenty of water to help flush the tracer from your body. The radioactivity is very low and disappears within a few hours. Step 5: Getting Your Results The nuclear medicine physician analyses hundreds of images from your scan, comparing PET and CT data across your entire body. A detailed report is typically ready within 24 to 48 hours. The report includes: Findings in each body region (head, neck, chest, abdomen, pelvis, skeleton) SUV values (standardised uptake values) for any abnormal areas Comparison with previous scans if available Clinical impression and recommendations Understanding SUV Values SUV (Standardised Uptake Value) is a number that quantifies how much tracer an area has absorbed. Higher SUV generally indicates more metabolic activity. SUV below 2.5 is often considered low and may represent benign processes SUV above 2.5 raises suspicion for malignancy, but context matters The absolute number is less important than the pattern and clinical context Your oncologist will interpret the SUV values in the context of your overall clinical picture. Do not try to self-diagnose based on SUV numbers alone. How Often Are PET CT Scans Repeated? During treatment: Interim scans may be done after 2 to 3 cycles of chemotherapy End of treatment: A scan 8 to 12 weeks after completing treatment Surveillance: Only when there is clinical suspicion of recurrence (rising markers, new symptoms) Routine surveillance PET CT scans without clinical indication are generally not recommended by international guidelines. Is a PET CT Scan Safe? Yes. The radiation dose from a single PET CT scan is approximately 10 to 25 mSv, which is comparable to other medical imaging procedures. For cancer patients, the diagnostic benefit of accurate staging and treatment monitoring far outweighs the minimal radiation risk. The radioactive tracer is not a dye or contrast agent. Allergic reactions are extremely rare. The tracer is excreted naturally through urine within a few hours. PET CT Scan in Bangalore: Practical Tips Plan for 2 to 3 hours at the centre (including preparation, uptake, and scanning) Bring a family member who can drive you home if you prefer not to drive Carry your previous scan CDs or reports for comparison If travelling from outside Bangalore, consider scheduling other appointments on the same trip Ask the centre for a soft copy of your report and images (most provide these digitally) Frequently Asked Questions Can I eat before a PET CT scan? For FDG PET CT scans, you must fast for 4 to 6 hours. For PSMA, FAPI, and DOTANOC scans, fasting is usually not required. The centre will provide specific instructions when you book. How long does a PET CT scan take in Bangalore? The entire visit takes 2 to 3 hours. The actual scan takes 20 to 30 minutes. The rest is preparation, tracer injection, and the uptake waiting period. Can I travel after a PET CT scan? Yes. You can travel immediately after the scan. There are no restrictions on driving, flying, or taking public transport. Will

Choosing the right PET CT scan centre in Bangalore (Bengaluru) is a decision that directly affects your diagnosis and treatment. Not all centres offer the same tracers, equipment, or expertise. This guide explains what to look for, the questions to ask, and what makes a PET CT centre genuinely different from others. Why the Centre Matters as Much as the Scan A PET CT scan is not like a routine blood test where results are fairly standardised across labs. The quality of a PET CT scan depends on the equipment used, the radiopharmacy preparing the tracer, the scanning protocol, and most critically, the nuclear medicine physician who interprets the images. Two centres scanning the same patient on the same day can produce different reports if the interpreting physician has different levels of experience or if the scan protocol differs. What to Look for in a PET CT Scan Centre 1. Range of Tracers Available Most PET CT centres in Bangalore offer FDG (fluorodeoxyglucose) scans. FDG covers the majority of cancer imaging needs. But certain cancers require specialised tracers that are only available at select centres. Ask whether the centre offers: FDG: The standard tracer for most cancers PSMA: For prostate cancer (much more sensitive than bone scans) FAPI: For cancers where FDG is less effective (pancreas, brain, liver) Ga-68 DOTANOC: For neuroendocrine tumours CXCR4: For blood cancers like multiple myeloma Exendin: For insulinomas A centre that offers only FDG may need to refer you elsewhere if your cancer requires a different tracer. Dr. Prathap H.J. in Bangalore offers all major PET CT tracers including newer options like FAPI, CXCR4, Exendin, CAIX, and GPC3. 2. Nuclear Medicine Physician Expertise The physician interpreting your PET CT scan should be a qualified nuclear medicine specialist, not a general radiologist reading PET CT scans on the side. Nuclear medicine is a distinct speciality with dedicated training in radiotracer physics, pharmacology, and image interpretation. 3. Theranostics Capability Theranostics is the approach where the same molecular target used for diagnosis (PET CT) is also used for treatment (radioligand therapy). If your PET CT scan shows targets that can be treated with radioligand therapy, it saves time and improves continuity if the same centre offers both. For example, a PSMA PET CT scan that shows PSMA-positive metastases means the patient may benefit from Lu-177 PSMA therapy. Having the diagnostic and therapeutic expertise under one roof streamlines the process. 4. Equipment Quality Modern PET CT scanners offer better resolution, faster scan times, and lower radiation doses than older models. Ask about the scanner model and when it was installed. 5. Report Turnaround Time In cancer care, time matters. Ask how quickly you will receive your report. Most good centres deliver reports within 24 to 48 hours. Some provide same-day preliminary results for urgent cases. 6. Location and Accessibility PET CT scans take 2 to 3 hours in total (including tracer injection, uptake waiting period, and the actual scan). Choose a centre that is reasonably accessible. Bangalore traffic can add significant travel time, so a centrally located centre reduces the overall burden on the patient. PET CT Scan Centres in Bangalore: What Sets This City Apart Bangalore is one of the leading cities in India for nuclear medicine. The city has multiple PET CT centres ranging from large hospital-based departments to standalone nuclear medicine practices. What distinguishes Bangalore from most cities is the availability of advanced tracers beyond FDG. Dr. Prathap H.J. is a nuclear medicine specialist in Bangalore who offers comprehensive PET CT imaging and radioligand therapy. His practice covers the full theranostics spectrum: from diagnostic PET CT scans using multiple tracers to therapeutic interventions like Lu-177 PSMA, Lu-177 DOTATATE, Lu-177 FAPI, and radioactive iodine therapy. Frequently Asked Questions Do I need a referral for a PET CT scan in Bangalore? Most PET CT centres prefer a referral from your treating oncologist or physician. The referral provides clinical context that helps the nuclear medicine physician choose the right tracer and protocol. How do I know which type of PET CT scan I need? Your oncologist will specify the scan type based on your cancer diagnosis. If you are unsure, the nuclear medicine centre can guide you based on your medical reports. See our guide on types of PET CT scans available in Bangalore. Can I get my PET CT scan done at one centre and show the report to my doctor at another hospital? Yes. PET CT reports and images (on CD or digital) are portable. Many patients get scanned at a specialised nuclear medicine centre and take the results to their treating oncologist at a different hospital. How far in advance should I book a PET CT scan? For FDG PET CT scans, most centres can accommodate bookings within 2 to 3 days. Specialised tracers like FAPI, CXCR4, or Exendin may require more advance notice as the tracer needs to be prepared specifically for your scan.

A PET CT scan is one of the most important tools in modern cancer care. From the moment a suspicious lump is found to years after treatment ends, PET CT imaging gives oncologists information that no other single test can provide. This guide explains how PET CT scans are used at every stage of a cancer journey, what the scan can and cannot tell you, and what to expect if you are getting one in Bangalore (Bengaluru). Why PET CT Is Central to Cancer Care Cancer cells behave differently from normal cells. They multiply faster, consume more energy, and express different proteins on their surface. PET CT scans exploit these differences. A radioactive tracer injected into your bloodstream accumulates preferentially in cancer cells, making them visible on the scan. The CT component provides a detailed anatomical map of your body. When combined, the PET and CT images show exactly where cancer is active and how extensive the disease is. PET CT for Initial Cancer Diagnosis When a biopsy confirms cancer, the first question is: has it spread? A PET CT scan answers this by surveying your entire body in one examination. What PET CT reveals at diagnosis The primary tumour location and metabolic activity Whether nearby lymph nodes are involved Whether the cancer has metastasised to distant organs Unexpected secondary primary cancers (found in about 1 to 2 percent of scans) This information directly determines your treatment plan. A cancer that appears localised on CT but shows distant metastases on PET CT will be treated very differently. PET CT for Cancer Staging Staging is the formal process of classifying how far cancer has spread. Most cancers use the TNM system: Tumour size (T), Node involvement (N), and Metastasis (M). PET CT is the most accurate single test for determining the N and M components. How PET CT changes staging Studies consistently show that PET CT changes the cancer stage in 15 to 40 percent of patients compared to conventional imaging alone. This means that without PET CT, a significant number of patients would receive treatment aimed at the wrong stage of disease. Cancers where PET CT staging is most valuable Lung cancer (both non-small cell and small cell) Lymphoma (Hodgkin and non-Hodgkin) Head and neck cancers Oesophageal cancer Colorectal cancer with suspected liver metastases Melanoma Cervical cancer For prostate cancer, PSMA PET CT has replaced conventional bone scans and CT scans as the most accurate staging tool. PET CT During Cancer Treatment One of the most valuable uses of PET CT is checking whether your treatment is working. This is called interim or mid-treatment PET CT. How treatment response is measured Nuclear medicine physicians compare the metabolic activity (measured as SUV, or Standardised Uptake Value) between your baseline scan and the interim scan. A significant drop in SUV means the cancer is responding to treatment. Complete metabolic response: No abnormal tracer uptake visible. The cancer appears to be gone on imaging. Partial metabolic response: SUV has decreased significantly but some activity remains. Stable metabolic disease: No significant change. The treatment is not shrinking the cancer but not letting it grow either. Progressive metabolic disease: New areas of uptake or increased SUV. The cancer is growing despite treatment. In lymphoma, interim PET CT after 2 cycles of chemotherapy (using the Deauville scoring system) is now standard practice and directly influences whether treatment is escalated or de-escalated. PET CT After Cancer Treatment After completing chemotherapy, radiation, or surgery, an end-of-treatment PET CT scan confirms whether treatment achieved its goal. This scan is typically done 8 to 12 weeks after the last treatment cycle to allow inflammation to settle. PET CT for Detecting Cancer Recurrence Cancer can return months or years after successful treatment. Rising tumour markers (like PSA for prostate cancer or CEA for colorectal cancer) may be the first sign, but conventional imaging often cannot locate the recurrence when marker levels are low. PET CT can detect recurrent disease at lower tumour burdens than CT or MRI alone. For prostate cancer recurrence, PSMA PET CT in Bangalore can detect disease even when PSA levels are below 0.5 ng/mL. Which PET CT Tracer Is Used for Which Cancer? Cancer Type Recommended PET CT Tracer Why This Tracer Lung cancer FDG High glucose metabolism in lung tumours Lymphoma FDG Standard for staging and response assessment Breast cancer FDG Staging and recurrence detection Prostate cancer PSMA Targets prostate-specific membrane antigen Neuroendocrine tumours Ga-68 DOTANOC Targets somatostatin receptors on NET cells Pancreatic cancer FAPI Better than FDG for pancreatic lesions Brain tumours FAPI Normal brain has high FDG uptake, FAPI avoids this Liver cancer (HCC) GPC3 Targets glypican-3 on liver cancer cells Kidney cancer (clear cell) CAIX Targets carbonic anhydrase IX Blood cancers (myeloma) CXCR4 Targets CXCR4 chemokine receptor Dr. Prathap H.J. offers all these PET CT tracers at his nuclear medicine practice in Bangalore. Cancers Where PET CT Is Most Useful Lung Cancer PET CT is considered essential for lung cancer staging. It detects mediastinal lymph node involvement and distant metastases that change treatment from surgery to systemic therapy. International guidelines recommend PET CT for all patients with non-small cell lung cancer being considered for curative treatment. Lymphoma Lymphoma and PET CT are closely linked. FDG PET CT is used at diagnosis for staging, after 2 cycles for interim response, and at end of treatment. The Lugano classification for lymphoma staging requires PET CT. Head and Neck Cancers PET CT is particularly valuable for finding the primary tumour when a patient presents with a cancerous lymph node in the neck but no obvious primary site (cancer of unknown primary). Prostate Cancer PSMA PET CT has changed prostate cancer management significantly. It detects disease at PSA levels where conventional imaging shows nothing, allowing earlier and more targeted intervention. Limitations of PET CT in Cancer PET CT is powerful but not perfect. Understanding its limitations helps set realistic expectations. Small tumours (under 7 to 8 mm) may not be detected Some cancers are not FDG-avid

Bangalore has become one of the leading cities in India for advanced nuclear medicine imaging. Patients across Karnataka and South India travel here specifically for PET CT scans that are not available at most diagnostic centres. This guide covers every type of PET CT scan available in Bangalore (Bengaluru), what each one detects, and which scan your oncologist might recommend based on your condition. What Is a PET CT Scan? A PET CT scan combines two imaging technologies into one examination. The PET (Positron Emission Tomography) component uses a small amount of radioactive tracer injected into your bloodstream. Cancer cells absorb this tracer at higher rates than normal tissue. The CT (Computed Tomography) component provides detailed anatomical images. Together, they show both where abnormal activity is happening and its exact location in your body. Different tracers target different biological processes. This is what makes the various types of PET CT scans distinct from each other. FDG PET CT Scan FDG (fluorodeoxyglucose) is the most widely used tracer in PET CT imaging worldwide. It works by mimicking glucose. Cancer cells consume glucose at much higher rates than normal cells, so FDG accumulates in tumours and lights up on the scan. When FDG PET CT is recommended Initial cancer diagnosis and staging Lymphoma, lung cancer, breast cancer, colorectal cancer, head and neck cancers Monitoring treatment response during chemotherapy or radiation Detecting cancer recurrence after treatment Evaluating solitary pulmonary nodules Certain infections and inflammatory conditions FDG PET CT is available at multiple centres in Bangalore. Dr. Prathap H.J., a nuclear medicine specialist practising in Bangalore, performs FDG PET CT scans regularly for patients referred by oncologists across the city. Read more about FDG PET CT scans FAPI PET CT Scan FAPI (Fibroblast Activation Protein Inhibitor) PET CT is one of the newer tracers gaining traction in Bangalore. Unlike FDG, which targets glucose metabolism, FAPI targets a protein called FAP that is overexpressed in the connective tissue (stroma) surrounding many cancers. Advantages of FAPI over FDG No fasting required before the scan Safe for diabetic patients without blood sugar concerns Better imaging of brain tumours (FDG has high normal brain uptake) Better liver tumour detection (lower background liver activity) Clearer images in areas where inflammation mimics cancer on FDG Scan can be done within 10 minutes after injection Cancers where FAPI PET CT is useful Pancreatic cancer, cholangiocarcinoma (bile duct cancer), gastric cancer, peritoneal carcinomatosis, sarcomas, certain breast cancers, and brain tumours. FAPI PET CT scan in Bangalore is available at select nuclear medicine centres. Learn more about FAPI PET CT in Bangalore PSMA PET CT Scan PSMA (Prostate Specific Membrane Antigen) PET CT has transformed how prostate cancer is detected and staged. PSMA is a protein found on the surface of prostate cancer cells, and this scan targets it directly. When PSMA PET CT is used Initial staging of high-risk prostate cancer before surgery or radiation Detecting recurrence when PSA levels rise after treatment Identifying metastatic sites for targeted therapy planning Selecting patients for Lu-177 PSMA radioligand therapy PSMA PET CT is significantly more sensitive than conventional bone scans and CT scans for detecting prostate cancer spread. In Bangalore, Dr. Prathap H.J. uses PSMA PET CT as part of the theranostics pathway for prostate cancer patients. Read about PSMA PET CT in Bangalore Ga-68 DOTANOC PET CT Scan This scan targets somatostatin receptors, which are present on neuroendocrine tumour (NET) cells. Ga-68 DOTANOC binds to these receptors, making even small NETs visible on imaging. Conditions detected Neuroendocrine tumours of the pancreas, gut, and lungs Carcinoid tumours Pheochromocytoma and paraganglioma Medullary thyroid carcinoma Meningiomas Ga-68 DOTANOC PET CT also plays a critical role in determining whether a patient is eligible for Lu-177 DOTATATE peptide receptor radionuclide therapy (PRRT). More about DOTANOC PET CT in Bangalore CXCR4 PET CT Scan CXCR4 PET CT targets the chemokine receptor CXCR4, which is overexpressed in several blood cancers. This is a specialised scan not available at most centres. Primary applications Multiple myeloma Certain lymphomas Chronic lymphocytic leukaemia Adrenocortical carcinoma Learn about CXCR4 PET CT in Bangalore Exendin PET Scan Exendin PET targets GLP-1 receptors and is specifically designed to locate insulinomas. These are rare pancreatic tumours that produce excess insulin. They are often tiny (under 1 cm) and nearly impossible to find with conventional imaging. Read about Exendin PET scans in Bangalore CAIX PET CT Scan CAIX (Carbonic Anhydrase IX) PET CT targets a protein overexpressed in clear cell renal cell carcinoma. This scan helps identify kidney cancer lesions and plan targeted radioligand therapy. More about CAIX PET CT in Bangalore GPC3 PET CT Scan GPC3 (Glypican-3) PET CT targets a protein found on hepatocellular carcinoma (liver cancer) cells. This is among the newest PET CT tracers available in Bangalore for liver cancer patients. Learn about GPC3 PET CT in Bangalore Trivehexin PET CT Scan Trivehexin is a newer integrin-targeting PET tracer that can visualise tumour angiogenesis (new blood vessel formation). It provides information about tumour biology that other tracers cannot. Read about Trivehexin PET CT in Bangalore How to Choose the Right PET CT Scan The choice of tracer depends entirely on your clinical situation. Your oncologist or treating physician will recommend the appropriate scan based on: The type of cancer suspected or confirmed Whether this is initial staging or follow-up Previous imaging results Whether radioligand therapy is being considered In some cases, your doctor may recommend two different PET CT scans. For example, a patient with prostate cancer might get both a PSMA PET CT for disease mapping and an FDG PET CT to assess aggressive components. PET CT Scan in Bangalore: What Sets This City Apart Bangalore (Bengaluru) offers more types of PET CT scans than most Indian cities. While FDG and PSMA are available in many tier-1 cities, tracers like FAPI, CXCR4, Exendin, CAIX, GPC3, and Trivehexin are available only at select centres. Dr. Prathap H.J. practises nuclear medicine in Bangalore and offers a comprehensive range of PET CT scans and radioligand therapies.
