Types of PET CT Scans Available in Bangalore
Bangalore has several centres that offer PET CT scanning, but not all centres offer the same range of tracers. The most widely available tracer is FDG, used for general cancer imaging. More specialised tracers such as PSMA (for prostate cancer), FAPI (for tumours that FDG may miss), and Ga-68 DOTANOC (for neuroendocrine tumours) are available at select centres with nuclear medicine departments that have the necessary equipment and expertise.
The type of scan you need depends on your cancer type and what information your doctor is looking for. Before booking, confirm that the centre offers the specific tracer your doctor has requested. You can explore the different types of PET CT scans to understand which one applies to your case.
What to Look for in a PET CT Centre
Equipment: Modern digital PET CT scanners produce higher resolution images than older models. Better image quality can make a difference in detecting small lesions. Ask whether the centre uses a digital PET CT scanner.
Reporting specialist: PET CT images should be interpreted by a nuclear medicine physician or a radiologist with specific training in PET CT. The quality of the report matters as much as the quality of the scan itself. Complex cases benefit from a specialist who understands the clinical context and can provide nuanced interpretation.
Turnaround time: Ask how long it takes to receive the report. For urgent clinical decisions, a faster turnaround may be important. Some centres provide preliminary results within 24 hours.
Preparation Tips
General preparation guidelines are similar across centres, but the specifics can vary depending on the tracer being used. For FDG PET CT, fasting for 4 to 6 hours is standard. For PSMA or FAPI PET CT, fasting requirements may differ. Always follow the preparation instructions provided by the centre where your scan is booked.
Bring your referral letter, previous imaging reports and CDs if available, and a list of your current medications. This information helps the nuclear medicine team provide the most accurate interpretation.
Questions to Ask Your Doctor Before Booking
Before scheduling your scan, consider asking your doctor these questions:
Which type of PET CT do I need (FDG, PSMA, FAPI, or another tracer)?
Why is this scan being done now, and what are you looking for?
Are there any specific preparation steps I need to follow?
How will the results be used in my treatment plan?
These questions help you understand the purpose of the scan and feel more prepared for the appointment.
After the Scan
Once your scan is complete and the report is ready, your referring doctor will review the findings with you. If you receive the report before your appointment, avoid trying to interpret it on your own. PET CT reports use technical language that requires clinical context to understand properly.
