PET-CT for Heart, Brain and Infection: — Does the Price Change?

For most indications, yes. The scanner, the preparation, and the FDG tracer are identical. What changes is what the radiologist is looking for when reading the images. Cardiac perfusion PET — which measures blood flow to heart muscle — uses a different tracer, rubidium-82 or N-13 ammonia, and is a different procedure with different pricing. Standard heart viability PET and brain FDG PET use exactly the same scan as oncology.

No. Most Indian health insurance policies cover PET-CT based on medical necessity, not on the diagnosis. What the insurer needs is a specialist's written referral explaining why the scan is clinically required — not confirmation of the condition it will find. The same policy that covers PET-CT for cancer staging will generally cover it for fever of unknown origin, epilepsy, or heart disease if the referral documents the reason clearly.

Most private insurers turn around pre-authorisation requests within a few working days. Bring your referral letter, your most recent test results, and your policy details when you apply. If the insurer requests additional information from your specialist, responding quickly is the most important thing you can do to avoid delay. Do not book the scan while waiting for approval — book only after you have the written confirmation in hand.

For any scan using the FDG tracer — including heart viability, brain, and infection PET-CT — you will be asked to fast before the scan. Your imaging team will give you written preparation instructions with the exact requirements. Diabetic patients receive different instructions, which may involve adjusting the timing of insulin or oral medication. Tell the imaging team you have diabetes when the appointment is confirmed, not on scan day.

Aarogyasri and PM-JAY cover PET-CT for specified medical indications at empanelled centres, with a fixed ceiling amount. Whether your condition is on the covered list and whether the partner imaging centre is empanelled under your scheme are both things to confirm at the CION centre before you book. If the scan cost exceeds the scheme ceiling, you pay the difference. Bring your scheme card and specialist referral to the appointment.

Cardiac perfusion PET requires rubidium-82 or N-13 ammonia, tracers that need specialist equipment not available at every imaging centre. Availability at CION partner centres varies by location. If your cardiologist has specifically asked for perfusion PET rather than standard FDG cardiac PET, say so when you contact the CION centre — the team will confirm whether it can be arranged at a partner centre near you and advise on the next step.
