Same-Day PET-CT Appointments — Walk-In Slots in Hyderabad

Yes, a referral or request from your oncologist or treating doctor is required before the imaging centre can proceed. The letter tells the team which body regions to scan and why. If your doctor's clinic is closed and the scan is urgent, contact your CION care team — the request can often be sent electronically so you are not delayed.

Allow two to three hours in total. After the radiotracer injection you wait quietly while it distributes through the body — this uptake period is the longest part of the visit. The scan itself is considerably shorter. Once it is done you are free to leave. Your appointment letter will give you the specific duration for your scan type.

No. You need to fast beforehand — the exact duration will be in your appointment instructions. Eating raises your blood glucose, which interferes with how the radiotracer is taken up by tissues and can affect how clearly the scan reads. Water is generally permitted and encouraged. Follow the fasting instructions the imaging centre gives you, because requirements can vary slightly between centres.

Yes, but you must tell the centre when you call, not when you arrive. Diabetic patients need specific preparation instructions around insulin timing and blood glucose, and the centre needs to give you those guidelines in advance. If your glucose is outside the required range when you arrive, the scan may have to be rescheduled. Disclosing your diabetes at the time of booking prevents that.

Routine reports are read by a nuclear medicine physician or radiologist and typically take one to two working days. If your oncologist needs the report urgently, that request should be made by your treating team at the time of booking — urgent turnaround is sometimes possible but must be arranged with the centre in advance. Asking after the scan has already been done is usually too late to change the timeline.

The cost depends on the body area being scanned, the tracer type, and the specific centre. Any figure quoted online is indicative and may not reflect current rates. The most accurate cost is given by the imaging centre when you have your referral details ready. If you have health insurance or a government scheme, check with your insurer before the scan whether prior authorisation is needed — this is much easier to arrange before the appointment than after.
