it is used to detect and sometimes differentiate it from other conditions. It is used by the doctor to take decisions about treatment plans.
Fasting for minimum 6 hours with only a few sips of plain water if required.
Diabetes medicine can be taken 12 hrs prior to the procedure.
Fasting Blood sugar levels have to be checked on the same day. The level should be less than 180 mg/dL. It is rescheduled if – greater than 200 mg/dL.
Avoid any intense and strenuous physical activity or exercise 24 hours before the scan.
If in doubt about pregnancy, women patients should do a pregnancy test. If positive, PET-CT is generally not recommended.

Doctor’s prescription or note indicating the type of scan to be done.
Entire current medical file and prescription set to be aware of any medical conditions and allergies, including details of treatment history.
All relevant previous reports, CDs and scan images (MRI, CT scan of the brain and any previous Brain PET-CT scan reports).
Recent Serum Creatinine and Blood sugar reports (preferable to do it on the day of the scan in our lab since it is most indicative of the blood sugar and creatinine levels at that time).
Only one accompanying person is recommended.
Home-cooked food for the patient to eat after the scan.
Total time: 3-4 hrs.
Waiting time after injection: 1 hr.
Scan duration: 10 mins.
A PET – CT scan uses a radioactive material (tracer) to produce 3D images of organs and areas within the body while they are working. The changes that take place are recorded in a sequential manner which is as follows:
After the registration formalities are completed, a Patient Care Co-ordinator will discuss the detailed patient history with you and you will have to share all the relevant treatment details, reports, and doctor’s prescription. You will be given a detailed explanation about the scan experience. At this point, you can get all your queries resolved.
Please bring along all your previous scans CDs as this is important for comparison.
The staff nurse will then prepare you for your scan by giving you the clothes required for the scan and asking you to remove all sorts of jewellery on you.
Please do show your recent Serum Creatinine and recent Blood Sugar reports during the discussion on your health history. It is preferred to do both the tests on the same day to give an accurate diagnosis. If you don’t have these already, you can get them done at our pathology lab. The reports for the same will be available easily and promptly before the PET-CT scan begins.
The radiotracer is pushed in the vein through the cannula. After the injection, you would be asked to relax and rest for an hour in a separate room at our centre. This will help the radiotracer to get absorbed in your body before you are taken for the scan.
Once you’re ready, you’ll be escorted into the scanning room. The Technologist will give you all the necessary instructions before the scan begins. Please do not worry, you are constantly being monitored.
A contrast dye may be injected during the scan, if the doctor needs further information to make his diagnosis. The Contrast Media used depends on the Serum Creatinine levels. The type of Contrast to be used will be decided by the technical team.
The doctor checks the scan and gives instructions to the staff nurse to take you out of the room comfortably.
Sometimes, an additional delayed scan may be required.
After receiving a good to go signal from the doctor you can change, eat something and have your medicines.
Patients can eat, drink and take medication.
Patient is required to be under observation in the clinic for approximately half an hour after the scan, till the concerned staff confirms.
It is best for the patient not to be close to children or pregnant women for the rest of the day to avoid exposing them to any radiation.
For appointment call 8869906990 or write at firstname.lastname@example.org atleast 1 or 2 days prior to the required date of appointment.
(if another scheduled patient has cancelled we may consider taking in walk-in patients. Do check in with our reception and our billing executives at our centre.)
We may have to reschedule or cancel appointments at times because of reasons beyond our control – short-supply or no supply of the FDG used for the scan from an external source, machine breakdowns, etc.
As we have no control over this situation, Medcare Diagnostics would not be held liable for any harm or loss arising out of such cancellations.
