About Pet-CTBack to Top ^

What is a PET/CT scan and how does it work?

PET/CT is an advanced imaging test that detects biochemical abnormalities in the body and is usually an outpatient procedure. A radioactive drug called FDG is injected intravenously and is absorbed by tissues and organs. The PET detects the radioactivity emitted by FDG, and the CT provides fine anatomical detail so that the combined PET/CT allows highly accurate detection of disease. Ga-68 peptides PET-CT may be used for prostate cancer and NET tumours. We use the PET-CT for following indications briefly.

• Initial staging of disease,
• Interim PET-CT after 1 to 3 courses of chemotherapy,
• Assessment of therapy response after completion of therapy,
• Restaging of disease.

You may be given an intravenous injection of iodine contrast media sometimes that enhances your CT images.
After the injection you will be asked to sit quietly for approximately one hour within one of our quiet rooms. Due to the radiation pregnant women and children are not allowed to stay with you in the quiet rooms.
After you have relaxed you will be asked to lie down on a table which will move you through the PET/CT scanner. This machine has a larger opening than an MRI, and it does not make any loud noises. The time in the scanner will vary between 20 to 30 minutes.
