What to expect during your PET/CT exam:

• Resting Phase: The PET/CT procedure typically lasts 2-3 hours. It begins with an injection of a tiny amount of radioactive glucose (sugar) “tracer” solution that enables evaluation of glucose metabolism (function) in the body. There are no known side effects to this injection. Once injected, you will be asked to rest in a quiet room and avoid significant movement or talking, which may alter the localization of the tracer. The resting period lasts approximately 60 min.
• Imaging Phase: The PET/CT scanner is very similar in size to a CT scanner and looks like a large doughnut. You will be asked to lie on an imaging table with a pillow positioned under your knees for additional comfort. It will take approximately 30-45 minutes for your scan and possibly longer depending on the type of scan your physician has requested. It is very important that you not move during the scan.
