PET Scan for Tumor Localization
* Inform your physician if you are pregnant or breast feeding.
You have been scheduled for a PET study which involves the use of a small amount of radioactive material. The level of radioactivity used is low and has no side effects.
You will be positioned on an imaging table, inside a special detector called a PET scanner. You will also receive a CT scan of the same area as the PET scan to aid the physicians in interpreting your study.

Nothing to eat or drink 4 hours prior to your appointment

You will be asked to drink a glass of oral contrast. An I. V. catheter will be placed in your arm for an injection of a radioactive tracer. The injection will occur 30 minutes after you drink the contrast. You will have to wait for 1 hour after the injection before your images can be taken. During that hour, you will be instructed to drink a second glass of oral contrast. Images lasting approximately 25 minutes will be then be taken.
