WVU Medicine Imaging Services uses positron emission tomography (PET), a form of nuclear medicine, and computerized tomography (CT) in a single imaging device to provide more accurate diagnoses than two separate scans. Our PET-CT imaging can also be used to help plan more targeted radiation therapy and reduce the patient’s amount of radiation exposure.
What to Expect
Before the PET-CT exam, a blood glucose check is performed, and a radioactive tracer is injected through an IV. The amount of the radionuclide injected is very small, and there is no need for precautions against radiation exposure. Your entire body will be scanned to obtain a full evaluation of your metabolic activity.
After the scan, you can resume your normal daily activities and eating habits. You’ll need to drink plenty of fluids for the next 24-48 hours to help flush out the radioactive material from your body. Once the PET-CT exam is completed, the images are reviewed by a board-certified radiologist, and the radiologist will send your doctor a report. Your doctor will notify you with the results.
