A positron emission tomography, or PET, scan is an image that helps physicians diagnose how your tissues and organs are functioning. A PET scan uses a radioactive injection, called a tracer, to show this activity.
The tracer material collects in areas of your body that have higher levels of chemical activity, which often correspond to areas of disease. On the PET scan, these areas show up as bright spots.
A PET scan helps physicians or surgeons diagnose or evaluate several conditions, including specific cancers, heart disease and brain disorders. The procedure is safe and noninvasive. You should have no discomfort other than the small injection involved, and there are no side effects from the injection or the scan.
Typically, the entire process takes approximately one to two hours from the time you arrive for your appointment.
Once you have been injected with the tracer, you will rest for 45 minutes. Then you will be asked to lie on a table that passes slowly through a large doughnut-shaped PET camera, which captures pictures of the entire body.
Preparing for Your PET or PET/CT Scan
- Do not exercise for 48 hours prior to your appointment.
- Do not eat, drink or chew anything other than plain water for six hours before your appointment.
- Try to drink two glasses of water before your appointment.
- If you are diabetic, your blood sugar level must be 200 or under to have the exam performed, and you cannot take diabetic medications for five hours before the exam. Please bring your medication with you to the exam. Please call us at (516) 255-9555 for instructions if your blood sugar is above 100.
- If you have any previous CT, MRI, PET or bone scan images, please bring them with you to your appointment.
- Late arrival could postpone your appointment, as the radioactive sugar solution used in the PET is created and shipped specifically for your appointment date and time, and has a very short shelf life.
