How does a PET scan work?
During a PET scan, two medical images are captured with one machine at the same time - a PET image and a CT image. The PET image shows the physician how the body is functioning and reveals areas of abnormal activity. The CT image shows the physician the body's anatomic structure, acting as a map to precisely locate any areas of concern. The images are combined to reveal the complete picture to the physician.
To better understand how a PET scan works, think about a satellite weather map seen on the local news. The map displays weather patterns gathered by satellites that show storm intensities. With one image on top of the other, we can see what areas are being affected by adverse weather.
What will I experience during the procedure?
Before a PET scan, patients are injected with a small amount of radioactive glucose through a small IV. There is no danger associated with this injection, because the radiation exposure is the same as that associated with a conventional CT scan.
Once the glucose has been injected, patients are made comfortable on a recliner for 90 minutes before being positioned in the PET scanner for the pictures. Patients are asked to remain still for the duration of the examination.
To prepare for the exam
Taking medication is okay; check with the PET center regarding diabetic medications.
If you have diabetes, ask the doctor for specific diet recommendations for test day, since accurate results depend on normal body chemistry levels.
Tell your doctor if you are pregnant, think you might be pregnant or if you are a nursing mother.
Wear comfortable clothing in layers.
Avoid all food and beverages except water for at least four hours before your scan.
