PET/CT
Positron Emission Tomography (PET), combined with CT, is a diagnostic examination most often used to detect cancer. It’s also used to determine whether a growth is malignant (cancerous) or benign (noncancerous), evaluate the progression of disease, and assess the effects of clinical therapies.
During a PET/CT scan, a radioactive substance is administered to the patient. It travels throughout the body and is absorbed into organs and tissues. More radioactive material collects in cancer cells than in normal cells and appears brighter in the image. PET/CT scans can also be used to evaluate patients with memory disorders like Alzheimer’s Disease and other dementia disorders.
Frequently Asked Questions
PET appointments typically last 2 hours (approximately 20 minutes of that time will be physically on the scanner). The amount of time involved to complete your scan will depend on the type of study your physician has requested. It begins with an injection of a small amount of radioactive “tracer”. You’ll lie comfortably on the slowly moving imaging table while the scanner detects the concentration of the tracer within the body. The procedure may begin immediately upon injection or may begin after an “uptake period,” depending on the study. You may be asked to rest in a quiet room and avoid significant movement or talking, which could alter the localization of the tracer.
The PET scanner is very similar in size to a CT scanner and looks like a large doughnut. You’ll lie comfortably on the slowly moving imaging table while the scanner detects the concentration of the tracer within the body.
