Finding disease early with the power of combined scans
PET/CT is a scan obtained on a specialized imaging machine that combines positron emission tomography (PET) with computed tomography (CT). The PET part of the scan is very sensitive at detecting early disease, and the CT part of the scan can show precisely where in the body the disease is located. Combining these strengths allows the PET/CT scanner to accurately evaluate many types of cancer and other diseases such as infection and dementia.
For the PET part of the scan, a small amount of a radiopharmaceutical is introduced into the body, typically by injecting it into a vein. Depending on which radiopharmaceutical is used, it will distribute to the diseased tissue within a few minutes to an hour. It will then emit a type of low dose radiation similar to an X-ray that can be detected by the scanner. At the same time, the CT part of the scan uses additional low dose X-rays to localize the radiopharmaceutical. The scanner then uses the PET and CT information to create an image showing the precise location of the disease in the body.
PET/CT scans are recommended for:
To schedule a PET/CT, please call our scheduling team at (512) 453-6100 or toll free at (800) 998-8214. A provider referral is required to make an appointment.
A radiologist, a physician specifically trained to interpret radiological examinations, will analyze the images and send a signed report to the provider who referred you to ARA. The physician will then share the results with you. Your report will also be available on the patient portal within 3 business days.
