PET scans and PET-CT scans are used for a number of reasons, most frequently to diagnose cancer and evaluate the effectiveness of cancer treatments. If you’ve been referred to an imaging center in San Antonio for a PET scan, this video will give you information about how to prepare and what to expect.
The medical imaging center will advise you whether you need to avoid eating or drinking before your scan. Be prepared to be at the imaging center for a few hours, as you must wait for the tracer used during the scan to work its way through your body. The scan is painless, but you will need to be still for the test, which can take up to an hour.
