What is a PET Scan procedure?
PET scan imaging, or PET is an acronym for Positron Emission Tomography. PET is a test that uses special imaging cameras and a radioactive type of sugar to produce pictures of the function and metabolism of the cells in the body. A PET scan is unique type of imaging test that helps doctors see how the organs and tissues inside your body are functioning.
What is a CT Scan?
CT scan imaging, or CT (Computed Tomography), sometimes referred to as a CAT scan, uses specialized equipment to obtain image data in a 360-degree arc around the body, and then uses advanced computer processing to show thin cross-sectional images of the body tissue.
CT imaging is particularly useful for investigating lung, bone, soft tissue, and blood vessels. With this technology radiologists can more easily diagnose problems such as cancers, vascular disorders, infectious disease, trauma, and musculoskeletal disorders. CT scanning is a very efficient and patient-friendly exam that involves little radiation exposure.
What is a PET/CT Scan?
A PET/CT scan merges both technologies into a single machine. It provides a picture of function (PET) and a picture of anatomy (CT) and a merged picture of both the body’s metabolism and structure.
What to bring and wear for your PET scan?
You must bring your insurance card and the written requisition form from your physician and arrive a minimum of 30 minutes prior to the examination. If applicable, bring a CD copy of any previous PET exams, x-ray, CT or MRI scans done at a different imaging facility for comparison. Wear warm, comfortable clothes – the scanner room is often cool – and avoid clothes with heavy buckles or metal components.
How can you prepare for your PET scan?

How long does a PET scan take?
Once injected into a vein, it typically takes from 45 minutes to 1 hour for the radiotracer to travel throughout the body and be absorbed into the organs or tissues to be examined. The scan itself may take another 30 to 60 minutes. Total appointment time is approximately 2 hours.
