A PET Scan (Positron Emission Tomography) is an imaging test that is used to show the function of your tissues and organs. A radioactive drug called a “tracer” is injected in tiny doses into the arm, and then a large tube-shaped camera takes pictures of the tracer inside the body. The tracer allows doctors and researchers to see areas in your body that have both typical and atypical functions. PET scans are often used to discover the presence of amyloid plaque in the brain, which is a hallmark of Alzheimer’s disease.
Please note that Samuel's experience is meant to represent a "typical" visit, but each clinic's policies and each diagnostic protocol may differ slightly from the one you see on the screen.
