24 Απρ 2023 · Brain positron emission tomography (PET) scans provide functional assessments of different physiological and pathophysiological cerebral changes. PET scans allow us to clinically visualize glucose or amino acid metabolism, dopamine receptors, as well as amyloid and tau deposits in the brain.
A PET scan can compare a typical brain (left) with one affected by Alzheimer's disease (right). The loss of red color with an increase in yellow, blue and green colors shows areas of decreased metabolic activity in the brain due to Alzheimer's disease.

Used mostly in patients with brain or heart conditions and cancer, PET helps to visualize the biochemical changes taking place in the body, such as the metabolism (the process by which cells change food into energy after food is digested and absorbed into the blood) of the heart muscle.
A PET/CT brain scan takes pictures of your brain as it works. It is often done to check for tumors that may be causing memory problems or seizures. Before we start your scan, we will inject a radioactive tracer called 18 FDG. FDG stands for 2-Deoxy-2-[18F] fluoro-D-Glucose. Some cancer cells and inflamed cells use more energy than healthy cells.
