Question

Quizplus · Accepted Answer

PET scan stands for Positron Emission Tomography, a highly specialized imaging technique that can detect changes in cellular function. It uses a radioactive tracer that is injected into the patient's bloodstream, which then accumulates in different parts of the brain depending on the level of activity in those areas. As the tracer decays, it emits positrons, which can be detected by the PET scanner and used to create an image of the distribution of the tracer in the brain. This allows doctors and researchers to study the functioning of various regions of the brain and identify abnormalities that may be related to cognitive or neurological disorders.
