Question

Quizplus · Accepted Answer

A DaTscan is a type of imaging test used to measure the levels of dopamine in the brain. It is often used to help diagnose Parkinson's disease and other movement disorders. The scan involves the injection of a radioactive tracer that binds to dopamine transporters in the brain, which can then be visualized using imaging equipment. A DaTscan cannot diagnose brain tumors or measure brain damage caused by plaque or tangles.
