Why is a positron emission tomography (PET) scan used in Parkinson's disease?

ANSWER

This scan uses small amount of radioactive material known as a tracer injected into a vein. The tracer triggers a reaction between positively and negatively charged particles to make an image. With people with Parkinson’s PET scans can check brain activities in the area involved with movement. The scan also can check for certain kinds of cancer, such as breast, lung, colon, and prostate cancers.
