Why is a PET scan used?
For patients with Parkinson’s disease (PD), a PET scan is used to assess activity and function of brain regions involved in movement. However, doctors may request a PET scan for many different reasons. Aside from potential problems in the brain and spinal cord, the test can also be used to diagnose heart problems as well as certain kinds of cancer, including breast, brain, lung, colon, and prostate cancers and lymphoma.
