Positron emission tomography (PET) is an imaging technique used to provide doctors and patients with more information about how cells in the body are working. So what is the connection between Parkinson's disease - a progressive disorder of the nervous system that affects movement throughout the body and causes muscle stiffness - and the role of PET Scans?

positron emission tomography scan is called a PET scan. A PET scan is used in cancer treatment. It can be done with a CT scan. That's why doctors call it a PET/CT scan. However, people often just call it a PET scan.

Positron emission tomography, also known as PET, PET Scan, or PET/CT, is a medical imaging technique that creates images that show the location of metabolically abnormal cells in the body. Doctors often use this technique to diagnose cancer and determine the progression of the disease.

Using a radioactive high-tech (PET) scanner can help patients with certain types of cancer avoid unnecessary, non-curable surgery. This new imaging method, although expensive, can "see" cancer much better than a conventional CT scan.
