18-F fluorodopa (FDOPA) PET scans of a normal subject (left) and a patient with Parkinson's disease (right). The relative absence of tracer (red = high uptake, blue = low uptake) in the deep grey-matter nuclei (striatum) of the patient with Parkinson's disease reflects the loss of nerve cells in the substantia nigra. The clinical symptoms of Parkinson's disease become apparent when the loss of nigral neurons approaches 80%. Serial FDOPA PET scans have been used to monitor and quantity the progression of Parkinson's disease and to assess the efficacy of potential neuroprotective agents.About
