F-DOPA PET-CT Scan is a molecular imaging test generally used to study Parkinsons Disease. An F18-DOPA labeled radioisotope is administered and studied under Positron Emission Technology (PET), while a Computed Tomography / CT Scan is concurrently performed for anatomical detailing. The combination of F-DOPA and PET-CT scanning could be used to image the dopaminergic system in diagnosis of Parkinson’s disease (PD)
