Full Study Name

Myocardial Scintigraphy and DaTscan for Early Diagnosis of Parkinson's Disease (IRB no. 46442)


This study focuses on patients who have symptoms that are the precursors of Parkinson’s disease (PD), PD, or types of atypical PD. The purpose of the study is to determine whether using two imaging techniques together (myocardial scintigraphy and dopamine transporter scan) is a reliable method for detecting PD early, perhaps even before someone has obvious signs of the disease. Although both imaging techniques are approved by the U.S. Food and Drug Administration for other conditions, their use is considered investigational in this study.
