What is a DaTscan and how is it performed?
In 2011, the Food and Drug Administration (FDA) approved an imaging test to help diagnose Parkinson’s disease (PD) called DaTscan (dopamine transporter scan). In this test, a radioactive tracer, Ioflupane (123I), also known as DaTscan, is injected into the blood, where it circulates around the body and makes its way into the brain. It attaches itself to the dopamine transporter, a molecule found on dopamine neurons. Several hours after the tracer has been injected, special imaging equipment scans the head to detect the presence of DaTscan.
