Dopamine Active Transporter Scan

What is a dopamine active transporter scan?

A dopamine active transporter scan (DaTscan) is a test used to identify early signs of Parkinson’s disease. DaTscans are most often used on patients whose only symptom is a minor trimmer. If your health care provider recommends you have a DaTscan, the test can help your clinician determine whether you have Parkinson’s disease or a different illness.

During a DaTscan, a clinician will inject a mildly radioactive chemical into your bloodstream. Using nuclear imaging technology, your provider will check the supply of a particular type of neuron in your brain. Low supply of these neurons may confirm a Parkinson’s diagnosis.
