What is a DaTscan?

A DaTscan is a nuclear medicine scan that we use to rule out Parkinson's disease as the cause of essential tremor. It looks at the dopamine transporters in the striatum of the brain. We use a nuclear tracer called isoflupane, which is injected into the patient's veins. This makes its way up to the brain and tags the dopamine transporters, which allows us to see if the patient has a dopamine deficiency. This essentially rules out Parkinson's disease, thereby helping us eliminate that as a cause of essential tremor.
