A DaT scan, or dopamine transporter scan, is a type of SPECT (single photon emission computed tomography) imaging used to assess the function of dopamine transporters in the brain. It is primarily utilized for the differential diagnosis of movement disorders, particularly to help differentiate between Parkinson’s disease (PD) and other conditions that can cause similar symptoms, such as essential tremor or other atypical parkinsonian syndromes.
