What is a DaTSCAN?

DaTSCAN is the first-and-only FDA-approved imaging agent to aid in the assessment and diagnosis of patients in whom a parkinsonian syndrome or essential tremor is suspected. Dan scan is a nuclear medicine exam, which combines a small amount of radioisotope with a pharmaceutical that is targeted to go to a specific organ. This radiopharmaceutical can be injected, inhaled or swallowed and is absorbed by specific cells within your body. Nuclear medicine exams differ from other radiological exams in that they provide both functional and structural information. The exams are very sensitive and can detect disease at its earliest stage. The exams are safe, relatively painless and the radiation exposure is similar to that of other diagnostic X-Ray exams
