DatScan is a specific type of single-photon emission computed tomography (SPECT) imaging technique that helps visualize dopamine transporter levels in the brain
Why its done
DaTscan is a tool used to confirm the diagnosis of Parkinson’s disease.
Basic Principle
A radioactive agent is injected into the patient’s bloodstream
The agent is taken by the brain cells and tracked using SPECT
DaTscan specifically marks the brain cells that carry the dopamine transporters.
The higher the number of healthy cells having the transporter protein is, the brighter the images are.
In this way, the intensity of the brain images determines the health of the brain cells.
