Specificity of datscan
WebPeople with DLB have reduced levels of the dopamine transporter protein (DAT) in a part of the brain known as the corpus striatum. It is possible, using tracers that bind to the dopamine transporter, to identify this reduction on certain brain scans (PET or SPECT scans). This is known as DAT imaging.
