Fig. 1. Dopamine transporter image in Parkinson’s disease. A: [18F]-N-3-fluoropropyl-2-betacarboxymethoxy-3-beta-(4-iodophenyl) nortropane positron emission tomography computed tomography in a patient with Parkinson’s disease shows decreased uptake of the dopamine transporter (DAT) in the bilateral putamen, severely on the right side, with an anterior-posterior gradient. B: Normal DAT uptake in the striatum in a healthy subject.
