Figure 1: (a,b) representative 99mTc-TRODAT-1 SPECT images of an IAD subject in comparison with an age-matched healthy control ((a) a 20-year-old male IAD subject; (b) a 20-year-old male healthy control). Left hemisphere is on right side of image. The IAD subject demonstrates a significant decrease in binding of  99mTc-TRODAT-1 to the DAT in the striatum and the bilateral corpus striatum is much smaller and more irregular than that in the control.
