FIG 3. Higher rCBV values are observed in the left globus pallidus and right thalamus in the ex-MDMA users than in the control subjects. After registration in the same orientation (in six control subjects and two ex-MDMA users), an unpaired Student's t-test was performed on each voxel of generated rCBV maps, revealing significant differences in the colored regions (yellow, P < .025; red, P < .005). Images were obtained at intervals of 1202 milliseconds (800/54) before, during, and after injection of contrast agent
