FIGURE 1. (A) 99mTc-TRODAT-1 brain SPECT and MR images of 62-y-old male VP patient. Symmetric and normal uptake of 99mTc-TRODAT-1 in bilateral basal ganglia is observed (L = left image). Multiple small infarcts are seen bilaterally in basal ganglia and white matter (arrow) on MR image (R = right image). (B) 99mTc-TRODAT-1 brain SPECT and MR images of 62-y-old male Parkinson’s disease patient. Asymmetric and low uptake of 9mTc-TRODAT-1 in right putamen is observed (L = left image). No obvious abnormality is seen bilaterally in basal ganglia and white matter on MR image (R = right image).
