FIGURE 2. (A and B) SPM glass brain maps of difference in 99mTc-ECD uptake between IPD patients with disease of short (<5 y; A) and long (5–20 y; B) duration vs. healthy volunteers show contrast for decreased perfusion in patients. (C and D) SPM glass brain maps of difference in 99mTc-ECD uptake between IPD patients with disease of short (<5 y) and long (5–20 y) duration. (C) Contrast for relatively decreased perfusion in long-duration patients. (D) Contrast for relatively increased perfusion in long-duration patients.
