FIGURE 2. 123I-FP-CIT binding in different striatal regions in patients with good response and in patients with poor response to L-dopa therapy. ASGR = abnormal study with good response; ASPR = abnormal study with poor response; NSPR = normal study with poor response; SR = right striatum; SL = left striatum; CR = right caudate; CL = left caudate; PR = right putamen; PL = left putamen; P/C R = putamen-to-caudate ratio on right; P/C L = putamen-to-caudate ratio on left.
