Left/right asymmetry of atrophy in semantic dementia: behavioral-cognitive implications.

abstract：:Using (18)F-fluorodopa PET and a constant 0.0062 influx rate in the putamen, dementia with Lewy bodies (n = 7) was distinguished from AD (n = 10) with a sensitivity of 86% and a specificity of 100%. A constant 0.0071 influx rate in the caudate yielded a sensitivity of 71% and a specificity of 100% for distinction of t...
