Evaluation of Brain SPECT with ^99mTc-TRODAT-1 in the Differential Diagnosis of Parkinsonism

Figure 2

Comparison of SPECT-TRODAT results among patients with Parkinson’s disease and other Parkinsonisms. Normal results and those that did not correspond to the clinical picture (symmetry) were considered negative. For the calculations, unilateral and bilateral results were considered different. PD = Parkinson’s disease, MSA = multisystem atrophy, LBD = Lewy body dementia, DIP = drug-induced Parkinsonism, VP = vascular Parkinsonism.
