123I-MIBG myocardial scintigraphy for differentiating Parkinson's disease from other neurodegenerative parkinsonism: A systematic review and meta-analysis

The present meta-analysis confirmed high sensitivity and specificity of 123I-MIBG myocardial scintigraphy for differentiating PD from other neurodegenerative parkinsonism in both early and delayed imaging phases. Furthermore, 123I-MIBG myocardial scintigraphy was highly effective for distinguishing early PD.
