[Improved diagnosis of dementia with Lewy bodies by the combination of 123I-metaiodobenzylguanidine (MIBG) myocardial scintigraphy and 99mTc-ethylcysteinate dimmer (ECD) brain perfusion SPECT].

Clinical diagnostic criteria for dementia with Lewy bodies (DLB) include abnormal findings on MIBG myocardial scintigraphy and occipital hypoperfusion as supportive features. In this study, 36 patients with probable DLB underwent MIBG scintigraphy and brain perfusion SPECT. The results of SPECT were analyzed using three different cerebral blood flow (CBF)-analyzing programs, an easy Z-score imaging system (e-ZIS), 3DSRT, and FineSRT.
