SLC6A3 and Lewy body dementia: Abnormal findings on dopamine transporter (DAT) imaging were considered the most important among the various neuroimaging features listed as one of the suggestive features of DLB, whereas findings from other neuroimaging techniques, including 123I-metaiodobenzylguanidine (MIBG) myocardial scintigraphy were listed only as supportive of DLB (commonly present in DLB but not proven to have diagnostic specificity).
