The first 18 F-flortaucipir PET study in a small number of patients within the LBD spectrum [7 DLB, 8 PD with cognitive impairment (PDCI), and 9 PDNC] showed an increasing trend of cortical 18 F-flortaucipir binding [ 68 ]. 18 F-flortaucipir binding was increased in the inferior temporal and precuneus cortices in DLB and in the same area in PDCI, with a lower level of statistical significance.
