Representative images of [¹⁸F]-Flortaucipir (left), [¹⁸F]-MK-6240 (center), and [¹⁸F]-PI-2620 phosphor screen autoradiography of brain slices from DLB (a), FTLD-TDP-43 (b) and CAA (c). No binding of any of the three tracers was detected in slices containing Lewy bodies, TDP-43 inclusions or CAA lesions. Abbreviations CAA, amyloid angiopathy; DLB, dementia with Lewy bodies; FTLD-TDP-43, frontotemporal lobar degeneration-TAR DNA binding protein 43. Scale bar = 1 cm
