[F-18]-AV-1451 phosphor screen autoradiography (left) and nuclear emulsion autoradiography microphotographs (right) from tissue blocks containing choroid plexus of CTE (a, case #1) and severe brain vessel disease (b, case #2) subjects. Autoradiography signal was observed in case #1, corresponding to the presence of leptomeningeal melanocytes. Scale bar = 20 μm (right). Abbreviations: CTE = chronic traumatic encephalopathy
