The present study aimed to investigate the association among 18F-PM-PBB3 uptake, neurodegenerative biomarker level, and clinical symptoms in PSP with Richardson syndrome (PSP-RS) patients.\nMethods: 21 patients with probable PSP-RS underwent PET scans with 18F-PM-PBB3 and 11C-PiB for estimating regional tau and Aβ deposition. Plasma neurofilament light chain (NfL) levels were also checked as a neurodegenerative biomarker. Parametric 18F-PM-PBB3- and 11C-PiB- images were generated by voxel-based calculation of the standardized uptake value ratio (SUVR) to the cerebellar cortex. Three patients, who were diagnosed as amyloid-positive by visual assessment of 11C-PiB SUVR image, and two patients lacking some data (PET or NfL) were excluded.

内容記述 | Background and Aims: Our previous studies demonstrated that 18F-PM-PBB3 (18F-APN-1607) uptake may reflect characteristic distributions of tau pathologies in 4-repeat tauopathies including progressive supranuclear palsy (PSP). The present study aimed to investigate the association among 18F-PM-PBB3 uptake, neurodegenerative biomarker level, and clinical symptoms in PSP with Richardson syndrome (PSP-RS) patients. Methods: 21 patients with probable PSP-RS underwent PET scans with 18F-PM-PBB3 and 11C-PiB for estimating regional tau and Aβ deposition. Plasma neurofilament light chain (NfL) levels were also checked as a neurodegenerative biomarker. Parametric 18F-PM-PBB3- and 11C-PiB- images were generated by voxel-based calculation of the standardized uptake value ratio (SUVR) to the cerebellar cortex. Three patients, who were diagnosed as amyloid-positive by visual assessment of 11C-PiB SUVR image, and two patients lacking some data (PET or NfL) were excluded.
