Linear regression analyses showed associations between PCC [18F]FDG SUVr and visuospatial functioning in bvFTD patients with PCC hypometabolism (pinteraction = 0.044, eta2 = 0.208, standardized beta[SE] = 0.163[0.075]) using cerebellum as reference region, as well as with memory (pinteraction = 0.002, eta2 = 0.419, standardized beta[SE] = 0.263[0.073]), and CDR (pinteraction = 0.042, eta2 = 0.264, standardized beta[SE] = −0.434[0.104]) using the pons as reference region.
