Before revision:  Mean amyloid load (AV45-PET), glucose metabolism (FDG-PET), and gray matter volume (MRI) was calculatedfor each brain region. Separate GGMs were estimated using a Bayesian framework for the combined multimodal data for each diagnostic category.
After revision:  Mean amyloid load (AV45-PET), glucose metabolism (FDG-PET), and gray matter volume (MRI) were calculated. GGMs were estimated using a Bayesian framework for the combined multimodal data for each diagnostic category.
