Routinely: • MTA scales to describe hippocampal atrophy • GCA to describe amount of global atrophy per lobe as well as any asymmetry • White matter hyperintensity scales (the Fazekas or ARWMC) for burden of vascular pathology Upon indication: • Posterior atrophy scale (the Koedam scale) (and other regional descriptors) (e.g. in suspected PCA and FTD)

GCA, global cortical atrophy; MTA, medial temporal atrophy; PCA, posterior cortical atrophy; FTD, frontotemporal dementia; ARWMC, age-related white matter changes
