Relationship between MTA visual scale scores and hippocampal volume measured by a medicaldevice in patients from a multicentric memory clinic population

The medial temporal lobe (MTL), including the hippocampus, undergoes atrophy in patients with Alzheimer's disease (AD). Visual rating of medial temporal lobe atrophy (MTA) is often performed in the assessment of patients with cognitive impairment. Calculation of hippocampal volumes (HV) can also be achieved by multiple automated and semi‐automated methods using T1‐weighted MR images. The current study investigated the relationship between HV and z‐scores calculated by an automated method, included in the QyScore® medical device, and visual MTA rating scores using Scheltens’ scale in a multicentric memory clinic population at baseline.
