Mesial temporal lobe assessment. Diagonal lines = gray matter of the cortex. (a) Illustration (left) and coned-down coronal T1-weighted MR image (right) obtained for the assessment of mesial temporal atrophy show normal entorhinal cortex (blue arrows), hippocampus, and perirhinal cortex (red arrows) volumes. (b) Corresponding illustration (left) and MR image (right) in a patient with clinical mild cognitive impairment shows moderate to severe atrophy of the entorhinal cortex (blue arrows) and hippocampus and moderate atrophy of the perirhinal cortex (red arrows).
