Imaging Alzheimer in 2011

Abstract

Over the past two decades, MRI has come to play a prominent role in the diagnosis of Alzheimer Dementia (AD). Findings that have a high sensitivity for AD are medial temporal lobe atrophy (Fig. 1) and parietal atrophy (Fig. 2), especially when both are present in the same patient. If MRI is contraindicated or not available, CT is a good alternative with which global and medial temporal lobe atrophy as well as the extent of white matter lesions may be reliably assessed.
