Overview
Structural MRI of the brain may be helpful in the diagnosis of Alzheimer's disease. Characteristic findings on MRI suggestive of Alzheimer's disease include reduced hippocampal volume and medial temporal lobe atrophy.
MRI
- Structural MRI of the brain may be helpful in the diagnosis of Alzheimer's disease. Characteristic findings on MRI suggestive of Alzheimer's disease include: [1] [2] [3]
- Reduced hippocampal volume
- Medial temporal lobe atrophy
- Findings on MRI in an elderly patient with memory loss demonstrates cerebral volume loss, particularly pronounced in the temporal and parietal lobes, consistent with the clinical impression of Alzheimer disease.
- Multiple white matter T2 hyperintense regions are suggestive of chronic small vessel ischemic change.
