e-CASES: Scheltens score for of Alzheimer Disease on MRI - MTA-scale for Medial Temporal lobe Atrophy (Scheltens)
Scheltens score for of Alzheimer Disease on MRI
The MTA-score (Scheltens) should be rated on coronal T1-weighted images. on a slice through the corpus of the hippocampus (level of the anterior pons).
The scale is based on a visual score of the width of the choroid fissure, the width of the temporal horn, and the height of the hippocampal formation.
- score 0: no atrophy
- score 1: only widening of choroid fissure
- score 2: also widening of temporal horn of lateral ventricle
- score 3: moderate loss of hippocampal volume (decrease in height)
- score 4: severe volume loss of hippocampus
< 75 years: score 2 or more is abnormal.
> 75 years: score 3 or more is abnormal.
|Score||Width of choroid fissure||Width of temporal horn||Height of hippocampal formation|
