e-CASES: Scale for Age-Related White Matter Changes (ARWMC) on MRI and CT
The ARWMC Rating Scale for MRI and CT
|White matter lesions|
|0||No lesions (including symmetrical, well-defined caps or bands)|
|2||Beginning confluence of lesions|
|3||Diffuse involvement of the entire region, with or without involvement of U fibers|
|Basal ganglia lesions|
|1||1 focal lesion (≥5 mm)|
|2||>1 focal lesion|
White matter changes on MRI were defined as bright lesions ≥ 5 mm on T2, PD, or FLAIR images. Lesions on CT were defined as hypodense areas of ≥5 mm; left and right hemispheres were rated separately.
The following brain areas were used for rating: frontal, parieto-occipital, temporal, infratentorial/cerebellum, and basal ganglia (striatum, globus pallidus, thalamus, internal/external capsule, and insula).
A new rating scale for age-related white matter changes applicable to MRI and CT.
