Note.—Data are the number of lesions. Data in parentheses are the number of patients.
* We subjectively assessed lesional conspicuity and categorized it as follows: A, diffusion-weighted imaging was inferior to FLAIR; B, diffusion-weighted imaging was equal to FLAIR; and C, diffusion-weighted imaging was superior to FLAIR.
