FIG 5. Axial MR images obtained in a 75-year-old man with transient left hemiparesis.

A, Fast-FLAIR T2-weighted MR image shows multiple focal lesions in the subcortical white matter. It is not possible to discern whether any of the lesions are acute.

B, Diffusion-weighted MR section obtained at the same level as A depicts a single focus of high signal intensity in the left centrum semiovale suggestive of acute infarction.
