FIG 4. Case 10. Sample case in which FLAIR imaging is of little diagnostic value because of severe motion artifacts. Images were obtained 2.5 months after the onset of symptoms.

A, Motion artifacts are so severe on the FLAIR image that it cannot provide diagnostic clues.

B, Diffusion-weighted imaging, however, clearly reveals hyperintense lesions (arrows) in right temporo-occipital cortices and cingulate gyrus.
