Fig 5. — Images from a 53-year-old man with chronic hypertensive encephalopathy and acute mental status change. The patient was agitated and confused. Multisection T2-weighted FSE (repetition time [TR]/echo time [TE]_eff = 2800/120 ms) image (A) and standard single-shot, fast spin-echo, fluid-attenuated inversion recovery (SS-FSE-FLAIR) images at different levels (B–D). The T2-weighted FSE image is severely degraded by motion artifact. Images in B to D show no obvious motion artifact, though the patient moved during the acquisition of the images as shown by the change in angulation of the head between sections. In D, obvious high-signal-intensity areas are seen anteriorly in the subarachnoid space. More subtle changes are seen posteriorly. These mimic subarachnoid hemorrhage. A slight increase in gray-white matter contrast is seen in the frontal region in D, consistent with the brain in this region not having experienced the initial inversion pulse. The brain shows extensive white matter change.
