1 A–C, DWI san (A) at the level of the atria of the lateral ventricles reveals areas of acute (hyperintense) infarction in the frontoparietal region and an area of relative hypointensity due to encephalomalacia in the left frontal lobe. A–C, DWI san (A) at the level of the atria of the lateral ventricles reveals areas of acute (hyperintense) infarction in the frontoparietal region and an area of relative hypointensity due to encephalomalacia in the left frontal lobe. On the b0 EPI scan (B) the old infarction is hyperintense. Note hypointensity on both the DWI (A) and b0 EPI (B) scans in the right periatrial region, indicative of chronic hematoma. GRE scan (C) reveals multiple punctate foci of hemosiderin deposition that are not apparent on any other pulse sequences. The right periatrial hematoma is hypointense. D–F, DWI (D), b0 (E), and GRE (F) images at the level of the foramen of Monro reveal a chronic right thalamic hematoma, which is hypointense on all pulse sequences; however, the numerous foci of hypointensity are seen only on the GRE scan (F).
