- Fig 1.
A 59-year-old woman with intracranial hemorrhage. A right thalamic hemorrhage with intraventricular extension to the right lateral ventricle shows mainly hyperintensity on T1-FLAIR (A and G), hyperintensity on T2WI (B and H) and T2-FLAIR (C and I), blooming artifacts on T2*WI (D) and SWAN (J), and diffusion restriction on DWI (E and K) (arrows in each sequence). These findings are well-visualized on both EPIMix MR imaging (A–F) and routine MR imaging (G–L).
- Fig 2.
A 48-year-old woman with brain abscesses. There are 2 irregularly shaped masslike lesions with perilesional edema in the right temporal lobe. The internal content shows hypointensity on T1-FLAIR (A and G) and hyperintensity on T2WI (B and H) and T2-FLAIR (C and I) (arrows). The internal content shows diffusion restriction on DWI (E and K) (arrows). There are blooming artifacts on T2*WI (D) and SWAN (J) (arrows). These findings are well-visualized on both EPIMix MR imaging (A–F) and routine MR imaging (G–L).
- Fig 3.
A 52-year-old man with Wernicke encephalopathy. Signal changes in the tectal plate of the midbrain and periaqueductal gray matter showing hypointensity on T1-FLAIR (A and G), hyperintensity on T2WI (B and H) and T2-FLAIR (C and I), and hyperintensity on DWI (E and K) are well-visualized on both EPIMix MR imaging (A–F) and routine MR imaging (G–L) (arrows in each sequence).
