Image Findings

SWI images showed numerous small hemorrhages throughout the deep brain, consistent with diffuse axonal injury. In these images, the small hemorrhages in the corpus callosum and thalami are better seen on the SWI image than on the conventional GRE (Gradient Echo) image.

Image Findings

SWI images showed multiple small hemorrhages throughout the deep brain, consistent with diffuse axonal injury. In these images, the small hemorrhages in frontal and temporal lobes, and midbrain, are better seen on the SWI image than the conventional GRE image.

Image Findings

SWI shows extensive dark signal outlining the surface of the brain, consistent with subarachnoid hemorrhage. A dark fluid or FLAIR image shows bright signal in the parietal sulci, confirming recent bleeding. Hyperdense subarachnoid hemorrhage was also seen on computed tomography images (not shown).
