A patient after a major head trauma showing diffuse axonal injury with small hemorrhagic lesions in the medial part of both thalami (arrows, a) and multiple lesions near the cortico-subcortical junction (arrowheads, a and b) seen as hypointensity on gradient-echo-weighted imaging (a and b). Multiple additional lesions can be seen on SWI imaging (c and d) demonstrating the superiority of SWI imaging in diffuse axonal injury.
