Case 2: 52 year-old man with intracranial injuries sustained in a motor vehicle accident. Case 2: 52 year-old man with intracranial injuries sustained in a motor vehicle accident. Brain MR imaging was performed 18 days after the accident. A and B, Axial fast spin-echo T2-weighted (4000/98/1) (A) and FLAIR (11000/125/1) (B) images both show evidence of diffuse axonal injury, as evidenced by hyperintense signal in the splenium.C and D, Isotropic diffusion-weighted (10000/125/1) (C) and diffusion trace (D) images show hyperintense signal and decreased ADC values, respectively, consistent with cellular edema. Of particular interest in this case is that ADC values were decreased well into the subacute period after the injury. Amon Y. Liu et al.
