FIG 1. A 27-year-old woman 4 days after a traffic accident.
A, Axial T1-weighted image shows the intraventricular hemorrhage in left lateral ventricule (bold arrow) and right subdural effusion. A small hemorrhage in the corpus callosum is seen (thin arrow).
B, Sagittal trace DW image (b = 1000) shows areas of high signal intensity in corpus callosum (thin arrow), especially in the splenium (bold arrow).
C, Axial echo planar T2*-weighted image (b = 0 image from DTI sequence) shows a small hemorrhage in the corpus callosum as a low signal intensity area (arrow).
D, Axial FLAIR image shows high signal intensity area in the corpus callosum (arrows). No significant damage is seen in other white matter area.
E and F, Diffusion tensor fiber tracking from the seed area around the corpus callosum. Fibers are overlayed on FA map. The view from right side of the patient shows some fibers extending up to upper frontal and parietal white matter (E, arrows). On the frontal view, upward fibers in the left side are not seen (F, arrow).
