FIG 2. A 27-year-old woman 24 days after a traffic accident.
A, Axial T1-weighted image show slight enlargement of the lateral ventricules and right subdural bloody effusion (thin arrow).
B, Sagittal trace DW image (b = 1000) shows that the areas of strong high signal intensity in the corpus callosum have moved anteriorly compared with the first MR image (thin arrow).
C, Axial echo planar T2*-weighted image (b = 0 image from DTI sequence) shows no significant hemorrhage in the corpus callosum as a low signal intensity area (arrow).
D, Axial FLAIR image shows high signal intensity area in the anterior part of the corpus callosum (arrows). No significant damage is seen in other white matter areas.
E and F, Diffusion tensor fiber tracking from the seed area around the corpus callosum is shown. Fibers are overlayed on FA map. The view from right side of the patient shows almost no fibers extending up to the upper frontal and parietal white matter (arrows, E). On the frontal view, upward fibers in the right side have almost disappeared (arrow, F).
