Images in a patient with left-sided TLE.
A, Coronal T2-weighted MR image. Note the abnormal anterior hippocampus with mild deformation on the left side compared with the right side.
B, DTI at the same coronal level as in A. Note the marking of the ROI in the left and right HFs. The images in the upper right corner correspond to the diffusion (B0, top), trace D (middle), and FA (bottom) images.
