Fig 3.

Contiguous axial T2-weighted (A–D) and corresponding T1- weighted (E–H) images in a patient with vasogenic edema. The T2-weighted images exquisitely demonstrate the cortical thickness difference between the precentral and postcentral gyrus (white arrows) because the vasogenic edema outlines the cortex. These findings are only partially visible on the T1-weighted images. There is no discernible difference in cortical thickness of the anterior and posterior bank of sulci in the frontal and parietal lobes (black arrows).
