FIG 1. MR images obtained on admission.
A, Axial T2-weighted fast spin-echo image (TR/TE, 4390/121). B, Diffusion-weighted image (TR, 6500; b value, 1000 seconds/mm2). C, Apparent diffusion coefficient map. T2-weighted image (A) shows new large lesions mainly involving the bifrontal white matter and the genu of the corpus callosum. Diffusion-weighted image (B) and apparent diffusion coefficient map (C) reveal increased apparent diffusion coefficient in most of the lesions, with decreased apparent diffusion coefficient in the peripheral portions.
