Diffusion-Weighted MRI in Acute Subcortical Infarction by Michael B. Singer, June Chong, Dongfeng Lu, Wouter J. Schonewille, Stanley Tuhrim, and Scott W. Atlas Stroke Volume 29(1):133-136 January 1, 1998 Copyright © American Heart Association, Inc. All rights reserved.

Seventy-year-old patient with 72 hours of new left hemiparesis. Seventy-year-old patient with 72 hours of new left hemiparesis. A, Axial proton density–weighted MRI. B, Axial T2-weighted MRI. C, Axial DW MRI (diffusion sensitivity direction cephalocaudad axis). D, Axial DW MRI (diffusion sensitivity direction cephalocaudad axis). Note multiple focal lesions in the subcortical white matter and deep gray matter on proton density (A) and T2-weighted (B) images. From these images, it is not possible to discern which lesion, if any, is acute. DW images (C, D) at the same two slice locations demonstrate a single focus of high intensity in the posterior limb of the right internal capsule (D), indicating the acute infarction. Michael B.
