MRI Neuroimaging for Patient Case Presentations. Selected axial MRI diffusion weighted (left column) and fluid-attenuated inversion recovery (FLAIR) images for DS and ER patient case scenarios. These images were obtained at the time of acute stroke presentation (arrival of patients to the hospital). Bright areas on diffusion-weighted images indicate restricted diffusion (in these cases acute stroke). Note the R MCA distribution stroke for patient DS and the scattered L MCA distribution stroke for patient ER. Also note the severe leukoariosis (white matter hyperintensities in the periventricular areas) present for patient ER on FLAIR sequence
