Diffusion-weighted MRI and MR perfusion in an acute period of ischemic stroke

Abstract

In this study, most characteristic clinical and neuroimaging features of different subtypes of ischemic stroke (IS), such as different evolution rates during an acute period of the disease, weredetermined. Despite the lack of differences in the final size of thelesion, more frequent hemorrhagic transformation and theregress of ischemic penumbra in patients with cardioembolicstroke during the first week may be regarded as the evidence of earlier recovery process in this subtype of IS. The obtained dataallowed elaborating an algorithm of application of different MRIregimens for brain visualization in the context of examinationand treatment of patients with acute IS.
