Diffusion-weighted imaging in acute stroke

Abstract

Diffusion-weighted imaging (DWI) enables the early detection of acute ischemic stroke and with high sensitivity and specificity. The signal changes are based on decreased diffusion of water molecules that is caused by cytotoxic edema. Despite the possibility of early detection of ischemic changes magnetic resonance imaging (MRI) is not normally necessary for the therapy decision; however, under some conditions, such as unknown time from onset of symptoms, multiparametric MRI including DWI can provide useful information that will influence the therapy.

Acute Stroke

A stroke occurs when blood supply to the brain is interrupted depriving the brain of oxygen and nutrients. This feed focuses cerebrovascular accidents including ischemic and paralytic stroke.
