Application of susceptibility weighted imaging in patients with acute ischemic stroke / 国际脑血管病杂志

ABSTRACT

Susceptibility-weighted imaging (SWI) is a high resolution, three-dimensional gradient echo T 2* sequence magnetic resonance technique. It uses the different susceptibilities between tissues to display the susceptibility image, which is extremely sensitive to paramagnetic substance such as deoxyhemoglobin and blood breakdown substances. In the acute stage of ischemic stroke, SWI can effectively evaluate the severity of the disease, guide the treatment plan, and predict the clinical outcome. This article reviews the research progress of SWI in the acute phase of ischemic stroke.
