The application of susceptibility⁃weighted imaging in cerebral vascular disease

Abstract

Susceptibility ⁃weighted imaging (SWI) is a type of MRI developed based on gradient echo sequence (GRE). It is extremely susceptible to paramagnetic substances. The application of SWI has spread to various aspects of clinical practice, including the assessment of brain perfusion and collateral circulation, and the prognosis of intracranial venous system thrombosis. Furthermore, the sign of intracranial arterial thrombi on SWI helps to evaluate the etiology and outcome of ischemic stroke. To provide more information on the diagnosis, evaluation, and treatment of cerebrovascular diseases, we reviewed the application of SWI in cerebrovascular disease.
