摘要: 磁敏感加权成像(SWI)是在梯度回波序列基础上进一步发展的成像技术,对顺磁性物质极其敏感。随着SWI的临床普及,目前广泛应用于脑灌注和侧支循环以及颅内静脉血栓形成预后的评估,且对颅内动脉血栓的显示有助于评估缺血性卒中病因和疗效。本文综述SWI在脑血管病中的应用进展,以为脑血管病的诊断、评估和治疗提供更多参考信息。

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.
