摘　　要：脑梗死后出血性转化是与急性缺血性卒中相关的最常见的不良事件之一,影响到治疗方案和临床预后评价。本文总结了不同的影像学方法和影像学生物标志物,包括计算机断层扫描、磁共振成像、血管造影成像等方法在预测HT方面的作用,同时也包括不同的影像学生物标志物指标,如早期缺血改变、大的缺血病灶体积、严重的血流受限情况、血脑屏障破坏、不良的侧支循环形成和血流速度高等都与HT风险相关。Hemorrhagic transformation is one of the most common adverse events associated with acute is-chemic stroke, which affects treatment and clinical prognosis. This paper summarizes the role of different imaging methods and imaging biomarkers, including computed tomography, magnetic resonance imaging and angiography in predicting HT, as well as different imaging biomarker indi-cators. For example, early ischemic changes, large ischemic lesion volume, severe blood flow re-striction, destruction of blood-brain barrier, poor collateral circulation formation and high blood flow velocity are all associated with the risk of HT.
