摘　　要：血脑屏障(BBB)破坏是创伤性脑损伤(TBI)所致重要病理变化之一,及时治疗及判断预后具有重要临床意义。目前监测TBI后BBB改变越来越受到重视。本文对TBI后BBB改变、MR灌注加权成像(PWI)及MR PWI研究TBI进展进行综述。Destruction of blood-brain barrier(BBB)is one of the important pathological changes after traumatic brain injury(TBI).Early detection of TBI evaluate and prognosis of TBI patients are of great significances.Monitoring of changes in BBB after TBI have been more and more emphasized in clinical practice.The pathophysiological changes of BBB after TBI and research progresses of MR perfusion weighted imaging(PWI)in TBI were reviewed in this article.
