摘要
主动脉夹层(AD)是一种严重危及患者生命的心血管疾病,病情复杂多变,进展迅速,病死率高。及时、准确、全面的诊断是指导治疗、降低病死率的关键。多层螺旋CT扫描速度快,分辨率高,扫描覆盖范围广,具有重要应用价值,目前已经成为诊断AD最重要的影像学检查方法;经胸超声心动图/经食管超声心动图是合并急性/慢性肾衰竭或对比剂过敏的急性AD可疑患者初次检查的首选方法;磁共振成像适用于部分慢性AD患者的检查。
Aortic dissection(AD) is a cardiovascular disease that is a dangerous threat to human health. The complicated and fast development state of AD usually leads to high death rate. Hence, to diagnose AD betimes, accurately and comprehensively plays important roles in clinical treatment in order to reduce death rate. In recently years, imaging diagnosis has made great achievements, for instance, with its high scanning speed, high definition and wide scanning coverage, multi-slice computed tomography(MSCT) has very important application in clinical condition. Actually, MSCT is one of the most important medical imaging exams. Meanwhile,other medical exams such as transthoracie echocardiography, transoesophageal echocardiography, magnetic resonance imaging have very important application as well.
