摘　　要：主动脉夹层（aortic dissection,AD） 指主动脉腔内的血液通过内膜的破口进入主动脉壁囊样变性的中层而形成夹层血肿,随血流压力的驱动,逐渐在主动脉中层内扩展而形成,是主动脉中层的解离过程.是一种危重心血管疾病,发病凶险,3 个月生存率仅10% [1].历来AD 的影像学检查主要有X 线胸片、CT、超声、MRI,自造影技术应用于临床以来,DSA、CTA 和MRA 在临床AD 的诊断中占有不可忽视的地位,本文就X 线胸片、DSA、CT、MRI、超声几种影像检查方法在AD 的诊断进展予以综述.Purpose：Aortic dissection （AD） refers to aortic cavity blood through the endometrial crevasse into the aortic wallcystic degeneration of the middle and the formation of interlining hematoma,With the blood pressure in the driver, graduallyin the aorta middle-level formed within the extended, it is the aorta middle-level disintegrate process. Is a criticalcardiovascular disease, pathogenesis ill-tempered, three months surial only 10%.Traditionally Aortic dissection imagingexaminations are mainly X-ray sternum, CT, MRI, ultrasound, since imaging techniques applied to clinical since, DSA, CTA andMRA in clinical diagnosis of AD occupies cannot ignore the status, this paper X-ray sternum, DSA, CT and MRI, ultrasonicseveral imaging methods in AD to review progress diagnosis.
