| 摘 要： | 本文分析了２３例共２８个先天性胸内大动脉畸形的ＭＲＩ，包括动脉导管未闭、主动脉弓缩窄和离断，主动脉瓣上狭窄，马凡氏综合征及主动脉窦瘤破裂，年龄为３～４５岁。２０例行心血管造影检查，２２例径手术证实。除１例主动脉窦瘤破入右心房和２例较小的动脉导管未闭（＜０．４ｃｍ）外，ＭＲＩ均能做出诊断，敏感性为８９％，与心血管造影比较，ＭＲＩ敏感性９２％，对于主动脉弓极度缩窄和离断的诊断ＭＲＩ可弥补心血管造影的不足。

| Abstract: | In this paper, we analysed the M RI of 28 congenital anomalies of the thoracic aorta and pulmonary arteries in 23 cases, including patent ductus arteriosus, coarctation of aorta, supravalvar aortic stenosis, marfan's synrome, and aneurysm of the sinus valsalva, who ranged in age from 3-45 years. 20 of all cases were examined by angiography, and 21 were confirmed on operation. Excepted for 1 aneurysm of the sinus of valsalva broken into right atrium and 2 small patent ductus arterious (0.4cm) all anomalies were correctly diagnosed on M RI(sensitivity 89.3%).Comparied with angiography, MRI sensitivity was 92%. MRI could be more useful in the diagnosis of severe coarctation of the aorta. |
