摘　　要：目的:探讨电子束CT(EBCT)对急性主动脉综合征(AAS)的临床应用价值.方法:采用Imatron C-150型EBCT扫描机,连续容积增强扫描,对82例主诉急性胸背痛患者进行EBCT检查.结果:82例AAS患者,主动脉夹层(AD)56例,主动脉壁内血肿(IMH)15例,穿透性粥样硬化性溃疡(PAU)11例.EBCT能够显示三种疾病的特征性征象:AD可见内膜片和双腔征;IMH主动脉壁呈新月形或环形增厚≥5mm;PAU为凸出于主动脉管腔外的造影剂充盈的龛影.结论:EBCT是一种快速、无创的检查方法,能为AAS的诊断提供重要信息.EBCT可作为AAS诊断有用的检查方法.AIM： To investigate the clinical value of electron beam CT （ EBCT ） in acute aortic syndrome （AAS）. METHODS ： EBCT scanner was used with a model of Imatron C- 150. Contrast-enhanced continuous volume scanning （CVS） was performed. Eighty-two patients who complained of acute pain in the chest and back were scanned by EBCT. RESULTS： Eightytwo cases included 56 cases of aortic dissection（AD）, 15 cases of intramural hematoma （IMH） and 11 cases of penetrating atherosclerotic ulcer （PAU）. EBCT depicted the imaging features of AAS： AD showed the intimal flap and true and false lumens; IMH showed crescent or circular thickening of aortic wall ; PAU showed a focal fill of contrast medium outpouching the aortic lumen. CONCLUSION： EBCT is a fast and noninvasive examination technique. It provides important information for the diagnosis of AAS and can be used as the useful means in the diagnosis of AAS.
