Computed tomography (CT) findings in 11 cases of aortic dissection were correlated with aortographic, surgical, or postmortem findings. In another two patients, the CT findings were considered diagnostic of aortic dissection but no further workup was performed. All the CT examinations were made before and after bolus injection of contrast. Many of the familiar angiographic signs were appreciated on CT, such as a thickened aortic wall, septum between two opacifying lumens, differential time density between the two lumens, and compression of the true lumen. No false-positive or false-negative studies were encountered. This experience suggests that CT is a reliable, noninvasive method for the diagnosis of aortic dissection.
对11例主动脉夹层患者的计算机断层扫描（CT）结果与主动脉造影、手术或尸检结果进行了对比。另外两名患者的CT结果被认为可诊断主动脉夹层，但未进行进一步检查。所有CT检查均在静脉推注造影剂前后进行。CT上可看到许多常见的血管造影征象，如主动脉壁增厚、两个显影腔之间的隔膜、两个腔之间的时间密度差异以及真腔受压。未出现假阳性或假阴性检查结果。该经验表明，CT是诊断主动脉夹层的一种可靠的非侵入性方法。
