Computerized tomography allows good definition of the retroperitoneal space, especially the abdominal aorta. During a 15 month interval, 30 patients with pulsatile, abdominal masses were evaluated by computerized tomography to determine the presence of an aortic aneurysm, 4 centimeters or greater in size. Twenty-one of the 30 patients were found to have an aneurysm. In patients with a normal aorta, information concerning another disease process was often obtained. Results of computerized tomography were then compared with the other diagnostic techniques available and, in certain instances, with the size of the aneurysm at operation. Computerized tomography is the most accurate means of evaluating abdominal aortic aneurysms. The ability to detect a retroperitoneal space hemorrhage and to assess the pathologic condition of other abdominal viscera are two additional advantages.
计算机断层扫描能够很好地显示腹膜后间隙，尤其是腹主动脉。在15个月的时间里，对30例有搏动性腹部肿块的患者进行了计算机断层扫描，以确定是否存在直径4厘米或更大的主动脉瘤。30例患者中有21例被发现患有动脉瘤。在主动脉正常的患者中，常常能获得有关其他疾病进程的信息。然后将计算机断层扫描的结果与其他可用的诊断技术进行比较，在某些情况下，还与手术时动脉瘤的大小进行比较。计算机断层扫描是评估腹主动脉瘤最准确的方法。能够检测腹膜后间隙出血以及评估其他腹部脏器的病理状况是另外两个优点。
