A new technique of computed tomography (CT) applied to the diagnosis of abdominal aortic aneurysms is described, and the experience in 58 patients is reviewed. In all instances the abdominal aorta was clearly demonstrated, even when wall calcification was absent. A series of 37 patients with abdominal aortic aneurysm underwent evaluation by physical examination, abdominal roentgenograms, and ultrasonic and CT scanning. Measurements of the transverse diameter at the point of maximal dilatation were compared with the measurements made at operation. CT not only confirmed the diagnosis in all patients but the measurements obtained by this technique were the most accurate, correlating extremely well with the true dimensions of the aneurysm. The addition of contrast enhancement to CT scanning allowed clear delineation of the aortic lumen and intraaneurysmal thrombus, not possible with any other method, including ultrasonography. The technique appears useful as a screening procedure and in the differential diagnosis of a tortuous abdominal aorta. Patients with a small aortic dilatation can be followed accurately by scanning.
本文描述了一种应用于腹主动脉瘤诊断的计算机断层扫描（CT）新技术，并回顾了58例患者的经验。在所有情况下，即使没有壁钙化，腹主动脉也能清晰显示。37例腹主动脉瘤患者接受了体格检查、腹部X线片、超声和CT扫描评估。将最大扩张点处的横径测量值与手术时的测量值进行比较。CT不仅在所有患者中都能确诊，而且通过该技术获得的测量值最为准确，与动脉瘤的真实尺寸相关性极佳。CT扫描增加对比增强后，可以清晰地勾勒出主动脉腔和瘤内血栓，这是包括超声检查在内的任何其他方法都无法做到的。该技术作为一种筛查程序以及在鉴别诊断迂曲腹主动脉方面似乎很有用。主动脉轻度扩张的患者可以通过扫描进行准确随访。
