The presently available diagnostic methods for abdominal aortic aneurysms are reviewed. The application of ACTA scanning for this diagnosis in 35 patients is described. In all cases the presence of an aortic aneurysm was confirmed, even when calcification of its wall was absent. Contrast enhancement demonstrated that aortic lumen not otherwise visualized. In some instances the iliac arteries were clearly seen and more readily so when calcified. Estimates of aneurysm size were compared with measurements taken at surgery with a relatively close correlation. This technique seems to be useful in the differential diagnosis with tortuous abdominal aorta or as a screening procedure. Patients with minimal ectasia of the aorta can be followed by scanning. The planned addition of shorter scanning times and sagital scans with allow the fast evaluation of the longitudinal dimension of the abdominal aortic aneurysm, which is difficult to obtain with the present technique.
本文综述了目前可用的腹主动脉瘤诊断方法。描述了35例患者中ACTA扫描在该诊断中的应用。在所有病例中，即使动脉瘤壁无钙化，也证实了腹主动脉瘤的存在。对比增强显示了其他情况下无法可视化的主动脉腔。在某些情况下，可以清楚地看到髂动脉，钙化时更易看清。将动脉瘤大小的估计值与手术时的测量值进行比较，两者相关性较高。该技术似乎在鉴别诊断迂曲的腹主动脉或作为筛查程序方面很有用。主动脉轻度扩张的患者可通过扫描进行随访。计划缩短扫描时间并增加矢状位扫描，这将有助于快速评估腹主动脉瘤的纵向尺寸，而目前的技术难以获得该尺寸。
