Computed tomography (CT) and ultrasound were equally effective in measuring the external diameter of atherosclerotic abdominal aortic aneurysms in 20 patients. Ultrasound was superior for determining the true lumen caliber and detecting mural thrombi. CT was superior for demonstrating aortic wall calcifications, but no more so than a plain film abdominal radiograph. Ultrasound should be the method of choice in the diagnosis, serial evaluation and management of a patient with an abdominal aortic aneurysm.
计算机断层扫描（CT）和超声在测量20例腹主动脉粥样硬化性动脉瘤的外径方面效果相当。在确定真腔内径和检测壁内血栓方面，超声更具优势。在显示主动脉壁钙化方面，CT更具优势，但并不比腹部平片更显著。超声应作为腹主动脉瘤患者诊断、连续评估和管理的首选方法。
