螺旋CT是一种结合连续管球转动及连续床进的新技术,有利于数据采集以提供连续的解剖信息,而不象常规CT对层面交界人为设置界线。作者对15例患者行螺旋CT血管造影,年龄平均62岁,86％(13/15)有腹主动脉粥样硬化病理改变,需外科或介入性治疗。10例靶位显示肾动脉,3例显示内脏循环,2例显示腹主动脉。步骤采用扫描器用1cm Spiral CT is a new technique combined with continuous tube rotation and continuous bed advancement, which facilitates data acquisition to provide continuous anatomical information rather than setting the boundaries for conventional CT to level boundaries. The authors of 15 patients underwent spiral CT angiography, mean age 62 years, 86% (13/15) pathological changes of abdominal aortic atherosclerosis, requiring surgical or interventional treatment. Ten cases showed renal artery, three showed visceral circulation, and two showed abdominal aorta. Step using a scanner with 1cm
