摘要 目的探讨16层螺旋CT多维成像对主动脉夹层动脉瘤的诊断价值及与其他疾病的鉴别诊断。方法对本院2006年4月~2010年4月心内科住院的20例主动脉夹层动脉瘤分别作16层螺旋CT平扫和增强检查,并对其中7例主动脉弓夹层动脉瘤的横断图像和其多维重建成像进行分析。结果 CT平扫显示20例均见病变部位主动脉扩张或各段管腔大小不成比例(100%)。增强CT显示病变区真假两腔内均有造影剂,呈典型"双腔影"6例,1例为阴性,经多维重建显示主动脉弓夹层动脉瘤阳性率为100%。结论 MSCT多维重建能更清晰地显示主动脉弓夹层的直接、间接征象,了解主动脉弓血管受累情况,对临床制定合理的治疗方案提供重要信息,并可作为主动脉弓夹层动脉瘤的首选的诊断及随访检查方法之一。
