1、主动脉壁内血肿的CT血管成像发表时间：2010-2-2411:05:04来源：创新医学网推荐作者：李宝新金东升   作者单位：210008江苏省南京市，南京大学医学院附属鼓楼医院放射科（李宝新）；210024江苏省南京市，江苏省省级机关医院放射科（金东升）【摘要】 目的评价多层螺旋CT血管成像对主动脉壁内血肿的诊断价值。方法对临床怀疑的186例夹层动脉瘤行多层多排螺旋CT扫描，其中确诊夹层动脉瘤105例，主动脉壁内血肿23例，采用多平面重建（MPR），曲面重建（CPR），最大密度投影（MIP）等方法显示壁内血肿及血管壁溃疡并按Stanford分型。结果23例主动脉壁内血肿

2、，6例为A型，17例为B型。CT主要表现为：（1）所有病例见主动脉壁呈新月形或环形增厚，其中增厚的壁≥5mm；（2）5例见主动脉内壁上有溃疡形成；（3）5例并发胸腔及心包积液。在MPR，CPR及MIP上均可清楚显示血肿的部位、累及范围、血肿程度以及并发症。结论16层螺旋CT对主动脉壁内血肿具有重要的诊断及临床应用价值。【关键词】 主动脉；壁内血肿；多层螺旋CT血管成像；血管造影          Clinicalapplicationof16slicespiralCTangiographyinlocatedintheTomb,DongShenJiabang,defert
