摘    要:
目的:探讨和评价多层螺旋CT(MSCT)及后处理技术对穿透性动脉粥样硬化性溃疡(PAU)的诊断和临床应用价值。方法搜集行MSCT检查的PAU患者17例,以轴位CT图像为主,结合CTA及影像后处理技术对PAU的部位、影像表现及合并征象综合进行图像分析。结果17例患者发病部位于胸主动脉14例,腹腔动脉1例,肠系膜上动脉1例,右侧髂总动脉1例。 CT增强扫描均表现为动脉壁上的突起龛影,龛影口部与动脉腔相连,破口最大约2 cm。8例可见“狭颈征”表现;13例合并动脉壁血肿;1例合并降主动脉瘤并附壁血栓;1例并肠系膜上动脉夹层形成;并纵隔血肿1例;3例可见内膜移位;4例单发,13例多发。结论MSCT是一种有效、无创的诊断PAU及其合并症状的影像检查方法,能为临床诊断、术前评价及随访提供重要信息。

关 键 词:动脉粥样硬化  溃疡  体层摄影术,螺旋计算机  诊断显像

Abstract:
Objective To discuss and evaluate the value of multi slice spiral CT angiography in the diagno -sis of penetrating atherosclerotic ulcer materials .Methods 17 patients of PAU were collected and examined with MSCT,the location,radiological diagnosis and complications of PAU on axial ,CTA and 2D/3D images were analyzed. Results Ulcer-like aortic projections were observed of 17 patients,and connected with aortic cavity ,where "narrow neck sign "was showed .The indirect signs included localized or extensive IMH ,calcification of aortic wall and dilata-tion of aorta .Conclusion Multi slice spiral CT angiography is an effective method for the diagnosis of PAU by provi -ding valuable information for the diagnosis and treatment .
Keywords:Atherosclerosis  Ulcer  Tomography,spiral computed  Diagnostic imaging
