【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。方法搜集我院行MSCT检查的PAU病例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例均表现为动脉壁上的壁在性充盈缺损并伴有龛影,龛影口部与动脉腔相连,可呈"狭颈征"表现。间接征象包括局部或弥漫性动脉壁内血肿(IMH),动脉瘤及动脉壁粥样斑块、内膜钙化等。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。更多还原

【Abstract】 Objective To discuss and evaluate the value of multi slice spiral CT angiography in the diagnosis of Penetrating Atherosclerotic Ulcer.Materials and Methods 17 patients of PAU were collected and examined with MSCT,analyze the location,radiological diagnosis and complications of PAU on axial,CTA and 2D/3D images.Results Ulcer-like aortic projections were observed of 17 patients,and connected with aortic cavity,where "narrow neck sign "was shown.The indirect signs included localized or extensive IMH,calcification of aortic wall and dilatation of aorta.Conclusion Multi slice Spiral CT Angiography is an effective method for the diagnosis of PAU by providing valuable information for the diagnosis and treatment.更多还原
