【摘要】：探讨多层螺旋CT血管成像技术（multi-slice computed tomographyangiography, MSCTA）在主动脉夹层（aortic dissection, AD）的诊断价值及MSCTA在诊断AD及主动脉壁内血肿（intramural hematomas, IMH）中的价值，为临床选择适当的、合理的诊疗方案提供帮助。本文收集2010年1月至2012年3月于我院放射科行多层螺旋CT主动脉检查并满足条件的患者共102例，并用常规平扫和CTA增强扫描，检查后将图像传送至工作站进行相关后处理，包括多平面重建（multiplanar reconstruction,MPR）、曲面重建（curved planar reconstruction , CPR）、容积再现（valumerendering，VR）及最大密度投影（maximum intensity projection , MIP），对主动脉病变进行分析，并观察其中的规律。所有统计学处理均由SPSS16.0软件进行分析。结果表明，MSCTA能够较好的显示主动脉病变特点，能较好的鉴别AD及IMH，并能提供除主动脉病变以外的其它并发症，，为临床诊断及治疗提供丰富的影像学依据。
[Abstract]:To investigate the diagnostic value of multi-slice computed tomographic angiography (MSCTAT) in aortic dissection (AD) and the value of MSCTA in the diagnosis of AD and intramural hematomas (IMHs). From January 2010 to March 2012, 102 patients underwent multi-slice spiral CT aortic examination in our radiology department and satisfied the conditions. The images were transmitted to the workstation for post-processing by routine plain scan and CTA enhanced scan. It includes multiplanar reconstruction, curved surface reconstruction, curved planar reconstruction, volumetric reconstruction, maximum intensity projection and maximal density projection. All statistical processing was analyzed by SPSS16.0 software. The results showed that MSCTA could better display the characteristics of aortic lesions, differentiate AD and IMH, and provide other complications other than aortic lesions, and provide abundant imaging evidence for clinical diagnosis and treatment.
