目的探讨多层螺旋CT主动脉血管造影及其后处理技术对主动脉夹层的诊断能力和临床应用价值。方法回顾性分析经手术证实10例主动脉夹层的多层螺旋CT血管造影资料和在工作站上后处理技术的应用。结果轴位图像与多种后处理图像结合后能清晰显示主动脉夹层的精细解剖和与周围组织的毗邻关系,能够清楚的显示主动脉夹层的真假腔及撕裂的内膜。结论多层螺旋CT主动脉血管造影技术结合工作站后处理对主动脉夹层具有很高的诊断价值,对于患者选择治疗方案、指导临床医师手术方法的选择及其观察术后疗效具有很重要的实用价值。
Objective To investigate the diagnosis and clinical value of aortic dissection by multi-slice spiral CT aortography and its post-processing technique. Methods Retrospective analysis of 10 cases of aortic dissection confirmed by multi-slice spiral CT angiography data and workstations on the application of post-processing technology. Results Axial images combined with various post-processing images clearly show the fine dissection of the aortic dissection and the adjacent tissue with the surrounding tissue, which can clearly show the true and false lumen of the aortic dissection and the torn intima. Conclusions Multi-slice CT aortography and workstation post-processing have high diagnostic value for aortic dissection, which is of great practical value for patients to choose the treatment plan, guide the selection of the clinician’s surgical method and observe the curative effect .
