目的 探讨CT仿真内镜 (CTVE)在主动脉病变诊断中临床应用价值。方法 5例正常和 1 3例主动脉病变行主动脉螺旋CT增强扫描 ,通过软件行主动脉CTVE成像。 1 3例有主动脉病变 ,其中夹层动脉瘤 6例 ,主动脉瘤3例 ,单纯主动脉血栓 2例 ,主动脉硬化 8例 ;5例为正常人。结果 主动脉CTVE可清晰显示正常血管内壁或病变的血管内腔形态 ;能显示正常主动脉内腔及主要分支开口情况、夹层动脉瘤的真假腔及内膜瓣、主动脉瘤的形态等正常解剖结构及异常病变。结论 CT仿真血管内镜是一种新的、无创性的检查诊断方法 ,它在主动脉病变的诊断及治疗中有着独特的价值 ,但有待进一步提高
Objective To investigate the clinical value of CT virtual endoscopy (CTVE) in the diagnosis of aortic lesions. Methods Aortic spiral CT was performed in 5 cases of normal and 13 cases of aortic lesions. Aortic CTVE imaging was performed by software. 13 cases of aortic lesions, including 6 cases of dissection aneurysm, 3 cases of aortic aneurysm, simple aortic thrombus in 2 cases, aortic atherosclerosis in 8 cases; 5 cases were normal. Results aortic CTVE can clearly show the normal vascular wall or lesion vascular lumen morphology; can show the normal aortic lumen and the main branch opening situation, the true and false lumen dissection aneurysm and endometrial flap, aortic aneurysm morphology is normal Anatomy and abnormal lesions. Conclusion CT virtual endoscopy is a new and noninvasive diagnostic method that has unique value in the diagnosis and treatment of aortic lesions but needs to be further improved
