目的　探讨多层螺旋CT(MSCT)血管仿真内窥镜在主 -髂动脉病变中的临床应用价值。方法　对 3 6例临床疑诊主 -髂动脉疾病及 40例腹部检查患者行MSCT血管造影检查 ,之后在图像后处理工作站对可疑血管病变部位行CTVE并观察所获图像质量与扫描技术参数之间的关系。结果　 10例夹层动脉瘤均见撕裂内膜及双腔征 ,16例动脉瘤样病变见瘤腔扩大 ,48例见内膜钙化斑 ,血管内支架及血管置换术后各 1例可见支架形状及换血管部位狭窄 ,血管闭塞 1例见闭塞管腔。结论　CTVE图像质量的好坏与增强技术、扫描参数、运动伪影相关。CTVE是MIP、MPR及SSD的重要补充 ,在血管性疾病的诊断、治疗及疗效观察中有极高的参考价值。

Objective To investigate the clinical value of multislice spiral CT (MSCT) vascular endoscopy in the diagnosis of primary iliac artery disease. Methods MSCT angiography was performed on 36 patients with clinical suspected iliac artery disease and 40 patients undergoing abdominal examination. CTVE was performed on suspicious vascular lesion in image post-processing workstation and observed between the acquired image quality and the scanning technique parameters Relationship. Results 10 cases of dissecting aneurysm were found in the tear and double lumen syndrome, 16 cases of aneurysm-like lesions in the tumor cavity enlargement, 48 cases of endometrial calcification plaque, endovascular stent and vascular replacement in 1 case of stent shape And for vascular stenosis, vascular occlusion in 1 case closed the lumen. Conclusions CTVE image quality is related to enhancement technique, scanning parameters and motion artifact. CTVE is an important complement to MIP, MPR and SSD, and has a very high reference value in the diagnosis, treatment and observation of curative effects of vascular diseases.
