摘要
目的：探讨输尿管癌多层螺旋CT尿路造影（MSCTU）的影像特点和诊断价值。材料和方法：回顾性分析18例经手术病理证实输尿管癌的MSCTU表现。18例均行MSCT平扫、增强动、静脉期扫描、多次排泄期扫描及薄层重建，且均行MPR、CPR、VR、MIP重组。结果：增强动、静脉期轴位图像及MPR、CPR重组能够清晰显示肿块及其与周围组织的关系，尤其CPR通过尿液或造影剂对比，可连续显示整条输尿管及肿块；VR及MIP重组对充盈造影剂的输尿管管腔能很好显示肿块引起的不规则狭窄或截断。结论：MSCTU能够多平面、多方位、立体显示输尿管癌，并能客观评判双侧肾脏排泄功能，为临床治疗提供全面帮助。
Abstract
Objective: To evaluate the diagnostic effect and characteric of MSCT urography in ureteric carcinoma. Materials and Methods: To analyse the MSCT features in 18 cases of ureteric carcinomas confirmed by pathology. Conventional scan and contrast enhanced scan including arterial phase, venous phase multiple-delay-phase scan were performed in all cases. The reconstruction methods such as MPR, CPR, VR, MIP were performed. Results: Axial images of arterial and venous phases together with MPR, CPR show the relationship between the tumor and its tissues around it clearly, especially CPR, it can well and continually show the whole ureter and the tumor through the contrast of urine and contrast medium, VR and MIP reconstruction are also good in showing the irregular stenosis and obstruction by the tumor. Conclusion: MSCT urography shows the ureteric carcinoma clearly from multiple planar, multiple directions . It offers a good method to clinical treatments.
