摘　　要：目的:探讨原发性输尿管癌的CT表现及螺旋CT三维重建的诊断价值。方法:分析8例经病理证实的原发性输尿管癌的螺旋CT表现。其中6例行平扫及增强扫描,1例平扫,1例逆行尿路造影后行CT平扫。结果:平扫肿块呈轮廓不清的软组织影,增强扫描更清晰;肿块纵向蔓延范围大于横向,MPR或CPR显示更直观。结论:螺旋CT平扫及增强扫描是确诊原发性输尿管癌的必不可少的影像检查方法。Objective:To discuss the CT manifestations of primary ureter carcinoma and the value of 3D reconstruction of spiral CT in the diagnosis.Methods:SCT imaging manifestations of primary ureter carcinoma which were confirmed pathologically in 8 cases were analyzed.Among them,6 cases were given plain CT scanning and CE CT scanning,1 case was given plain CT scanning,1 case was given plain CT scanning after retrograde pyelography.Results:On plain CT scanning,the tumors appear as soft tissue shadows with hazy outline,which were better shown on CE CT;The growth of tumors in longitudinal direction was more marked than that in cross-section,which was better shown on MPR or CPR.Conclusion:SCT plain scanning and CE scanning are indispensable imaging method in the diagnosis of primary ureter carcinoma.
