64排容积CT后处理技术对输尿管梗阻的诊断

摘要

Objective To investigate the diagnostic value of post-processing technique for ureteral obstruction. Methods All cases were confirmed by surgery or clinical data. 64-slice volume CT (VCT) was performed in 90 cases with ureteral obstruction. The volume data of all patients were reconstructed with 3D reconstruction techniques in-cluding multiple planar reformation (MPR), and volume rendering technique (VR), and curved planar reformation (CPR). Results Among the 90 cases,there were 78 cases of ureteral calculus, 4 ureteral and bladder carcinomas, 2 congenital malformations,and 1 inflammatory stenosis. Conclusion 64-slice VCT and post-processing technique have unique advantage for the etiology and level diagnosis of ureteral obstruction ,which have important significance for clinical treatment programs.%目的：探讨64排螺旋CT后处理技术对输尿管梗阻的诊断价值。方法选取我院2010年6至2013年6月间90例经临床确诊输尿管梗阻病例，所有病例均行64排容积CT扫描并进行多平面重建（multipla-nar reformatting，MPR）、容积重建（volume rendering technique，VR）、曲面重建（curved planar reformation，CPR）等处理。结果90例输尿管梗阻中78例由于输尿管结石所致，邻近器官压迫5例，输尿管癌或膀胱癌4例，先天畸形2例，输尿管炎1例。结论64排容积CT平扫及多种后处理技术对输尿管梗阻病因及定位诊断具有很高的临床应用价值，对临床治疗方案的选择具有重要指导意义。
