摘　　要：目的探讨64层螺旋CT尿路造影在泌尿系统全程显示中的应用方法及在泌尿系统器质性病变诊断中的临床应用价值。方法1年内共收集36例患者,均行泌尿系常规CT平扫、三期增强扫描,原始数据传送至高级后处理工作站,使用最大密度投影、多平面重建、曲面重建及容积重建等方法,获得完整排泄期尿路影像;同时部分患者相对照做了静脉肾盂造影。结果均能清晰显示泌尿系统解剖情况,其中正常26例,2例输尿管结石,2例肾盏结石,3例肾癌,1例输尿管癌,2例单侧肾盂输尿管中上段积水。结论64层螺旋CT能够多平面、多方位三维立体显示整个泌尿系统的解剖情况,为临床明确肾脏及输尿管情况提供了重要的参考价值,并能弥补静脉肾盂造影不能观察到的角度或部位。Objective To investigate the application of manifesting the urologic diseases and the clinical diagnostic value of urologic diseases with 64-slice spiral CT urography. Methods 36 eases accepted non-enhanced multi-slice spiral CT and contrast-enhanced MSCT examination in one years. The original data were dell with to the workstation,then the whole excretory urologic images were obtained with MIP,MPR,CPR,VR and so on. Some of the 36 cases underwent intravenous pyelography in order to be compared. Results The structure of urologic diseases was clearly displayed in all of these cases. Of the 36 cases,26 cases of normal,2 cases of ureteral calculus,2 cases of pyelic calculus,3 cases of renal cell carcinoma, 1 case of ureteral carcinoma and 2 cases of unilateral renal pelvic and ureteral dilation. Conclusion 64-slice spiral CT is highly valuable for the diagnosis of renal and ureteral diseases, and can also demonstrate the parts of that the IVP can＇t observe.
