摘　　要：目的 :探讨多层螺旋CT(MSCT)平扫多平面重建诊断输尿管结石的价值。方法 :对 3 9例疑诊为输尿管结石的患者行腹、盆部MSCT平扫及输尿管多平面重建 (MPR)。结果 :3 9例MPR成像均清楚显示输尿管 (其中结石 3 5例 ,未见结石 4例 ) ,同时显示结石的大小、形态、位置和输尿管扩张的程度及范围。结论 :MSCT平扫MPR可获得良好的输尿管图像 ,对输尿管结石的诊断及鉴别诊断具有重要价值。Objective:To investigate the diagnostic efficacy of the multiplanar reconstruction (MPR) on multislice spiral CT in diagnosis of ureterolithiasis.Methods:39 patients were examined from the top of the kidneys to symphysis pubis using multislice spiral CT.MPR was used in image postprocessing in our studies.Results:Reformatted CT displayed clearly the entire course of ureter in all 39 cases and ureterolithiasis in 35 of all thirty-nine cases. MPR clearly demonstrate size,shape,location of the stone and the degree of dilatation of ureter in 35 patients.In the rest 4 cases dilatation of ureter was demonstrated,but no ureteral stone.Conclusion:Our findings suggest that the MPR on multislice spiral CT of ureter is valuable in diagnosis of the ureterolithiasis.
