     【摘要】目的探讨多排螺旋CT曲面重建技术在输尿管结石中的临床应用价值。方法 42例输尿管结石患者均采用PHILIPS MX8000 CT机扫描后选取冠状面进行曲面重建。结果所有病例的曲面重建图像均能显示扩张的肾盂、输尿管及输尿管梗阻末端管腔内的高密度结石影。42例患者共获得43幅曲面重建图像，其中图像清晰细腻，无运动伪影及阶梯伪影35幅(81.4%)。图像质量一般，有轻度运动伪影及阶梯伪影8幅(18.6%)。结论曲面重建技术可以使扩张的肾盂、输尿管及输尿管梗阻末端管腔内的高密度结石影全程显示在一幅图像上，图像效果直观明了，对轴扫及多平面重建图像有重要的补充作用，同时对于输尿管结石的临床治疗有一定的指导意义。

    【Abstract】 Objective To study the clinical application of curved planar reconstruction (CPR) for ureteral calculus with multislice spiral CT(MSCT) imaging.Methods 42 cases with ureterolithiasis underwent both helical CT scan and CPR selected coronal plane by PHILIPS MX8000 scaning apparatus.Results CPR pictures in all patients demonstrated the distention of the pelvis,ureter and ureterolith that showed highdensity in the end of dilated ureter,43 pictures were obtained in 42 cases.The pictures showed clearly and none artifacts of movement or footboard in 35 cases(81.4%).The pictures had lightly artifacts in 8 cases (18.6%).Conclusion CPR can display clearly the highdensity calculus that in the dilated pelvis and ureter in one CT picture,it have an important additional contributions for axial scaning and multiplanar reconstruction(MPR),and may play guiding roles in the clinical treatments. ......
