目的 探讨螺旋CT各种成像方法在评价输尿管病变中的临床应用价值。方法 应用螺旋CT对 1 1 0例经临床和病理证实的输尿管病变做平扫及四期增强扫描 ,并作多平面重建 (MPR)和三维重建 ,观察螺旋CT各种成像方法显示和诊断病变的能力 ,并与其他检查技术及手术病理结果进行比较。结果 1 0 7例患者螺旋CT轴面结合曲面MPR能很好地显示输尿管病变的部位、大小、形态和分布范围及尿路梗阻的情况 ,曲面MPR更为直观 ;81例手术患者 ,输尿管病变在螺旋CT图像上的表现与手术所见有很好的一致性。三维重建可获得类似于X线尿路造影的图像 ,能立体显示病变的状况。螺旋CT扫描能很好地弥补其他影像学检查的不足。结论 螺旋CT扫描范围大 ,分辨率高 ,对输尿管病变的显示和诊断有优越性 ,尤以曲面MPR价值最大 ,具有很高的临床应用价值。
Objective To investigate the clinical value of various spiral CT imaging methods in the evaluation of ureteral lesions. Methods One hundred and one cases of ureteric lesions confirmed by clinical and pathological examination were scanned by plain spiral CT (MSCT) and enhanced by four stages using multi-slice spiral CT. Multiple planar reconstruction (MPR) and three-dimensional reconstruction were performed. Spiral CT imaging was used to display and diagnose the lesions Ability, and compared with other examination techniques and surgical pathology results. Results The MPR of 107 cases with spiral CT axial surface showed the location, size, shape and distribution of ureteric lesions and urinary tract obstruction. The MPR of the surface was more intuitive. In 81 cases of surgery, ureteral lesions were Spiral CT image performance and surgical findings have good consistency. Three-dimensional reconstruction can be obtained similar to the X-ray urography images, three-dimensional display of the status of the disease. Spiral CT scan can well make up for the lack of other imaging studies. Conclusion Spiral CT scan range, high resolution, the display and diagnosis of ureteral lesions have advantages, especially the maximum value of curved MPR, with high clinical value.
