目的 本研究应用MSCT、MRU对泌尿系统结石进行成像,评价两种检查方法的优劣,进一步提高影像的诊断准确性.方法 采用多层螺旋MSCT及高场MRI对泌尿系统疾病患者进行检查,应用工作站后处理方法进行图像处理,各由两位影像专家进行图像分析.结果 本研究共收集78例患者,78例结石患者均经MSCT检查,其中60例经MR检查.MSCT平扫对结石显示的敏感度为100%,特异度为100%,MRU对结石显示的敏感度为96%,特异度为90%.MSCT 2.5 mm层厚重建图像显示小结石总数与5 mm层厚扫描图像相比,有明显统计学差异(P=0.000),MR对小结石均未能良好显示.MSCT、MRU两者总体图像质量无显著差异(P=0.53).厚层MRU图像质量优于多层薄层MIP重建MRU重建图像(P=0.041).结论 MSCT平扫薄层重建对于显示小结石具有明显的优势.MRU无电离辐射,适用于婴幼儿或孕妇患者.MSCT、MRU扫描范围大,均适用于多病灶患者的检查,结合原始图像,可以全面评价患者泌尿道疾病.

Objective To research the imaging of urinary system of CT Urography and MR Urography.Evaluate the advantage and disadvantage of the two kind of examinational methods. In order to improve the diagnostic accurate of urinary system, and reduce the cost of examination. Methods To examine the urinary system of patients through multi-slice CT and(or) MR. Then process the images of CT or MR at workstation. The postprocessed images analyzed by two radiologists respectively. Results 78 cases with calculus of urinary system examined through CT were collected in our investigation, 60 cases among of them examined through MR. The sensitivity and specificity of calculus detection of CT were 100% and 100.0% respectively,while those of MR urography were 96% and 90%,There was significant difference between section widths of 2.5 mm of reconstructed images and 5.0 mm with regard to the number of detected microlith (P=0.000), All microlith failed to manifestate on MR images. There was no significant difference between the pictures quality of CT and MRU images (P=0.53). Thick slab MRU had superior image quality to multisection MIP MRU (P=0.041). Conclusion CT plain scan lamellar reconstruction has an advantage to demonstrate microlith of urinary system. MR urography allows the evaluation of pediatricand pregnant patients without the use of ionizing radiation. The large scan range of MSCT and MRU provide only one examination on patients with multi-focus. Combined with conventional images to provide a comprehensive evaluation of the urinary tract diseases of patients.
