磁共振尿路水成像与CR静脉肾盂造影效果对比

目的：探讨磁共振尿路水成像的临床应用价值。方法：将行静脉肾盂造影检查的34例患者再行磁共振尿路水成像检查,将静脉肾盂造影检查的CR图像和磁共振尿路水成像检查的图像像进行对比;结果：通过比较两者的图像,发现磁共振尿路水成像检查优于静脉肾盂造影检查,磁共振尿路水成像能充分显示肾实质、肾盂、输尿管、膀胱以及泌尿器官与周围组织的关系。结论：磁共振检查时间相对较短,后处理功能强大,重建图像清晰,能够显示CR静脉肾盂造影无法显示的细节病变,特别对微小病变的检出率优于CR静脉肾盂造影检查,但是费用相对较高,如排除费用的因素可取代CR静脉肾盂造影。

Comparison of Value Between MRU and CR in Excretory Urography

Objective To discuss the value of MRI in clinical diagnosis. Methods Images between CR excretory urography and MRU were compared, which came from the results of 36 cases who were examined by both CR and MRU. Results The spiral MRU images were better than those of the CR excretory urography, and at the same time, the relationship between the parenchyma of the renal, renal pelvis, ureter, bladder and the urinary organs and adjacent tissues were displayed clearly. Conclusion The scanning time of MRI is shorter. The machine can not only reconstruct powerfully but also work out better images, and the result is better than MRI which can＇t detect pathological changes in detail in its images. Therefore MRI can be replaced by MRU if the higher cost can be afforded.
