【摘要】 目的 评估MR泌尿系造影对尿路梗阻性病变的诊断价值。方法 310例用重T2WI快速自旋回波(FSE)序列作MR泌尿系造影，采集资源影像后作最大信号强度投影(MIP)处理。发现157例为梗阻性尿路扩张。结果 157例梗阻性尿路扩张包括：输尿管癌20例，输尿管结石31例，输尿管良性狭窄33例，先天性狭窄48例，外在性病变致梗阻10例，膀胱病变致梗阻15例。MR泌尿系造影均清楚显示尿路影像，能确定有无梗阻，展示梗阻端的形态和特征，对梗阻水平的定位及梗阻原因的定性均有较高的正确性。结论 MR泌尿系造影是安全有效的非侵袭性影像检查方法，特别适用于静脉肾盂造影(IVP)禁忌证和肾功能丧失者，此技术能成为泌尿系疾病诊断中有用的补充手段。

【 Abstract 】 Objective To evaluate the diagnostic value of magnetic resonanceurography (MRU). Methods 310 patients were examined with heavy T₂ weighted fast spin-echo pulse sequence to acquire image and postprocedure processing wasperformed with maxmium-intensity-projection (MIP) algorithm. Presence of urinary tractobstruction was detected in 157 patients. Results In 157 patients with urinary tract obstructive disorders,there were: ureteral carcinoma (20), calculus (31), benign stricture (33), congenitalureteral stricture (48), ureteral obstruction caused by extrinsic diseases (10), bladderdisorder (15). MR urography provided high-resolution image of the urinary tract capable ofdetermining the presence, degree , level, and cause of the obstruction. Conclusions MR urography is a safe, andnoninvasive, and highly efficient method for detecting urinary tract obstructivedisorders.
