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

关 键 词:尿路梗阻性病变  磁共振成像  尿路造影术

Abstract:Objective To evaluate the diagnostic value of magnetic resonance urography (MRU) Methods 310 patients were examined with heavy T 2 weighted fast spin echo pulse sequence to acquire image and postprocedure processing was performed with maxmium intensity projection (MIP) algorithm Presence of urinary tract obstruction was detected in 157 patients Results In 157 patients with urinary tract obstructive disorders, there were: ureteral carcinoma (20), calculus (31), benign stricture (33), congenital ureteral stricture (48), ureteral obstruction caused by extrinsic diseases (10), bladder disorder (15) MR urography provided high resolution image of the urinary tract capable of determining the presence, degree , level, and cause of the obstruction Conclusions MR urography is a safe, and noninvasive, and highly efficient method for detecting urinary tract obstructive disorders
Keywords:Urologic diseases    Magnetic resonance image    Urography
