摘要
目的评估磁共振尿路造影 ( MRU)对输尿管移行细胞癌的诊断价值。方法采用快速自旋回波 ( FSE)重 T2 WI技术的磁共振尿路造影和其他影像学检查方法检测 15例输尿管移行细胞癌患者。结果输尿管中上段癌 11例 ,下段癌 4例 ,MRU共同征象 :梗阻端输尿管腔内有中等信号的肿块 ,呈结节状或分叶状 ,表现为充盈缺损征象 ,梗阻以上尿路扩张。结论 MRU是一种安全、无创的影像学检查方法 ,结合其他影像学检查方法 ,对输尿管移行细胞癌有很高的诊断价值。
Objective To evaluate diagnostic evaluation of MR urography in ureter transitional cell carcinoma.Methods 15 patients were examined with a modified,heavily T 2 weighted fast spin echo pulse sequence.Results 11 tumors were at the upper ureter and 4 the lower.They demonstrated the common patterns as middling signal masses,filling defects and dilatation of the urinary tract above the obstruction.Conclusion MR urography is a safe noninvasive method for detection of the ureter transitional cell carcinoma in combination with other imaging technique.
