【摘要】 目的:探讨MRI对输尿管病变的诊断价值。方法:回顾性分析经手术和病理证实的输尿管病变19例的MRI资料(均行平扫T1WI、T2WI,其中行增强扫描7例,行MRU检查11例),MRI结果与手术病理结果进行对照分析。结果:19例输尿管病变中原发性输尿管癌7例,膀胱癌侵及输尿管3例,肾结核累及输尿管4例,输尿管畸形4例,输尿管息肉1例。MRI对输尿管病变诊断的定位准确率为100%,定性准确率为94.7%。结论:MRI是用于输尿管疾病的一种很好的诊断方法,对肿瘤与炎症和良性与恶性肿瘤的鉴别、恶性肿瘤的TNM分期及输尿管畸形的详细情形可提供更全面的信息。更多还原

【Abstract】 Objective:To study the value of magnetic resonance imaging for the diagnosis of ureteral diseases. Methods:19 cases of ureteral diseases confirmed by operation and pathology were reviewed.MRI techniques included T1WI and T2WI performed in all patients,enhanced MRI in 7 patients and MRU in 11 patients.MRI findings were retrospectively analyzed and correlated with surgical and pathological results.Results:19 cases of ureteral diseases included ureteral carcinoma (n=7),invasions of ureter by bladder carcinoma (n=3),ureteral and renal tuberculosis (n=4),ureteral anomaly (n=4) and ureteral polyp (n=1).Localization accuracy rates of 100% and specificity of 94.7% were achieved for MRI in the diagnosis of ureteral diseases.Conclusion:MRI is an effective imaging modality for detecting ureteral diseases,it can offer all around information for the differentiation from inflammation to tumor,benign to malignant tumor,also TNM staging of malignant tumor and the detailed condition of ureteral anomaly.更多还原
