摘要:
目的 探索MR 扩散加权成像(DWI)对膀胱尿路上皮癌的诊断价值。方法 从2015 年6 月至2016 年12 月,将我院已进行MR 扩散加权成像检查共72 例膀胱疾病患者,根据病理结果分为膀胱良性疾病组(n=23)和膀胱尿路上皮癌组(n=49), 比较膀胱良性疾病组和膀胱尿路上皮癌组术前的肿瘤平均表观扩散系数(ADC)值,采用受试运算特性(ROC)方法确定最佳诊断Cut-off 值。结果 膀胱良性疾病组和膀胱尿路上皮癌术前ADC 值分别为(1.86±0.40)×10-3 mm2/s和(0.93±0.11)×10-3 mm2/s,差别具有统计学意义(P<0.01);ADC 值在肿瘤分级间的差别有统计学意义;ADC 值诊断膀胱尿路上皮癌的ROC 曲线下面积为0.705;ADC 值诊断膀胱尿路上皮癌时兼顾敏感性和特异性的最佳Cut-off 值为1.32×10-3 mm2/s,此Cut-off 值的敏感性和特异性分别为87.2% 和82.9%。结论 MR 扩散加权成像ADC 值可作为一种早期诊断膀胱尿路上皮癌的客观指标。
