摘要 目的探讨体素内不相干运动成像(IVIM)对膀胱尿路上皮癌病理分级及侵袭程度的诊断价值。方法选择2016年10月~2018年6月行体素内不相干运动(IVIM)检查的膀胱尿路上皮癌患者120例。根据病理分期将其分为低级别组和高级别组;根据是否侵袭肌层将其分为非肌层侵犯和肌层侵犯两组患者。对比分析各组ADCst、D、f及D*值,ROC评估IVIM诊断价值。结果低级别组ADCst(2.02±0.21 vs. 1.51±0.23)×10^(-3) mm^(2)/s、D(1.04±0.24 vs. 0.81±0.14)×10^(-3) mm^(2)/s、f(0.57±0.12 vs. 0.47±0.15)高于高级别组,差异有统计学意义(P<0.05)。非肌层侵犯患者ADCst(1.80±0.36 vs. 1.24±0.20)×10^(-3) mm^(2)/s、D(0.98±0.14 vs. 0.72±0.19)×10^(-3) mm^(2)/s、f(0.57±0.11 vs. 0.36±0.12)高于肌层侵犯患者,差异有统计学意义(P<0.05)。ADCst、D及f诊断膀胱尿路上皮癌病理分级的AUC面积分别为0.912、0.842和0.872。ADCst、D及f诊断膀胱尿路上皮癌肌层侵犯的AUC面积分别为0.911、0.840和0.883。结论体素内不相干运动成像(IVIM)对膀胱尿路上皮癌病理分级及侵袭程度具有较高的诊断价值。
