摘要 目的探讨肝动脉多普勒血流灌注指数在肝转移瘤鉴别诊断中的应用价值。方法用彩色多普勒测量患者的DPI,对比肝脏转移组、未转移组及对照组的差异,并随访各组的DPI测值。结果肝转移组与未转移组、对照组的DPI测值差异有统计学意义,DPI≥0.35作为发生肝转移的诊断标准,其准确率为90.57%,灵敏度81.82%,特异度92.86%,阳性预测值0.75%,阴性预测值95.12%,假阳性率0.25%,假阴性率4.88%。有1例测量DPI>0.35后3个月肝内检出转移灶。2例单发的转移灶进行局部介入治疗,半年后复查DPI<0.35。结论DPI可作为胃肠道恶性肿瘤肝转移的预测指标、肝内转移灶治疗的预后及疗效随访指标。
