摘要
目的:本研究应用声辐射力脉冲成像(Acoustic radiation force impulse,ARFI)技术和APRI(AST/PLT ratio index)指数对非酒精性脂肪性肝病(Nonalcoholic fatty liver disease,NAFLD)患者进行检测,探讨和对比上述两项无创技术在诊断NAFLD肝纤维化程度上的临床应用价值。方法:对67例NAFLD患者应用ARFI技术检测肝脏超声弹性,并计算APRI指数,所有患者均于检测后1周内行肝脏穿刺活检,以病理检查结果为金标准,比较ARFI技术和APRI指数对NAFLD肝纤维化的诊断价值。结果:NAFLD患者肝纤维化分期为S0S4期的ARFI和APRI平均值分别为(1.177±0.281)m/s(APRI 0.192±0.155),(1.249±0.308)m/s(APRI 0.190±0.097),(1.436±0.521)m/s(APRI 0.306±0.195),(1.538±0.496)m/s(APRI 0.224±0.094)和(1.857±0.729)m/s(APRI 0.373±0.295),两种技术测值均与肝纤维化分期存在相关,相关系数分别ARFI 0.416(P<0.01)和APRI指数0.254(P<0.05)。ARFI和APRI诊断NAFLD肝纤维化S≥2的ROC曲线下面积分别为0.714、0.653;S≥3的面积分别为0.765、0.577;S=4的面积分别为0.853、0.611。结论:ARFI技术作为实时超声弹性成像技术,较APRI指数能更准确的无创定量评价NAFLD肝纤维化程度,具有良好的临床应用前景。
