摘　　要：目的研究腹部超声在诊断和鉴别肝脏肿块中的价值。方法125例肝脏肿块患者,均进行腹部超声检查以及病理诊断。根据病理诊断结果,分析腹部超声对肝脏肿块的诊断符合率、诊断效能(阳性预测值、阴性预测值、敏感度、特异度、准确度、约登指数、误诊率、漏诊率等),比较良性及恶性肝脏肿块患者超声参数[血流灌注指数(DPI)、门静脉充血指数(PCI)、阻力比(RR)、肝总血流量(TLBF)]。结果125例肝脏肿块患者经过病理诊断检出恶性33例,良性92例,而经腹部超声检出恶性30例,良性95例。腹部超声诊断肝脏肿块的阳性预测值为93.33%、阴性预测值为94.74%、敏感度为84.85%、特异度为97.83%、准确度为94.40%、约登指数为0.8268、误诊率为2.17%、漏诊率为15.15%。良性患者腹部超声DPI、PCI、RR、TLBF分别为(0.13±0.03)、(6.32±1.31)、(1.35±0.28)、(1215.59±251.99)ml/min,均小于恶性患者的(0.42±0.09)、(8.61±1.80)、(1.49±0.31)、(1345.17±281.66)ml/min,差异有统计学意义(P<0.05)。结论将腹部超声应用在肝脏肿块的诊断和鉴别中具有较好的价值,其诊断和鉴别结果与病理诊断结果差异不大,可以在短时间内为临床工作提供科学性的参考,值得推荐。Objective To study the value of abdominal ultrasonography in the diagnosis of liver mass.Methods All 125 patients with liver mass underwent abdominal ultrasonography and pathological diagnosis.According to the pathological diagnosis results,the coincidence rate and diagnostic efficiency(positive predictive value,negative predictive value,sensitivity,specificity,accuracy,Youden's index,misdiagnosis rate,missed diagnosis rate,etc.)of abdominal ultrasound for liver mass were analyzed.The ultrasound parameters[Doppler perfusion index(DPI),portal vein congestion index(PCI),resistance ratio(RR),total liver blood flow(TLBF)]were compared between benign and malignant liver masses.Results Among 125 patients with liver mass,33 cases were malignant and 92 cases were benign,while 30 cases were malignant and 95 cases were benign by abdominal ultrasonography.The positive predictive value of abdominal ultrasonography was 93.33%,the negative predictive value was 94.74%,the sensitivity was 84.85%,the specificity was 97.83%,the accuracy was 94.40%,and the Youden's index was 0.8268,the misdiagnosis rate was 2.17%,the missed diagnosis rate was 15.15%.The DPI,PCI,RR and TLBF of patients with benign mass were(0.13±0.03),(6.32±1.31),(1.35±0.28)and(1215.59±251.99)ml/min,and those of malignant patients were(0.42±0.09),(8.61±1.80),(1.49±0.31)and(1345.17±281.66)ml/min,and the difference was statistically significant(P<0.05).Conclusion The application of abdominal ultrasonography has a good value in the diagnosis and differentiation of liver mass,and the diagnosis and differentiation results are not much different from the pathological diagnosis results,which can provide scientific reference for clinical work in a short time,and is worth recommending.
