摘　　要：目的:观察分析超声造影在肝脏肿瘤良恶性鉴别中的意义与实用价值。方法:选取我院2018年3月—2020年6月间60例肝占位性病变病例为研究资料,并对结果进行分析。结果:超声造影检测肝脏恶性肿瘤的灵敏度92.7%、符合率92.9%、约登指数78均明显高于常规超声(χ^(2)=8.8000,9.9068,9.3544,P<0.01);肝脏良性肿瘤行超声造影的始增时间(18.25±3.04)、达峰时间(35.73±8.43)、减退时间(55.42±0.89)、持续强化时间(84.96±1.57)均大于恶性肿瘤(t=5.3487,5.4924,37.0273,82.0934,均P<0.01);而良性肿瘤超声造影峰值强度(19.57±3.43)低于恶性肿瘤(t=4.3096,P<0.01)。结论:超声造影在肝脏肿瘤良恶性鉴别中的应用价值显著。Objective Analyze the contrast-enhanced ultrasound in liver benign and malignant tumor to identify the meaning and practical value.Methods Choose from March 2018 to June 2020,60 cases of liver space-occupying lesions as research materials,and analyze the results.Results Ultrasonic imaging testing the sensitivity of liver malignant tumor,coincidence rate 92.7%to 92.9%,an index of 78 were significantly higher than that of conventional ultrasound(χ^(2)=8.8000,9.9068,9.3544,P<0.01);The initial increase time(18.25±3.04),peak time(35.73±8.43),decrease time(55.42±0.89),and continuous enhancement time(84.96±1.57)for benign liver tumors were all higher than those for malignant tumors(t=5.3487,5.4924,37.0273,82.0934,P<0.01);The peak intensity of ceUS for benign tumors(19.57±3.43)was lower than that for malignant tumors(t=4.3096,P<0.01).Conclusion Contrast-enhanced ultrasound has significant value in differentiating benign from malignant liver tumors.
