目的 :探讨彩超对原发性肝癌与肝良性局灶病变鉴别诊断的价值。方法 :对原发性肝癌的 16个肿块 ,2 5例 2 8个肝良性病灶 ,观察其肝内滋养动脉短期内形态变化 ,比较良、恶性肿块动脉直径、显示长度、血流信号级别的变化差异。结果 :1.原发性肝癌 :肿块滋养动脉短期内形态变化大 ,表现为动脉直径增粗、显示长度增加、信号级别加大。两次检查对比 ,定量指标有统计学差异 ;2 .肝良性局灶病变 :病灶血供无动态改变 ,两次检查对比 ,定量指标无统计学差异。结论 :彩超对肝内动脉血流变化的观察在肝肿瘤鉴别中有独到的应用价值
Objective: To investigate the value of color Doppler ultrasonography in differential diagnosis of primary liver cancer and benign liver lesions. Methods: 16 cases of primary hepatocellular carcinoma and 25 cases of benign hepatic lesions of 25 cases were observed. The morphological changes of the nourishing artery in the short term were observed. The diameter, length of the artery, the change of the blood flow signal level difference. Primary liver cancer: Mass nodal artery morphology changes in the short term, manifested as arterial diameter, showing an increase in length, signal level increased. Two check contrast, quantitative indicators have statistical difference; 2. Liver benign focal lesion: no change in the blood supply of the lesion, the two check comparison, quantitative indicators no significant difference. Conclusion: The observation of color Doppler echocardiography in intrahepatic arterial blood flow has unique value in the differential diagnosis of liver tumors
