摘　　要：目的：探讨弥漫性肝癌的超声诊断方法。材料与方法：以超声为主要手段，结合其它影像学方法，进行分析。结果：B超示肝形态饱满，尤以原本硬化、萎缩的右肝为著，血管纹理不清或消失，门静脉系统管腔的无回声区消失，代之以门静脉癌栓（光团状，枯枝状和絮片状）；CDFI示PCT内高频的动脉血流频谱，本文还讨论了PCT与PVT、PCT与气泡的鉴别。结论：门静脉癌柱是诊断弥漫性肝癌最重要的依据。Purpose:To explore on the diagnostic basis of the diffuse type of PHC and evaluate its detectable rate, Materials and methods:B type of Ultrasound provided as the important measure and the other kinds of imaging were totally evaluated. Results:B tyI)e of u1trasound showed the plumpness of liver,especially in the right lobe of the liver that had originally showed as cirrhosis and atrophy. The free echo disappeared and substituted for the echo of parenchyInal tissues:portal cancerous thrombosis (PCT)including 3 tyPes (ball,branch and slice)in the portal vein system. There are hy-Per frequency spectrum of arterious b1ood flow in PCT with CDFI. The paper,otherwize,a1so discussed the differential diagnosis:PCT and portal vein thrombosis (PVT),PCT and bubble in the portal vein.Conclusion:The most important foundation is PCT during diagnosing the diffuse type of PHC.
