【摘要】 目的讨论原发性小肝癌的超声特征。方法对226例直径≤3.0cm的原发性小肝癌进行二维、三维、彩色多普勒血流显像(CDFI)、超声引导下肝脏穿刺活检综合分析。结果226例小肝癌均有不同回声的超声影象,概括声像图特点将其分为低回声131例(58.0%)、等回声31例(13.7%)、强回声64例(28.3%),对照组与疾病组两者间小肝癌的二维回声无明显差异(P>0.05);而CDFI小肝癌为高阻力血流动力学表现,两者间存在显著性差异(P<0.05)结论超声对小肝癌诊断仍存在一定困难,而超声检查结果进行综合分析对小肝癌诊断有明显的协助作用。更多还原

【Abstract】 Objective To evaluate the value of ultrasound in the diagnosis of primary small liver cancer.Methods A total of 226 patients with small hepatocellular carcinoma (HCC) (≤3.0 cm) underwent two dimensional,three dimensional ultrasound_guided needle liver biopsy.Results There were different degrees of changes shown on sonography in all the 226 patients with HCC,Their ultrasound features were as follows:131(58.0%) cases with hypoechoic,31(13.7%) with isoechoic,64(28.4%) hyperechoic.The control group and studied group of small hepatocellular carcinoma has no significant difference on two dimensional (P>0.05),but peak velocity and resistance index of the arterial blood stream in small hepatocellular carcinoma were higher than those in the control groups (both P<0.05).Conclusions It is still difficult to diagnose the small HCC on 2-D,but 2-D,3-D and color Doppler should be definitely useful in the diagnosis of small HCC.更多还原
