随着高品质超声仪的普及,尤其是近几年超声造影技术的临床应用,大大提高了肝内微小占位病变(直径≤2cm)的检出率及病变性质诊断的敏感性和特异性。同时,超声技术在微小肝癌的诊断及局部微创治疗和手术中具有重要的作用。本文对此作一介绍。1二维超声肝脏微小占位病变因其病理性 With the popularization of high-quality ultrasound system, especially in recent years, the clinical application of ultrasound contrast technology, greatly improving the detection rate of small intrahepatic lesions (diameter ≤ 2cm) and the sensitivity and specificity of the diagnosis of the nature of the lesion. At the same time, ultrasound technology in the diagnosis of small liver cancer and minimally invasive treatment and surgery has an important role. This article gives an introduction. A two-dimensional ultrasound liver lesions due to its small pathological lesions
