原发性肝癌是常见的恶性肿瘤之一,早期诊断是改善预后和提高生存率的关健。高分辨率的二维超声能检出肝内小于1.0cm占位性病变,但对此作出定性诊断,尤其是小肝癌的明确诊断仍有困难[1]。近年来,利用彩色多普勒(CDF I)、脉冲多普勒(PW)、彩色能量成像(CPA)及三维彩色血管能量成
Primary liver cancer is one of the common malignant tumors, and early diagnosis is the key to improve the prognosis and improve the survival rate. High-resolution two-dimensional ultrasound can detect lesions within the liver less than 1.0cm, but to make a qualitative diagnosis of this, especially the diagnosis of small liver cancer is still difficult to diagnose [1]. In recent years, the use of color Doppler (CDF I), pulsed Doppler (PW), color energy imaging (CPA) and three-dimensional color of vascular energy into
