脂肪肝发病率呈逐年增加趋势,而脂肪肝患者时肝细胞内脂肪的聚集以及细胞体积的增加会引起肝微循环的损害。超声作为脂肪肝首先进行的影像学检查方法,简便、易行、无创。本文总结了脂肪肝患者肝静脉频谱、门静脉及肝动脉的超声血流动力学变化,以及超声造影对脂肪肝的研究进展。 The incidence of fatty liver is increasing year by year, while fatty liver cells in patients with liver fat accumulation and cell volume will cause liver microcirculation damage. Ultrasound as the first fatty liver imaging method, simple, easy, noninvasive. This article summarizes the changes of hepatic vein spectrum, portal vein and hepatic artery in patients with fatty liver, and the progress of ultrasound contrast-enhanced hepatic steatosis.
