1.酒精性脂肪肝:脂肪肝包括弥漫性脂肪肝(均匀性脂肪肝)及限局性脂肪肝(非均匀性脂肪肝)。超声:弥漫性脂肪肝肝脏普遍增大,包膜光滑,肝实质回声增强,呈弥漫性细点状,为亮肝。肝内回声强度随深度而衰减(声衰减现象),肝内血管回声减弱或显示不清。限局性脂肪肝分二型:(1)叶段型:多数病变分布呈叶段型.肝实质内呈现片状回声增强区,常以肝叶段为界或沿门静脉分支长轴分布,边界清楚,无占位效应。(2)
1. Alcoholic fatty liver: Fatty liver includes diffuse fatty liver (Homogeneous fatty liver) and limited fatty liver (Heterogeneous fatty liver). Ultrasound: diffuse fatty liver generally increased liver, smooth envelope, enhanced echogenic parenchyma, was diffuse thin dot-shaped, bright liver. Intrahepatic echo intensity decreases with depth (sound attenuation phenomenon), intrahepatic vascular echo decreased or unclear. Limited fatty liver type: (1) leaf segment type: most of the lesion was leaf segment type .Hepatic parenchyma showed patchy echo enhancement area, often in the liver segment as the boundary or long axis along the portal vein distribution, the border is clear , No placeholder effect.
