脂肪肝是由多种因素引起的肝脏内脂肪含量增多,脂肪过度沉积于细胞内超过正常范围时,从而导致肝脏形态和功能改变的一种疾病。随着人们生活水平的提高和膳食结构的改变,脂肪肝的发病率逐年增高。病理上肝内脂肪贮量占肝重5%以上或组织学表现为30%以上的肝细胞脂肪变性即可诊断为脂肪肝,但不易操作。由于超声技术对组织界面声阻抗差有较高的敏感性,目前已成为脂肪肝检查的重要首选方法。随着经济的发达,人们健康体检意识的增强和超声检查手段的普及,被发现患脂肪肝的患者也在增多。因脂肪肝早期无明显临床表现,但晚期可进展成肝硬化,所以早发现早治疗是必要的。现将文登整骨医院2007年3～12月对文登市退休 Fatty liver is caused by a variety of factors, the liver fat content increased, excessive deposition of fat in the cells over the normal range, resulting in a change in liver morphology and function of a disease.

Ultrasound has a high sensitivity to acoustic impedance differences at the tissue interface and has become an important and preferred method for fatty liver examination. With the development of economy, people’s awareness of physical examination is enhanced and the popularity of ultrasonic examination means that patients with fatty liver are also found to be increasing.
