摘要/Abstract

摘要： 非酒精性脂肪肝目前是成人及儿童慢性肝病最常见的原因,其发病率正在逐年上升。以非酒精性脂肪肝、非酒精性脂肪肝炎及脂肪性肝硬化的疾病谱强烈危害到人类的生命健康及寿命,且非酒精性脂肪肝已被指出与多种慢性疾病相关。正确意识并诊断该病已成为临床所需要重视的问题,但目前该病的诊断金标准仍为穿刺病理活检,影像学检查因其无创、重复性强等优点而利于患者的诊断及随访观察。就超声、CT及磁共振技术定性定量诊断非酒精性脂肪的研究进展予以阐述。

Abstract: Non-alcoholic fatty liver disease(NAFLD)is the most common cause of chronic liver disease in adults and children. NAFLD, nonalcoholic steatohepatitis(NASH)and fatty liver cirrhosis have been associated with a variety of chronic diseases. Correct awareness and diagnosis of the disease has become a problem that clinical needs to pay attention to, but the gold standard for the diagnosis of the disease is still biopsy, imaging examination because of its non-invasive, repeatability and other advantages and conducive to the diagnosis of patients and follow-up observation. In this paper, the advances on the qualitative and quantitative diagnosis of nonalcoholic fat by ultrasound, CT and MR are reviewed.

Key words: non-alcoholic fatty liver disease, ultrasound, real-time tissue elastography, dual energy spectral CT, magnetic resonance imaging, magnetic resonance spectroscopy, iterative decomposition of water and fat with echo asymmetry and least squares estimation quantification sequence, diffusion-weighted imaging
