Abstract

Fatty liver diseases represent the most common chronic liver diseases today. Therefore, the diagnostics of fatty liver is of great importance. Sonography is the most used imaging method in daily clinical practice for its availability and good diagnostic performance. But there are limitations in lower sensitivity in mild steatosis and in subjects with more severe obesity. Sonographic findings of fatty liver include higher echogenity of liver parenchyma and attenuation of ultrasound waves in deeper parts of the liver. Furthermore, there are some other advanced methods for semiquantitative and quantitative assessment of the amount of the liver fat. Many of them are based on acoustic signal attenuation assessment. The most broadly used is a CAP (controlled attenuation parameter) feature of FibroScan, which can assess fatty liver without classic ultrasound examination. Thera are also special MR based techniques - MR spectroscopy and PDFF (protein density fat fraction) which allow liver fat quantification with high precision and can be used as a reference standard.

脂肪肝的诊断方法。
脂肪肝是当今最常见的慢性肝病。因此,脂肪肝的诊断具有十分重要的意义。超声检查是临床上应用最广泛的影像学检查方法,具有实用性和较好的诊断效果。但在轻度脂肪变性和重度肥胖患者中,敏感性较低存在局限性。脂肪肝的超声表现包括肝实质高回声和肝深部超声衰减。此外,还有一些先进的半定量和定量评价肝脏脂肪量的方法。其中许多是基于声信号衰减评估。使用最广泛的是纤维扫描的CAP(受控衰减参数)特征,它可以在没有经典超声检查的情况下评估脂肪肝。还有一些特殊的基于MR的技术- MR光谱和PDFF(蛋白质密度脂肪分数),它们可以高精度地定量肝脏脂肪,并可作为参考标准。
