磁共振质子密度脂肪分数(MRI-PDFF)在肝脂肪定量中的应用OACSTPCD
Application of magnetic resonance imaging-proton density fat fraction in liver fat quantification
不同病因的慢性肝病均可出现肝脂肪变性.引起肝脂肪性病变的主要诱因包括慢性病毒性肝炎、胆汁淤积性肝病、酒精和非酒精性脂肪性肝病等.肝脂肪变性初期表现为单纯性脂肪性肝病,继而出现脂肪性肝炎、肝纤维化、肝硬化,甚至肝细胞癌.随着医学影像技术的发展,磁共振质子密度脂肪分数(MRI-PDFF)已在临床广泛应用于脂肪性肝病(FLD)的诊断.MRI-PDFF因具有精确性高及可重复性好的优点,逐步成为FLD无创诊断的"金标准".本文对MRI-PDFF在肝脂肪定量中的临床应用及研究进展进行综述.
Hepatic steatosis can be observed in chronic liver diseases of different etiologies.The main predisposing factors for hepatic steatosis include chronic viral hepatitis,cholestatic liver disease,alcoholic liver disease,and nonalcoholic fatty liver disease.Simple fatty liver disease is the initial manifestation of hepatic steatosis,followed by steatohepatitis,liver fibrosis,liver cirrhosis,and even hepatocellular carcinoma.With the development of medical imaging technology,magnetic resonance imaging-proton density fat fraction(MRI-PDFF)has been widely used in the diagnosis of fatty liver disease(FLD)in clinical practice.MRI-PDFF is gradually becoming the gold standard for the noninvasive diagnosis of FLD due to its high accuracy and good repeatability.This article reviews the clinical application of MRI-PDFF in liver fat quantification and related research advances.
