Elastography techniques, such as two-dimensional magnetic resonance elastography (2D-MRE) are increasingly used for the non-invasive assessment of liver fibrosis in patients with nonalchoholic fatty liver disease (NAFLD). Loomba et al. demonstrate that 3D-MRE (shear wave frequency 40 Hz) had even greater diagnostic accuracy than the commercially available 2D-MRE (shear wave frequency 60 Hz) in diagnosing advanced fibrosis (area under the receiver operator curve, AUROC 0.981 vs. 0.921, P<0. 05) using liver biopsy as reference standard. Despite limitations, MRE serves as an important tool in risk stratification for patients with NAFLD.
弹性成像技术，如二维磁共振弹性成像（2D-MRE），越来越多地用于非酒精性脂肪性肝病（NAFLD）患者肝纤维化的无创评估。Loomba等人证明，在以肝活检为参考标准诊断晚期纤维化时，三维磁共振弹性成像（3D-MRE，剪切波频率40Hz）比市售的二维磁共振弹性成像（2D-MRE，剪切波频率60Hz）具有更高的诊断准确性（受试者操作特征曲线下面积，AUROC分别为0.981和0.921，P<0.05）。尽管存在局限性，但磁共振弹性成像仍是NAFLD患者风险分层的重要工具。
