Accuracy of Imaging Techniques in Diagnosing Steatohepatitis and Fibrosis in NAFLD Patients

liver ultrasound (US), including shear wave elastography (SWE) with liver stiffness measurement and US- fatty liver indicator (US-FLI), and a multiparametric unenhanced liver magnetic resonance examination including MR spectroscopy (MRS), Proton Density Fat Fraction (PDFF) and T2\* measurement with Multiecho technique, T1 mapping with Inversion Recovery method, and Intravoxel Incoherent Motion diffusion weighted imaging (IVIM-DWI), measuring different parameters.
