This is a retrospective cross-sectional research intended to explore the utility of LIVERFASt in the clinical pathways for the detection of liver fibrosis and steatosis in comparison with the Magnetic Resonance Elastography (MRE) and MRct1 fibrosis classification (historical records) and to assess LIVERFASt performance for MR steatosis assessment in an United States adult miscellaneous population with available (historical) MR intracellular fat fraction assessment (ICFF) from a single tertiary US clinic.
1. To assess the correlation and the strength of concordance of LIVERFASt for staging important liver lesions of fibrosis and steatosis against MR liver assessment of clinically significant (≥F2 stage), advanced fibrosis (≥F3 stage) and cirrhosis (F4 stage) (MRE, ct1) and steatosis (MR) in a SLD (MASLD, MetALD) adult US population. 2. To assess the diagnostic performance \[AUROC (95%CI)\] of LIVERFASt for diagnosing important liver lesions of fibrosis, steatosis taking MR-based methods as surrogate gold-standard (MRE for fibrosis assessment and MR for steatosis quantification).
