Comment on: Liver Fat Quantification and Steatosis Grading in Fatty Liver Disease by Magnetic Resonance Imaging: Systematic Review and Meta‐Analysis—Reference Standard Ambiguity: Biopsy Versus MRS—Why Pooling These Standards Dilutes MRI‐FF Diagnostic Accuracy Estimates
Key Points
The accuracy of liver fat quantification hinges on the reference standards used, mainly biopsy and magnetic resonance spectroscopy.
Key evidence indicates that pooling reference standards may dilute the diagnostic accuracy estimates for MRI in diagnosing fatty liver disease.
Systematic review and meta-analysis approach were utilized to investigate the discrepancies in steatosis grading between different methods.
Findings underscore the need for clear reference standards to improve MRI's diagnostic utility for liver fat quantification.
