The effectiveness of magnetic resonance imaging (MRI) iron corrected T1 in monitoring metabolic dysfunction-associated steatohepatitis in obesity following bariatric surgery and lifestyle modification: a prospective cohort study

Among adults with obesity and MASLD, MRI biomarkers, including cT1, assessed liver health and identified MASH with high accuracy. Bariatric surgery achieved greater reductions in cT1 and PDFF than lifestyle modification, indicating superior improvement in liver health and supporting cT1 for monitoring treatment response.
