Serum alanine aminotransferase (ALT) has been proposed as a marker of NAFLD, but levels are within the range currently considered "normal" in a large proportion of NAFLD subjects.The aim of the study was to determine the diagnostic accuracy of serum ALT for identifying individuals with NAFLD, using 3-Tesla (T) magnetic resonance spectroscopy (H-MRS).A cross-sectional study was conducted in 129 healthy subjects. Liver triglyceride content was quantified by H-MRS. NAFLD was defined as liver triglyceride content greater than 5.56%.Liver triglyceride content was >5.56% in 79 participants (NAFLD) and lower in the remaining 50 (normal). Serum ALT levels correlated positively with liver triglyceride content (r = 0.58, P 5.56% in 79 participants (NAFLD) and lower in the remaining 50 (normal). Serum ALT levels correlated positively with liver triglyceride content (r = 0.58, P  YR 2017 FD 2017 LK http://hdl.handle.net/10668/11133 UL http://hdl.handle.net/10668/11133 LA en DS RISalud RD Apr 9, 2025
