Body mass index and its effects on liver fat content in overweight and obese young adults by proton magnetic resonance spectroscopy technique

Figure 1 Proton magnetic resonance spectroscopy technique was used for liver fat assessment. Water peak was shown occurring at 4.72 ppm, peaks in fat for CH₃ occurred at 0.9 ppm, and CH₂ peaked at 1.3 ppm and 2.1 ppm. A: Magnetic resonance imaging axial image of abdomen show voxel localization in right lobe liver for liver fat content quantification. B: Representative fitted proton magnetic resonance spectroscopy spectrum of right lobe liver.

Figure 2 Pearson correlation coefficient (r) and data distribution by sex in each group between body mass index, waist-to-hip ratio, glycosylated hemoglobin, and liver fat content as measured by proton magnetic resonance spectroscopy. BMI: Body mass index; HbA1c: Glycosylated hemoglobin; LFC: Liver fat content; W/H ratio: Waist-to-hip ratio.

Figure 3 Pearson correlation between glycosylated hemoglobin (circle in red, lower x axis), fasting plasma glucose (star in blue, upper X axis), and liver fat content as measured by proton magnetic resonance spectroscopy. BMI: Body mass index; FG: Fasting plasma glucose; HbA1c: Glycosylated hemoglobin; LFC: Liver fat content.
