Figure 6

Bariatric surgery improves steatosis by multi-echo MRI and Folch estimation. In obese patients who underwent bariatric surgery (n = 56) there was a decrease in the multi-echo MRI fat fraction signal intensities and the Folch value estimated one year after surgery compared to patients who did not receive bariatric surgery (n = 11). A) Representative multi-echo MRI images showing reduction of the fat signal and fat fraction in obese patients after bariatric surgery. In obese patients B) the multi-echo MRI fat fraction signal intensities and C) the Folch estimated one year after surgery were reduced. D) Representative multi-echo MRI images showing no changes of the fat intensity and fat fraction in obese patients who did not receive bariatric surgery. In obese patients who did not undergo bariatric surgery E) the multi-echo MRI fat fraction signal intensities and C) the Folch estimated after one year were not reduced. Dots represent the values of each case. MRI, magnetic resonance imaging.
