FIGURE 9.

Liver stiffness, damping ratio and loss modulus in a healthy normal volunteer (column A) with BMI 21 and an obese patient (B) with BMI 32 and biopsy proven mild inflammation, no ballooning and no fibrosis. MRI showed fat signal fraction of 1.04% in the normal volunteer and 5.7% in obese individual, however liver biopsy showed no steatosis. The mean liver stiffness is borderline elevated (normal cut off is 2.5 kPa) in the obese individual, but damping ratio and loss modulus is significantly elevated and different from the normal healthy volunteer.
