MR elastograms at 60-Hz and 80-Hz vibration frequencies of two patients. The first patient, a 67-year-old man with chronic hepatitis C, fibrosis stage F3, and necroinflammation grade A1, had stiffness values in MR elastograms at 60 Hz and 80 Hz of 7.82 kPa and 8.23 kPa, respectively (a and b). The ΔG value was calculated as 0.41 kPa. The second patient, an 82-year-old man with chronic hepatitis C, fibrosis stage F3, and necroinflammation grade A2, had stiffness values at 60 Hz and 80 Hz of 5.40 kPa and 6.78 kPa, respectively (c and d). The ΔG value was calculated as 1.38 kPa.
