Figure 1.
Magnetic resonance (MR) color elastogram with a 0 to 8 kPa scale in case 1 demonstrates increased liver stiffness with red and orange regions that show increased stiffness values instead of blue and purple regions with lower stiffness values. In the quantitative analyses, mean liver stiffness values were observed as 5.25 kPa before treatment (A) and 3.6 kPa after treatment (B). Of note, red and orange regions are decreased in the follow-up MR elastogram. Interpretation of MR elastography results: 2.5 kPa = normal; 2.5 to 3.0 kPa = normal or inflammation; 3.0 to 3.5 kPa = stage 1 to 2 fibrosis; 3.5 to 4 kPa = stage 2 to 3 fibrosis; 4 to 5 kPa = stage 3 to 4 fibrosis; and >5 kPa = stage 4 fibrosis.
