Gadolinium-ethoxybenzyl-diethylenetriamine penta-acetic acid-enhanced magnetic resonance imaging for evaluating fibrosis regression in chronic hepatitis C patients after direct-acting antiviral

Figure 3 Comparison of four noninvasive methods before and after sustained virological response between patients with fibrosis regression or not. A: Value of contrast enhancement index; B: Value of liver stiffness measurement; C: Value of aspartate aminotransferase-to-platelet ratio index; D: Value or Fibrosis-4 in patients with (Red column) and without (Black column) fibrosis regression at baseline and after achieving sustained virological response (SVR). Red column: Patients had fibrosis regression after achieving SVR (n = 7). Black column: Patients didn’t have fibrosis regression after achieving SVR (n = 14). ^aP < 0.05; ^bP < 0.001. CEI: Contrast enhancement index; SVR: Sustained virological response; LSM: Liver stiffness measurement; APRI: Aspartate aminotransferase-to-platelet ratio index; FIB-4: Fibrosis-4.
