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

Figure 2 Contrast enhancement index decreased with the progression of liver fibrosis. A: Contrast enhancement index (CEI) decreased with the progression of fibrosis, and there was significant difference between patients with Ishak score 0-2, 3-4 and 5-6; B: In patients with modified histology activity index (mHAI) score of 0-4, CEI was lower in patients with Ishak score of 3-4 compared with 0-2; C: In patients with mHAI score of 5-8, CEI decreased with the progression of fibrosis stage; D-F: When the Ishak scores was fixed as 0-2, 3-4 and 5-6 respectively, the value of CEI was not related to the progression of inflammation. ^aP < 0.05; ^bP < 0.001. CEI: Contrast enhancement index; mHAI: Modified histology activity index.
