Clinical value of AEF in the post-processing technique of liver perfusion-like phase III enhanced CT scan in evaluating the degree of liver function impairment in patients with Hepatitis-B cirrhosis

Abstract

Objectives: To investigate the value of CT arterial enhancement fraction (AEF) in the post-processing technique of liver perfusion-like phase III enhanced CT scan in evaluating the degree of liver function impairment in patients with hepatitis B cirrhosis. Methods: The study included 85 patients with hepatitis B cirrhosis admitted to the Department of Radiology, The Affiliated Huai’an Hospital of Xuzhou Medical University from May 2018 to October 2020 were selected as the experimental group, and 71 patients with liver fibrosis during the same period were selected as the control group. All patients underwent routine liver CT phase III perfusion scan, and hepatic AEF (hAEF) and liver/spleen ratio (H/S) were compared between the two groups to analyze the differential value of hAEF and H/S for liver fibrosis and hepatitis B cirrhosis. Patients were divided into the mild group (Grade-A) and the severe group (Grade-B and C) according to Child-Pugh grading. hAEF and H/S values of the two groups were compared, and the evaluation value of AEF on the degree of impairment of hepatitis B cirrhosis was analyzed. Results: hAEF and H/S values of the experimental group were greater than those of the control group (P<0.05), and the AUCs of hAEF and H/S values for distinguishing hepatitis B and cirrhosis were 0.727 (95%CI: 0.650-0.795) and 0.791 (95%CI: 0.718-0.852), respectively. Moreover, hAEF and H/S values of the severe group were greater than those of the mild group (P<0.05), and the AUCs of hAEF and H/S values in evaluating the degree of liver function impairment were 0.746 (95%CI: 0.627-0.834) and 0.770 (95%CI: 0.705-0.928), respectively. Conclusions: AEF boasts the value of differentiating liver fibrosis and cirrhosis, and of evaluating the degree of liver function impairment in patients with hepatitis B cirrhosis. doi: https://doi.org/10.12669/pjms.38.7.5362 How to cite this:Wang N, Sun Z.
