This research was aimed at investigating the artificial intelligence (AI) segmentation algorithm-based multislice spiral computed tomography (MSCT) in the diagnosis of liver cirrhosis and liver fibrosis. Besides, it was aimed at providing new methods for the diagnosis of liver cirrhosis and liver fibrosis. All patients were divided into the control group, mild liver fibrosis group, and significant liver fibrosis group. A total of 112 patients were included, with 40 cases in the mild liver fibrosis group, 48 cases in the significant liver fibrosis group, and 24 cases who underwent computed tomography (CT) examination in the control group. In the research, deconvolution algorithm of AI segmentation algorithm was adopted to process the images. The average hepatic arterial fraction (HAF) values of patients in the control group, mild liver fibrosis group, and severe liver fibrosis group were  17.59 ± 10.03 %,  18.23 ± 5.57 %, and  20.98 ± 6.63 %, respectively. The average MTT values of patients in the control group, mild liver fibrosis group, and severe liver fibrosis group were  12.69 ± 1.78 S,  12.53 ± 2.05 S, and  12.04 ± 1.57 S, respectively. The average blood flow (BF) values of patients in the control group, mild liver fibrosis group, and severe liver fibrosis group were  105.68 ± 15.57  mL 100 g-1·min-1,  116.07 ± 16.5  mL·100 g-1·min-1, and  110.39 ± 16.32  mL·100 g-1·min-1, respectively. Besides, the average blood volume (BV) values of patients in the control group, mild liver fibrosis group, and significant liver fibrosis group were  15.69 ± 4.35  mL·log-1,  16.97 ± 2.68  mL·log-1, and  16.11 ± 4.87  mL·100 g-1, respectively. According to statistics, the differences among the average HAF, MTT, BF, and BV values showed no statistical meaning. AI segmentation algorithm-based MSCT imaging could promote the diagnosis of liver cirrhosis and liver fibrosis effectively and offer new methods to clinical diagnosis of liver cirrhosis and liver fibrosis.
