               [Abstract] Objective:The current study aims to establish a risk model for microvascular invasion(MVI)in patients with
                hepatocellular carcinoma(HCC),which is based on radiological characteristics and clinical laboratory data,and to explore the clinical
                application of preoperative alpha⁃fetoprotein(AFP)and gamma⁃glutamyl transferase(GGT)in HCC patients. Methods:Clinical data
                from 479 HCC patients with surgically resection at the First Affiliated Hospital of Nanjing Medical University were retrospectively
                collected to investigate the effects of potentially relevant factors on MVI,and to assess the benefits of serum AFP and GGT on
                improving model predictive performance. Univariate and multivariate logistic regression analyses were used to select variables for the
                final prediction model,and the predictive performance of the model was assessed by area under the receiver operating characteristic
                curve(AUC),calibration curve,and decision curve analysis(DCA). Predictive performance was compared by sensitivity,specificity
                and accuracy analyses. Kaplan⁃Meier curves were applied to assess the probability of patient survival. Results:In a multifactorial
