Abstract：Objective:To evaluate the value of quantitative parameters of contrast-enhanced CT in the evaluation of vascular tumor thrombus in colorectal cancer.Methods:The clinical data of 80 patients diagnosised with colorectal cancer from January 2021 to January 2022 were analyzed retrospectively.All patients underwent enhanced CT examination.The imaging findings of abdominal enhanced CT were observed,the enhanced CT parameters(ΔPMean,ΔPMax,ΔPMin,Tdia and Tvol)of patients with positive and negative vascular tumor thrombus were compared,and the relationship between the enhanced CT quantitative parameters and vascular tumor thrombus were evaluated.Results:The ΔPMean,Tdia and Tvol values of patients with positive vascular tumor thrombus were significantly higher than those of patients with negative vascular tumor thrombus(t=4.166,5.247,5.817;P＜0.05).The quantitative parameters ΔPMean,Tdia and Tvol of enhanced CT were positively correlated with the positive expression of vascular tumor thrombus in colorectal cancer(r=0.480,0.390,0.434;P＜0.05).ROC showed that ΔPMean,Tdia and Tvol had certain diagnostic value in evaluating the vascular tumor thrombus in colorectal cancer,and AUC of the combined evaluation of the three indexes was significantly higher than that of each single index.Conclusion:Quantitative parameter of enhanced CT can be used to screen the presence of vascular tumor thrombus in colorectal cancer with certain reference value in clinical evaluation.
