Abstract
Objective To explore the application effect of CT three-dimensional reconstruction in the e-valuation of anatomical structure and preoperative staging diagnosis of esophageal cancer.Methods A ret-rospective analysis was conducted on 90 esophageal cancer patients admitted to our hospital from February 2021 to February 2022.The patients were divided into T1,T2,and T3 group,based on different tumor stages.All patients underwent CT three-dimensional reconstruction examination,and the CT three-dimensional recon-struction indicators of patients with different stages were compared.The application value of the above indica-tors in the staging of esophageal cancer patients was analyzed.Results Compared with T1 stage,the tumor volume,length and thickness of esophageal lesions in T2 and T3 stages were all greater,and the differences were statistically significant(P＜0.05);there were no statistically significant difference in tumor volume,length and thickness of esophageal lesion between T2 and T3 stage esophageal cancer;there were no statisti-cally significant difference in tumor CT values among T1,T2,and T3 stage esophageal cancer patients.Corre-lation analysis showed that tumor volume,length and thickness of esophageal lesions were positively correlated with tumor staging in patients(r=0.427,0.435,0.484,0.459,P＜0.05).Conclusion CT three-dimen-sional reconstruction of esophageal cancer can accurately determine the size and location of the lesion,guide preoperative staging,and have guiding significance for the formulation of clinical treatment plans.关键词
