Abstract：Objective To explore the application value of multi-slice spiral computed tomography(MSCT)in preoperative staging of esophageal cancer.Methods A retrospective analysis was per-formed on the clinical data and MSCT imaging data of 96 patients with esophageal cancer admitted to our hospital between March 2021 and March 2023.Using pathological examination results as the gold stand-ard,the accuracy of MSCT in preoperative staging diagnosis of esophageal cancer was determined.Re-sults Pathological examination showed that there were 18 cases at stage T1,26 cases at stage T2,29 ca-ses at stage T3 and 23 cases at stage T4.There were 52 cases at stage N0 and 44 cases at stage N1-N3.MSCT showed that there were 14 cases at stage T1,23 cases at stage T2,27 cases at stage T3 and 22 ca-ses at stage T4,with diagnostic accuracy of 77.78%,88.46%,93.10%,and 95.65%,respectively.Compared with the golden standard,total diagnostic accuracy rate of MSCT for T staging was 89.58%,and the diagnostic consistency test Kappa=0.779(P<0.05).MSCT showed that there were 40 cases at stage N0 and 36 cases at stage N1-N3,and diagnostic accuracy rates were 76.92%and 81.82%,re-spectively.Compared with the golden standard,total diagnostic accuracy rate of MSCT for N staging was 79.17%,and the diagnostic consistency test Kappa= 0.583(P<0.05).Conclusion MSCT has certain diagnostic value for preoperative staging in patients with esophageal cancer,and could be applied to formulate treatment plans and evaluate prognosis in clinic.
