Abstract:
Objective To observe the value of multi-slice spiral CT enhanced scanning for preoperative TNM staging of gastric cancer compared with postoperative pathology.Methods A total of 219 patients with gastric cancer confirmed by postoperative pathological examination were retrospectively enrolled.The efficacy of spiral CT enhanced scanning for preoperative TNM staging,and its consistency with postoperative pathology were analyzed.Results Multi-slice spiral CT enhanced scanning detected gastric cancer in 214 cases,with detection rate of 97.72％(214/219)and missed diagnosis rate of 2.28％(5/219).Among these 214 cases,the accuracy of spiral enhanced CT for T,N,M staging of gastric cancer was 91.12％(195/214),88.79％(190/214)and 85.98％(184/214),respectively,which was high to extremely high consistent with that of postoperative pathology,with Kappa value of 0.868,0.844 and 0.701,respectively.Conclusion Multi-slice spiral CT enhanced scanning had high value for preoperative TNM staging of gastric cancer.
