Study of TNM Staging of Gastric Carcinoma with Triphase Incremental Helical CT / 实用放射学杂志

ABSTRACT

Objective To evaluate the diagnostic value of TNM staging of gastric carcinoma with triphase incremental helical CT.Methods Triphase incremental helical CT of the stomach with water-filling method were performed in 101 patients with gastric carcinoma.Results (1)The accuracy of T-staging,N-staging and TNM staging was 81.8%,72.9% and 80.2% respectively.(2)Demonstrating multilayered structure of the normal gastric wall in the arterial parenchymal-phase was advantageous to improve the accuracy of estimating the depth of tumor invasion (?
