ABSTRACT
Objective To assess the 64-slice spiral CT differential diagnosis of the effect on the gastrointesti-nal tract intraepithelial neoplasia and early cancer.Methods A retrospective study of patients with gastric cancer clinical data of 28 patients who underwent surgery and CT scans.CT scans of the tumor in all patients,the stomach wall thickness,tumor extension,N1 and N2 lymph node involvement,liver,peritoneum,lung metastasis.Comparison of spiral CT differential diagnosis of pathological findings and results.Results spiral CT staging was correct in 20 (71.4%).Preoperative CT scan to identify early gastric sensitivity 96.1%,specificity of 100% and an accuracy of 96.4%.Assessment of pathological lymph node involvement sensitivity,specificity,and accuracy were 73.1%, 50.0% and 84.2%.12 patients (42.9%)of the stomach wall thickness 2cm and all patients (100.0%)were serosal involvement.CT detec-tion of T1 and T2 tumors sensitivity and specificity were 57.1% and 90.5%;89.5% and 77.8%.CT assessment of pancreatic invasion of sensitivity,specificity,and accuracy were 100.0%,73.9% and 78.6%.Spiral CT assessment of serosal involvement with/without adjacent organ invasion of sensitivity,specificity and accuracy of 96.4% and reached 96.2%,100.0%.Conclusion Spiral CT in the diagnosis and evaluation of preoperative staging of gastric useful means of early gastric cancer.
