Comparison of clinical value and diagnostic rate between barium meal radiography and spectral CT scan in the diagnosis and treatment of gastric cancer and benign gastric tumor

Background: background: to investigate the clinical and diagnostic value of x-ray examination and computed tomography (ct) imaging for gastric cancer (gc) and benign gastric tumors. materials and method: totally 160 patients with gastric tumors treated in baoding first central hospital from october 2016 to december 2017 participated in this study and randomized into the control group and observation group (n=80 per group). the control group received x-ray examination and the observation group underwent ct scan. the diagnostic rate was compared between these two modes. receiver operating characteristic (roc) curve was applied for the evaluation of the diagnostic efficacy of ct quantitative parameters in the observation group. the clinic accordance rate, clinical efficacy and life quality score in the two groups were then compared. results: ct scan is more accurate than x-ray examination in diagnosing gastric cancer and benign tumor (p< 0.05). ct quantitative parameters were of diagnostic value in gastric cancer and benign gastric tumor. their area under curve (auc) was 0.750, 0.696, 0.676, 0.841 and 0.721, respectively. after treatment, the clinical efficacy and functional scales showed improvement in patients examined by ct imaging relative to those examined by x-ray (p<0.05). conclusion: ct scan has a higher diagnostic accuracy than x-ray examination for gastric cancer and benign tumor. selecting appropriate therapy after diagnosing with ct scan is beneficial for the improvement of clinical efficacy.
