Objective to evaluate multislice CT (MSCT) scan and enhanced scan in the diagnosis of gastric schwannoma clinical value. Methods Selection methods from January 2013 to October 2013 of our hospital 20 patients with gastric schwannoma as the research object, a retrospective analysis of gastric schwannoma MSCT scan and enhanced scan performance, including the lesion site, tumor size, strengthening the characteristics and the mucous membrane contact surface ulcers, etc., to compare tumor diameter of MSCT scan and enhanced scan, CT value and diagnostic efficiency, at the same time analysis the differential diagnosis of gastric schwannoma. Results MSCT scan of gastric schwannoma is the origin of the stomach wall round or class round mass, single, clear boundary, uniform texture, see lesions are different degree of internal capsule, progressive persistent strengthening MSCT enhanced scan, the areas of capsule of not reinforced, mild arterial enhancement and portal phase moderately strengthening, substantial improved significantly; MSCT enhanced scanning stage arterial, portal, the essence of the tumor diameter [(4.12+0.23) cm, (5.06-0.08) cm, (5.11-0.02) cm], CT value [(53.26+1.06), (70.15-0.14), (70.16-0.32)] are higher than MSCT scan (P<0.05). The accuracy of MSCT enhanced scan in the diagnosis of gastric schwannoma significantly higher than the 95.00% 72.22% MSCT scan (P<0.05), and sensitivity, specific degrees is no significant difference (P>0.05). The morphology of gastric schwannoma, increase after strengthening degree, whether in retroperitoneal lymph node enlargement/transfer can serve as a gastric stromal tumors and gastric lymphoma the differential diagnosis of gastric cancer. Conclusion MSCT can accurately show the morphology of gastric schwannoma, parts, and the relationship between internal structure and adjacent structure, through enhanced scan can improve the diagnostic accuracy, is helpful to make correct diagnosis.
