Methods： SCT findings of 26 cases of Vaters ampullary carcinoma proved surgically and pathologically were analyzed retrospectively in taking water to make the contrast fulling intestine and the focus were scaned by the thin -slice enhancement partially,in which 17 examples were auxiliary by image post - processing technology. Result： The 26 examples patients all have the varying degree the biliary duct system low position obstruction. In which 25 examples CT image can be clear about the mass in the region of raters ampulla,and clearly display the spot, the size as well as periphery the organizational structure relations of the carcinoma. Conclusion： The direct CT signs of carcinoma of vaters ampulla is finding mass in the region of Vaters ampulla, and it is a reliable and effective method to diagnosis and the distinction diagnosis of ampullary Carcinoma with the combination of the spiral CT scanning of thin - slice and image post - processing technology, and it offers important guidance role to its operation treatment.
