Research progress of imaging diagnosis of duodenal papillary carcinoma

From the following aspects-duodenal low X-ray imaging, ultrasonography, endoscopic retrograde cholangiopancreatography(ERCP), CT, MRI and magnetic resonance cholangiopancretography(MRCP), this paper will analyze important progress of imaging diagnosis of duodenal papillary carcinoma, as well as advantages and disadvantages of the methods mentioned above. This paper believes that on the basis of using conventional imaging methods, some new methods such as ultrasonography, MRI, CT, ERCP, and endoscopic ultrasonography(EUS) ect. will greatly improve accuracy in the comprehensive treatment on duodenal papillary carcinoma.
