- W2349922016 abstract "Objective We evaluate the diagnostic value of imaging examinations for patients with periampullary carcinoma.Methods In this study 34 patients suspected to have sufferred from periampullary carcinoma underwent B mode ultrasonography(B us),color doppler imaging (CDI), endoscopic ultrasonography (EUS), ERCP, CT, MRI , Angiography and operative ultrasonography (OUS).Results The detective rates for tumors more than 2cm in diameter were 100% by all imaging methods except for angiography. The tumor detecting rates of EUS, OUS and ERCP were more than 90%(32/34),while of B us, CDI, CT and MRI were about 80%(27/34). Of 10 cases with tumors less than 2cm in diameter, EUS and OUS detected 8,respectively.ERCP plus biopcy detected all of the 10, B us and CDI detected 3,respectively. CT and MRI found 2 and 4 respectively,while none was detected by angiograpy.Conclusions Our study suggested that EUS and ERCP plus biopsy were the most sensitive methods for detecting small tumor, B us was the first choice for scanning the lesions and CDI was helpful in locating the tumor." @default.
