The majority of cases of both pancreatic adenocarcinoma and chronic pancreatitis were hypoenhanced and visual discrimination was not possible. This is the first study about CEH-EUS for the quantitative assessment of uptake after contrast injection which has shown that it can aid differentiation between benign and malignant masses but cannot replace EUS-FNA. Neither tumor stage nor therapeutic management have changed after contrast medium injection during CEH-EUS.
