Research Abstract	In this study, we aimed to evaluate the value of contrast-enhanced harmonic endoscopic ultrasonography by using a second-generation contrast agent in pancreatic solid tumors. The enhancement patterns were compared with the final diagnosis of a total of 133 pancreatic solid tumors. The sensitivity, specificity, and accuracy of diagnosis based on combinations of enhancement patterns were respectively, 94%, 89%, 92% for pancreatic carcinoma. We conclude that contrast-enhanced harmonic endoscopic ultrasonography is useful modality for different diagnosis of pancreatic solid tumors.
