The use of quantitative contrast- enhanced endoscopic ultrasound in the evaluation of pancreatic neuroendocrine tumors - Can we move from quality to quantity? A proof-of-concept study

Aims Contrast-enhanced EUS (CE-EUS) is a helpful tool for the diagnosis of pancreatic focal lesions, as pancreatic cancer (PC) and pancreatic neuroendocrine tumor (pNEN). Contrast enhancement is usually assessed qualitatively by the endosonographer. Dedicated software has been developed to obtain an unbiased quantitative assessment using perfusion parameters. We evaluated quantitatively the enhancement of pNENs and PC at CE-EUS.
