Contrast harmonic EUS for the prediction of pancreatic neuroendocrine tumor aggressiveness (with videos)

Contrast-harmonic EUS (CH-EUS) has the ability to depict a tumor microvasculature. Decreased microvascular density has been identified as a factor associated with tumor aggressiveness. We aimed to study the accuracy of CH-EUS for the prediction of pancreatic neuroendocrine tumor (PNET) aggressiveness.
