Elastography, a technology used to measure the elastic properties of a lesion during endoscopic ultrasound (EUS), has been performed for several years now, particularly in Europe and Asia (and seldom in the U.S.), but its value in characterizing pancreatic lesions is still unclear.
In a multicenter, retrospective study, researchers assessed the predictive accuracy of elastography during EUS for diagnosing pancreatic malignancy in over 200 patients with solid, small (≤15 mm) pancreatic lesions.
The stiffness of the target lesion relative to the surrounding pancreatic parenchyma as evaluated by elastography was compared with the final diagnosis obtained by EUS-guided fine-needle aspiration, fine-needle biopsy, or the final surgical pathology in…
