Ultrasound elastography was previously used for the diagnosis of breast lesions, prostate cancer and thyroid nodules. However, the value of endoscopic ultrasound elastography for the diagnosis of pancreatic focal masses is not clear for the current moment, as some authors couldn't differentiate benign and malignant pancreatic tumors. Moreover, the intense fibrotic reaction and calcifications in chronic pancreatitis induce strain differences, and it is not clear if elastography is sensitive enough to detect them.
