Typical endoscopic ultrasonography (EUS) strain elastography images of pancreatic lesions. (A) A representative example of pancreatic cancer. A pancreatic lesion was detected as a low echoic lesion (arrowhead) on conventional EUS (left). EUS strain elastography detected a pancreatic lesion with a heterogeneous blue pattern (arrowhead) compared with that of surrounding pancreatic tissue (right). (B) A representative example of inflammatory mass. A pancreatic lesion was detected as a low echoic lesion (arrowhead) on conventional EUS (left). EUS strain elastography detected a pancreatic lesion with a heterogeneous blue-to-green pattern (arrowhead) compared with that of surrounding pancreatic tissue (right). (C) A representative example of neuroendocrine tumor. A pancreatic lesion was detected as a low echoic lesion (arrowhead) on conventional EUS (left). EUS strain elastography detected a pancreatic lesion with a homogeneous blue color (arrowhead) compared with that of surrounding pancreatic tissue (right).
