Contrast-Enhanced Endoscopic Ultrasonography for Pancreatic Tumors

Figure 1

Evaluation of vascular pattern by contrast-enhanced endoscopic ultrasonography (CE-EUS). A representative case of tumors with hypervascular pattern: pancreatic lesion was detected as a low echoic lesion (arrow) with B-mode EUS (a). CE-EUS detected a pancreatic lesion with hyperintensity of enhancement (arrow) as compared to that of surrounding pancreatic tissue (b). A representative case of tumors with isovascular pattern: pancreatic lesion was detected as a low echoic lesion (arrow) with B-mode EUS (c). CE-EUS detected a pancreatic lesion with isointensity of enhancement (arrow) as compared to that of surrounding pancreatic tissue (d). A representative case of tumors with hypovascular pattern: pancreatic lesion was detected as a low echoic lesion (arrow) with B-mode EUS (e). CE-EUS detected a pancreatic lesion with hypo-intensity of enhancement (arrow) as compared to that of surrounding pancreatic tissue (f).
