Fig 1.
Representative example of a pancreatic adenocarcinoma with hypoenhancement.
Conventional endoscopic ultrasonography (left) shows a heterogeneous hypoechoic area without a clear margin at the pancreas head. Contrast-enhanced harmonic endoscopic ultrasonography (right) indicates that most of the area is hypovascular and the remaining area is hypervascular compared to the surrounding tissue. An irregular margin is visible.
Fig 2.
Representative example of focal pancreatitis with hyperenhancement.
Conventional endoscopic ultrasonography (left) shows a slightly hypoechoic area without a clear margin at the pancreas head. Contrast-enhanced harmonic endoscopic ultrasonography (right) indicates that enhancement in this area is higher than in the surrounding tissue, and a margin is clearly visible.
Fig 3.
Representative example of a pancreatic neuroendocrine tumor with hyperenhancement.
Conventional endoscopic ultrasonography (left) shows a hypoechoic mass with a clear margin at the pancreas body. Contrast-enhanced harmonic endoscopic ultrasonography (right) indicates that the mass has a hyperenhancement compared to the surrounding tissue.
