“…An inflammatory lesion shows a distinctive vessel system of net-like homogeneous vessels with arterial and venous vessels side by side. This is fundamentally different from the neovascularization of an adenocarcinoma, where venous vessels cannot be visualized at all and the arterial vessels are diminished and irregular [ 68 , 76 , 78 , 83 , 85 ]. To differentiate those small vessels, pulsed-wave Doppler is essential and, thus, EUS provides the only technique, to date, that has sufficiently high resolution and the technical capabilities to analyze these vessels.…”
