Usefulness of Contrast Enhanced Harmonic Endoscopic Ultrasound for Pancreatic Cysts

"During the echoendoscopy the image was fixed on the region of interest (pancreatic cyst) and the extended pure harmonic detection mode was selected. 2,4ml contrast enhancement (Sonovue-Bracco Italy) was injected in the right antecubital vein of the participants followed by a flush of 5ml 0.9% saline solution to ensure that the entire quantity of the agent goes in to the blood flow.~After the administration the pancreatic cyst was observed for at least 120 seconds.We followed the enhancing behavior of the cyst wall, the septa and the solid components. Arterial enhancement (contrast uptake) was considered the first 25-30 seconds after injection and the venous phase (wah-out) 30-45 seconds after injection.~EUS-FNA was performed in all patients without contraindications"
