a Transverse B-mode US scan of the intestinal involved segment shows a deep ulcer with echogenic gas (arrow). The thickened anterior wall is between marks. b CEUS: Transverse US scan in the contrast-specific mode. Measurement of bowel wall vascularity, after second-generation contrast agent injection, in a manually defined ROI, obtaining the brightness-time curves over a period of 40 s. In this case, the absolute and percentage of enhancement increases were 71 and 122, respectively (baseline value 58, maximum value 129)
