FIG. 8.18 Contrast-Enhanced Ultrasound of the Bowel in Crohn Disease, Subjective and Objective. (A) Two images of contrast-enhanced

bowel, axial view, show the comblike vessels from vascularization of the mesentery and the transmural enhancement of the bowel wall. The adjacent

images on the right are low mean intensity poor detail gray-scale, used for reference. (B) Images are in long axis. A region of interest in the bowel

wall and a subsequent objective time intensity curve allow measurement of the peak enhancement and area under the curve. At the bottom is the

time intensity curve that allows for quantiication of the enhancement parameters. See also Videos 8.6 and 8.7. (A with permission from Wilson S.
