Figure 1 Upper left quadrant: Ultrasound image of the thickened terminal ileum of a Crohn’s disease patient, with a narrowed lumen and surrounding mesenteric tissue. Upper right quadrant: Appearance of the same ileal segment with strain elastography. Regions of interest (ROIs) can be selected for the quantitative assessment of the strain ratio (see text). Lower quadrant: Strain values of ROI 1 (mesenteric tissue) and ROI 2 (ileal wall) plotted over time for the software to calculate the mean strain ratio (adapted from Fraquelli et al[49]).
