Figure 2 B-mode intestinal ultrasound. A: Terminal ileal stricture; B: Prestenotic dilation; C: Dual mode scanning before injecting intravenous contrast for contrast enhanced ultrasound; D: Peak enhancement after contrast injection; E: Wash out during contrast enhanced ultrasound; F: Shear wave elastography showing stiffness of 42.1 kPa; G: Colonoscopic view of stricture; H: Real time elastography showing a soft stricture showing predominantly red and green areas; I: Small intestinal contrast ultrasound showing mid ileal stricture with enteroliths; J: Ileal stricture with prestenotic dilation on small intestinal contrast ultrasound seen using curvilinear probe (1-7 MHz); K: Same stricture seen with linear probe (2-9 MHz).
