Twenty-five-year-old male patient with Crohn’s disease of the terminal ileum.

<p>A: Coronal MR Enterography images (T2-weighted single-shot turbo spin-echo on the left image; T1-weighted fat saturated, spectrally attenuated inversion recovery after Gadoteric acid administration, on the right image) of a patient with ileitis terminalis demonstrating marked wall thickening of the terminal ileum (white arrow) and mild enhancement after contrast administration (white arrow). B: Longitudinal Contrast enhanced ultrasound (Gray scale ultrasound image, on the right side; Contrast enhanced ultrasound image, on the left side), of the same patient showing wall thickening on Gray scale ultrasound (white arrow) and strong enhancement after Sonovue administration on Contrast enhanced ultrasound (white arrow). C: Endoscopic image of the same patient with an ulcerative ileitis terminalis.</p

<p>Left side: contrast uptake based on increased microvascularization of the terminal ileum in a patient with severe endoscopic disease activity. Right side: contrast uptake of the terminal ileum in a patient with normal endoscopic appearance.</p

Thirty-one-year-old female patient with Crohn’s disease and stenosis of the ileocolic anastomosis after ileocecal resection.

<p>A: Coronal MR Enterography images (T2-weighted single-shot turbo spin-echo on the left image; T1-weighted fat saturated, spectrally attenuated inversion recovery after Gadoteric acid administration, on the right image) of a patient with stenosis (white arrow) and increased enhancement of the ileocolic anastomosis (white arrow). B: Longitudinal Contrast enhanced ultrasound (Gray scale ultrasound image, on the right side; Contrast enhanced ultrasound image, on the left side), of the same patient with a short stenosis of the ileocolic anastomosis (white arrow) and increased enhancement after Sonovue administration (white arrow). C: Endoscopic image of the same patient showing an ulcerative stenosis of the neoterminal ileum.</p
