- Correlation between time-intensity curves of dynamic ultrasound and dynamic Magnetic Resonance Imaging [ Time Frame: up to 1 week ]Time intesity curves are obtained using intra venous contrast agents during Magnetic Resonance Imaging scans and Ultrasound examination of the small bowel
- Correlation between elastography scans of Magnetic Resonance Imaging and Ultrasound of the small bowel [ Time Frame: up to 1 week ]
- Correlation between Doppler Score and Contrast Enhanced Ultrasound Score [ Time Frame: up to 1 week ]Doppler score (Limberg score) and Contrast Enhanced Ultrasound score are obtained during the same scanning procedure
- Correlation between greatest bowel wall thickness and disease activity measured in Ultrasound and Magnetic Resonance Imaging [ Time Frame: up to 1 week ]
- Correlation between Ultrasound score and Faeces Calprotectin [ Time Frame: up to 2 months ]
- Correlation between Crohns disease activity index and Ultrasound score [ Time Frame: up to 2 months ]

Patients with Crohns Disease referred to referred to a Magnetic Resonance Imaging Scan.
Crohns disease (CD) is a lifelong chronic Inflammatory Bowel Disease (IBD) normally with an early debut. It requires continuous evaluation with either endoscopy, Magnetic Resonance Imaging (MRI), Computed Tomography (CT) or Wireless Capsule Endoscopy (WCE). These methods are either expensive, invasive or with uses radiation. Therefore UltraSound (US), as a cheap, fast and well tolerated examination of the small bowel are tested against the the validated MRI examination of the small bowel. Both examinations are using intra venous (i.v.) contrast agents. Obtained results are compared to disease activity.
Hypothesis is, that dynamic US is comparable to dynamic MRI and therefore should be the first examination of choice in evaluating patients with CD.
This study is a pilot study only.
