Epidemiology: Paediatric inflammatory bowel disease is increasing worldwide with an estimated annual incidence in Europe of 23/100000 person years(1). In Scotland, incidence of paediatric IBD of 7.82/100000/year. Incidence is increasing with age at presentation decreasing (mean 11.9 years)(2). Incidence of all subtypes of IBD showed significant increases. Crohn disease (CD) incidence 4.75/100000/year, Ulcerative colitis (UC) 2.06/100000/year and Inflammatory Bowel Disease Unclassified (IBDU) 1.01/100000/year (2). 25% of cases of IBD present in children and young people. Diagnosis is uncommon under 5 years (5% of cases). In...

Paediatric Small Bowel MRI: An approach There ismore than one way to perform small bowel MRI. Even with different scanners from the same manufacturer, sequences that are apparently identical produce images that look different. This poster describes experience with Seimens scanners across 3 Scottish health boards. All are 1.5T magnets. The majority of studies described were performed at the Royal Hospital for Sick Children in Edinburgh using a 1.5T wide bore scanner system (Seimens Espree). When thinking about your protocol consider: Time: Time is money...

SBMRI is the appropriate test for evauation of the small bowel in IBD Paediatric IBD oftenshows with more mucosal and less transmural disease Technique should be optimised for patient group and scanner Large volumes of distending agents are difficult for children to tolerate Diffusion weighted imaging is useful to look for mucosal and transmural disease Most information can be gained using simple sequences on any MRI scanner
