Magnetic resonance enterography (MRE) was the most common modality for small bowel imaging across UK centres, comprising 13,099/18,784 (69.7%) investigations. There was regional variability in other modalities used, with 5 centres performing 81% of all intestinal ultrasound, and 3 centres performing 65% of all small bowel follow-through. Compared to outpatients, inpatients with suspected IBD were significantly more likely to be imaged with techniques imparting ionising radiation whether scanned either in-hours (p = 0.005) or out-of-hours (p < 0.001).
