The inflammatory bowel diseases (IBD), Crohn’s disease (CD) and ulcerative colitis (UC) are multifaceted disorders as a consequence of complex interplay between genetic, environmental and immunological factors, leading to a dysregulated immune response of the host intestinal bacteria. In children both the mucosal immune system and the intestinal microflora are still developing. Taken together, it seems that patients with early onset IBD (EO-IBD) are a unique subset within IBD with particular gene defects, phenotypic appearance, drug responsiveness and immune pathology.
Imaging plays a key role in the diagnosis and follow-up of EO-IBD, with MRI enterography being the gold standard in modern IBD practice, largely because of its ability to provide excellent spatial resolution without ionising radiation. EO-IBD can also be elegantly demonstrated on ultrasound and can be used a complimentary imaging tool in both the diagnostic workup and follow up imaging.
The aims of this educational exhibit are to:
(i) Provide a pictorial review of the key imaging finding of EO-IBD as demonstrated on MRI and ultrasound.
(ii) Review the imaging techniques and protocols for MR enterography as applied to EO-IBD.
(iii) Discuss the role of genetic mutations and innate immune defects in the pathophysiology of EO-IBD.

Gadolinium deposition in normal tissues is an increasingly recognized consequence of intravenous gadolinium contrast agents. Children with inflammatory bowel disease (IBD) undergo frequent surveillance imaging with contrast enhanced MR enterography (MRE).
Purpose: To determine the benefit (if any) of IV contrast in evaluation of IBD by MRE.

Ulcerative colitis (UC) and Crohn disease are chronic, immune-mediated, inflammatory disorders of the gastrointestinal tract collectively referred to as inflammatory bowel disease (IBD). As many of 20-25% of patients with IBD initially present in childhood or adolescence, and the incidence of pediatric IBD is increasing. IBD primarily affects the bowel, but other organs can be involved. Nearly one-third of patients will have at least one extra-intestinal manifestation. Some extra-intestinal manifestations, such as that between UC and primary sclerosing cholangitis (PSC), are well-established. Others are less understood and may mimic more common pathology, particularly infection. Therefore, pediatric radiologists must become familiar with these extra-intestinal manifestations and consider the diagnosis of IBD as the etiology for their pathology. Read More

This study compares the performance of a single free-breathing GRASP sequence to a full C-MRE protocol in pediatric small bowel CD. The high k-trans of affected bowel in CD may allow high spatiotemporal GRASP dynamic contrast-enhanced technique to provide comprehensive diagnostic value in CD, especially in patients with limited breath-hold capacity.
