Abstract
The small intestine is a long convoluted tube affected by a host of pathologic conditions that can be difficult and challenging to diagnose. The practice of gastrointestinal (GI) radiology has changed dramatically in the last two decades. There was a time when the small bowel follow-through and barium enema were the commonest modalities in the investigation of diseases of the small and large intestine. Enteroclysis was rejuvenated in the 1970s, and defecography was subsequently popularized. Together with the upper gastrointestinal series, these procedures became the primary tools of the gastrointestinal radiologist. MDCT and CT enterography have undesirable potentially nephrotoxic iodine-based contrast medium injection and involving significant ionizing radiation exposure. The aim of work is to review the role of MR enterography in the diagnosis, of small intestinal diseases in children. Recently, new studies were conducted on Magnetization transfer imaging to help detection of fibrosis, and found out that Magnetization transfer ratio correlates with tissue collagen levels and is sensitive to changes in fibrosis over time. This can provide a noninvasive method for determining the fibrotic content of small bowel strictures in Crohn’s disease, and so will greatly affect management decisions. To conclude, although MRE is observed to be a powerful imaging tool for diagnosis of small bowel diseases, assessment of disease activity and detection of their complications, MRE is still currently used in combination with clinical and endoscopic data for assessment of inflammatory bowel disease activity and severity.
