RETURN TO ABSTRACT LISTING


Background
Currently under development are paediatric MRE-based scoring systems for Crohn's disease (CD) that will further consolidate the function of MRE in pediatric inflammatory bowel disease (IBD) by implementing standardized analysis, interpretation, and reporting. MRE performs well as an imaging biomarker when compared to endoscopy and clinical biomarkers for evidence of mucosal healing, the current treatment objective. MRE is anticipated to have an even greater impact as an imaging biomarker by demonstrating transmural disease and healing, which cannot be evaluated endoscopically. The purpose of this educational exhibit is to describe the advantages of MRE in pediatric IBD, the requirements for patient preparation prior to imaging, the details about medication (oral contrast agents, IV contrast agents, spasmolitics), standard and advanced sequences utilized in paediatric MRE as well as protocol optimization, the principal MRE findings of UC and/or CD, complications of IBD and related imaging manifestations, disease activity scoring systems, and main points of reporting with diverse and demonstrative cases.

Educational Goals / Teaching Points
To demonstrate the functionality of the MRE technique in the diagnosis of IBD and in the investigation of its complications, thereby enabling more widespread and effective use of MRE.

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
MR enterography (MRE) began in the 1990s as "hydro-MRI" In 2005, Godefroy et al. were among the first to publish the value of MRE in pediatric CD, which is now a reliable diagnostic method for inflammatory bowel disease (IBD) evaluation. Paediatric MRE is now integral to the diagnosis and management of children and adolescents with IBD. Consequently, the use of pediatric MRE has increased over the past decade. This is concurrent with a global increase in childhood-onset IBD, as well as a high prevalence and increasing incidence of IBD in newly industrialized nations, despite a stabilization in the West. Greater awareness of the dangers of ionizing radiation, particularly among the young, and enhanced treatment options for IBD also contribute to the increase in utilization.

Conclusion
The prevelence of pediatric IBD has been increasing. As a safe and reliable method without ionizing radiation, MRE is effective in diagnosis, disease activity scoring, treatment monitoring, and detection of complications. With the possible impact of this educational exhibit, it is hoped that the diagnostic accuracy will be increased by expanding and promoting the use of MRE in pediatric IBD, increasing the quality of examinations, and reviewing the basic imaging findings.
