Pediatric MR enterography: technique and approach to interpretation-how we do it

Area of Science:

• Pediatric Radiology
• Gastroenterology Imaging
• Inflammatory Bowel Disease (IBD) Diagnostics

Background:

• Magnetic resonance (MR) enterography is a vital imaging technique for pediatric patients, primarily evaluating inflammatory bowel disease (IBD).
• It offers an alternative to radiation-based imaging, crucial for children and adolescents.
• MRE assesses bowel, mesentery, soft tissues, and extraintestinal manifestations of IBD.

Purpose of the Study:

• To provide radiologists with a systematic approach for reviewing and interpreting pediatric MR enterography in suspected or confirmed IBD cases.
• To illustrate common and uncommon imaging findings associated with pediatric IBD.
• To present a clinically successful pediatric MRE protocol and discuss indications.

Main Methods:

• Review article synthesizing current knowledge and clinical experience.
• Focus on a systematic approach to MRE interpretation in pediatric IBD.
• Inclusion of a standardized pediatric MRE protocol and discussion of clinical indications.

Main Results:

• MRE is effective for initial diagnosis, particularly small bowel Crohn disease.
• It serves as a radiologic biomarker for assessing inflammatory activity and response to therapy.
• MRE identifies disease complications such as strictures, fistulae, and abscesses.

Conclusions:

• MR enterography is an essential, non-ionizing imaging modality for pediatric IBD evaluation.
• A systematic approach and standardized protocol enhance diagnostic accuracy and patient management.
• MRE plays a crucial role in monitoring disease activity, treatment response, and complications.
