Imaging modalities in pediatric inflammatory bowel disease

Area of Science:

• Pediatric Gastroenterology
• Medical Imaging
• Inflammatory Bowel Disease

Background:

• Pediatric inflammatory bowel disease (IBD) assessment relies heavily on imaging.
• Accurate disease characterization is crucial for effective treatment optimization.

Purpose of the Study:

• To review imaging modalities for pediatric IBD.
• Determine disease location, phenotype, and severity.
• Optimize treatment strategies through enhanced assessment.

Main Methods:

• Review of current imaging modalities for pediatric IBD.
• Focus on cross-sectional enterography (MRE, CTE).
• Comparison with older techniques like small-bowel follow-through.

Main Results:

• Cross-sectional enterography (MRE, CTE) visualizes lumen, transmural involvement, and extraintestinal manifestations.
• MRE is preferred for pediatric IBD due to lack of ionizing radiation.
• These modalities aid in distinguishing active inflammation from fibrosis and diagnosing complications.

Conclusions:

• Imaging advances have transformed pediatric IBD assessment.
• Cross-sectional enterography is superior to small-bowel follow-through.
• MRE and endoscopy complement each other for disease activity assessment and treatment monitoring.
