ACR Appropriateness Criteria® Crohn Disease-Child

Area of Science:

• Gastroenterology
• Radiology
• Clinical Guidelines

Background:

• Crohn disease (CD) is a chronic gastrointestinal inflammatory condition with variable clinical courses.
• Diagnosis and management of CD rely on integrating clinical, laboratory, endoscopic, histological, and imaging data.
• Imaging plays a crucial role in diagnosing CD, assessing disease activity, monitoring progression, and guiding treatment.

Framework:

• The American College of Radiology (ACR) Appropriateness Criteria provide evidence-based guidelines for medical imaging.
• These guidelines are developed and annually reviewed by a multidisciplinary expert panel.
• Methodologies like RAND/UCLA and GRADE are used to assess the appropriateness of imaging procedures for specific clinical scenarios.

Implementation:

• The document addresses four key variants of imaging use in Crohn disease.
• These include initial imaging for suspected CD, imaging during acute exacerbations, disease surveillance and monitoring, and imaging for perianal fistulizing disease.
• Recommendations are based on extensive literature review and expert consensus, supplemented by expert opinion when evidence is limited.

Implications:

• Appropriate use of imaging can significantly improve diagnostic accuracy and patient management in Crohn disease.
• These guidelines aim to optimize the selection of imaging modalities for various clinical situations.
• The recommendations support evidence-based practice and enhance the effective use of diagnostic imaging in pediatric and adult Crohn disease patients.
