Pediatric musculoskeletal MRI: basic principles to optimize success

Area of Science:

• Radiology
• Pediatric Imaging
• Musculoskeletal Imaging

Background:

• Musculoskeletal MR imaging in children presents unique challenges due to developmental changes.
• Ossification and marrow transformation significantly alter the appearance of the growing skeleton on MRI.

Purpose of the Study:

• To provide practical strategies for optimizing pediatric musculoskeletal MR imaging.
• To guide radiologists in interpreting normal developmental skeletal variations.
• To enhance the depiction of abnormalities and improve diagnostic accuracy in pediatric patients.

Main Methods:

• Review of normal musculoskeletal MR imaging appearance across different developmental stages.
• Discussion of optimized imaging parameters, including patient positioning, field of view, and coil selection.
• Evaluation of advanced techniques such as intravenous contrast agents, fat suppression, and parallel imaging.
• Consideration of specific protocols for 3 Tesla (3T) MRI.

Main Results:

• Normal developmental changes in the pediatric skeleton impact MR imaging findings.
• Specific imaging parameters and techniques can significantly improve image quality and diagnostic confidence.
• Advanced tools like contrast and fat suppression are crucial for detecting abnormalities.
• 3T MRI offers potential benefits but requires tailored optimization strategies.

Conclusions:

• Optimizing pediatric musculoskeletal MR imaging requires careful attention to developmental variations and technical parameters.
• Utilizing advanced imaging tools enhances the detection of pathology and improves study efficiency.
• Standardized approaches and specific considerations for 3T MRI are essential for high-quality pediatric musculoskeletal imaging.
