Magnetic resonance imaging of the pediatric mediastinum: updates, tips and tricks

Area of Science:

• Medical Imaging
• Pediatric Radiology

Background:

• Pediatric mediastinal magnetic resonance imaging (MRI) is complex.
• Challenges include small patient size, diverse pathologies, motion artifacts, and sedation needs.
• These factors complicate accurate diagnosis for practicing radiologists.

Purpose of the Study:

• To provide a practical review of pediatric mediastinal MRI.
• To emphasize diseases where MRI is the primary imaging modality.
• To address mediastinal processes where MRI serves as a secondary problem-solving tool.

Main Methods:

• Focus on motion-reduction techniques.
• Incorporate pediatric-specific considerations.
• Review of primary and secondary applications of MRI in pediatric mediastinal pathology.

Main Results:

• Special attention to motion reduction and pediatric considerations improves diagnostic accuracy.
• MRI can be the sole imaging modality for certain pediatric mediastinal diseases.
• MRI effectively solves problems in other mediastinal conditions.

Conclusions:

• Optimized MRI techniques enable accurate and timely diagnosis in pediatric mediastinal imaging.
• Knowledge of pediatric-specific factors is crucial for successful interpretation.
• MRI can reduce the need for multimodality imaging in the pediatric population.
