Clinical Scorecard: Imaging Guidelines for Common Pediatric Lung Conditions: Recommendations from the European Society of Paediatric Radiology

At a Glance

Key Highlights

• Systematic assessment of pediatric chest radiographs includes evaluation of lung volume, focal abnormalities, mediastinal contours, cardiac silhouette, airways, presence of pneumothorax or effusions, and line/tube positioning.
• Chest radiograph and lung ultrasound are first-line imaging modalities; chest CT is reserved for complex cases; chest MRI is used for chest wall/mediastinal lesions and functional imaging to minimize radiation exposure.
• Imaging protocols and techniques must be age-adapted, with special considerations for sedation, positioning, and respiratory maneuvers to optimize image quality and diagnostic accuracy.

Guideline-Based Recommendations

Diagnosis

• Collect detailed clinical history including gestational age, timing of imaging, delivery method, presenting symptoms, ventilation type, and fetal ultrasound findings.
• Use chest radiograph and lung ultrasound as initial diagnostic tools for pediatric pulmonary diseases.
• Reserve chest CT for complex cases requiring detailed anatomical assessment.
• Use chest MRI for chest wall and mediastinal lesions, repeated imaging to reduce radiation, and functional studies such as ventilation and perfusion.

Management

• Interpret radiographs systematically to identify disease patterns and complications such as pneumothorax and pulmonary interstitial emphysema.
• Apply age-appropriate imaging protocols including high-pitch fast CT for children under 5 years to reduce motion artifacts and radiation.
• Use sedation or anesthesia as needed for MRI in children aged 6 months to 6 years to ensure image quality.

Monitoring & Follow-up

• Monitor radiological changes post-treatment, e.g., improvements after surfactant administration in RDS.
• Use dynamic MRI techniques for functional assessment of central airways and diaphragm motion.
• Perform inspiratory and expiratory CT scans in cooperative older children to detect airway obstructions.

Risks

• Radiation exposure from repeated CT imaging necessitates use of MRI and ultrasound when possible.
• Barotrauma from mechanical ventilation can cause pulmonary interstitial emphysema and pneumothorax.
• Challenges in obtaining high-quality images in younger children require careful technique and sometimes sedation.

Patient & Prescribing Data

Preterm neonates, infants, and children with suspected or confirmed pulmonary disease

Radiological grading of respiratory distress syndrome guides severity assessment; imaging findings inform management decisions including ventilation strategies and surfactant therapy.

Clinical Best Practices

• Systematically evaluate all key radiographic features in pediatric chest imaging to avoid missed diagnoses.
• Tailor imaging modality choice and protocols to patient age, clinical question, and need to minimize radiation exposure.
• Incorporate clinical history and presentation details to improve differential diagnosis accuracy.
• Use dynamic and functional imaging modalities when available to enhance assessment of airway and lung function.
• Ensure multidisciplinary collaboration between radiologists, neonatologists, and pediatricians for optimal patient care.
