Clinical Scorecard: Evaluating the Viability of Neonatal Chest MRI for Bronchopulmonary Dysplasia with a Standard 1.5-Tesla Scanner
At a Glance
Category
Detail
Condition
Bronchopulmonary dysplasia (BPD) in preterm infants
Key Mechanisms
Disrupted alveolar and vascular development causing ventilation/perfusion abnormalities, inflammation, and structural lung abnormalities
Target Population
Preterm neonates with severe BPD and term controls without pulmonary or cardiac comorbidities
Care Setting
Neonatal intensive care unit and imaging facilities with standard 1.5-Tesla MRI scanners
Key Highlights
BPD severity classified by NIH criteria based on supplemental oxygen need at 36 weeks PMA
MRI offers radiation-free, dynamic imaging of neonatal lung structure and function, advantageous over CT
Developed and tested a neonatal chest MRI protocol using standard 1.5-T MRI with a dedicated neonatal chest coil
Guideline-Based Recommendations
Diagnosis
Use NIH criteria for BPD severity classification at 36 weeks postmenstrual age
Consider structural lung imaging primarily for infants with severe BPD
Management
Employ MRI as a non-ionizing imaging modality to assess lung structure and function in neonates
Use feed-and-swaddle technique to perform MRI without sedation in neonates
Monitoring & Follow-up
Perform chest MRI using T2-weighted PROPELLER and proton density-weighted ZTE sequences to detect BPD-related abnormalities
Use grid-based MERGE scoring system adapted for MRI to quantify lung abnormalities
Risks
Avoid MRI in neonates with clinical instability, mechanical ventilation, or congenital cardiovascular/pulmonary abnormalities
Monitor for signs of discomfort during MRI and limit scan duration to 60 minutes
Patient & Prescribing Data
Preterm infants (<28 weeks gestation) with severe BPD and clinically stable term controls
MRI protocols can be implemented on widely available 1.5-T scanners with dedicated neonatal coils, enabling structural lung assessment without sedation or radiation exposure
Clinical Best Practices
Use a dedicated neonatal chest coil and optimized MRI sequences (T2-w PROPELLER and PD-w ZTE) for image quality
Apply feed-and-swaddle technique with immobilization and soothing measures to avoid sedation
Quantify lung abnormalities using the MERGE scoring system adapted for MRI to support phenotyping and personalized treatment
Exclude neonates with contraindications such as clinical instability or congenital anomalies from MRI
Limit MRI scan time to minimize discomfort and monitor infant wellbeing throughout the procedure
