Accessible pediatric neuroimaging using a low field strength MRI scanner

Area of Science:

• Neuroscience
• Medical Imaging
• Developmental Biology

Background:

• Magnetic resonance imaging (MRI) is crucial for understanding child neurodevelopment.
• High costs of conventional MRI limit studies, especially in low- and middle-income countries (LMICs).
• Limited data exists on pediatric brain development in LMICs due to resource constraints.

Purpose of the Study:

• To assess the feasibility of low-field MRI for pediatric neurodevelopmental studies.
• To evaluate a low-cost, accessible 64mT MRI scanner for pediatric imaging.
• To replicate brain volume estimates and developmental trajectories using low-field MRI.

Main Methods:

• Collected pediatric MRI data from children aged 6 weeks to 16 years using a 64mT scanner.
• Compared results with established 3T MRI data for brain volume estimation and developmental trajectories.
• Focused on demonstrating routine low-field pediatric neuroimaging.

Main Results:

• Presented the first pediatric MRI data from a low-cost 64mT scanner.
• Successfully replicated brain volume estimates and developmental trajectories typically derived from 3T MRI.
• Preliminary results indicate viability of low-field MRI for pediatric neuroimaging.

Conclusions:

• Low-field MRI systems show potential as a cost-effective complement to high-field systems.
• This technology may expand neurodevelopmental research globally, particularly in LMICs.
• Further research can enhance understanding of neurodevelopmental impacts of environmental factors in diverse populations.
