55T Low-field MRI spirometry

Key Points

Low-field MRI spirometry distinguishes lung function differences between active and sedentary individuals.
Preliminary findings indicate regional function evaluation is possible without ionizing radiation.
Healthy volunteers were recruited to assess local lung function through lungs scans.
The study suggests low-field MRI could aid in managing chronic lung pathologies.

Abstract

Motivation: Spirometry measures overall lung function but lacks regional detail. CT scans provide detailed images but involve exposure to ionizing radiation. Low-field MRI offers detailed lung mapping without radiation, making it a promising alternative. Goal(s): Evaluate low field MRI spirometry between active and sedentary healthy individuals. Approach: Healthy volunteers were recruited (2 active and 2 sedentary). Spirometry analysis on 3D lung cine was performed to evaluate the local function of the lung. Results: Preliminary findings indicate that low-field MRI spirometry can distinguish regional lung function differences between active and sedentary individuals, highlighting potential adaptations and the method's potential for non-invasive lung health assessment. Impact: This preliminary study using low-field MRI spirometry reveals potential differences in lung function between active and sedentary individuals. The findings suggest that low-field MRI could serve as a viable, detailed regional lung assessment, potentially benefiting management of chronic lung pathologies.
