0.55T Low-field MRI spirometry

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.
