Hyperpolarized 3He gas MRI was used to assess the SFRP1 knockout mice lung microstructure. SFRP1 knockout mice demonstrated a significant increase in the overall 3He apparent diffusion coefficient value compared to their nave counterparts. Results suggest that this technique can serve as a sensitive and non-invasive in vivo imaging tool for longitudinal studies of development and repair response in pulmonary cells, as well as for the study of lung embryogenesis and monitoring the progression of therapeutic interventions for various lung pathologies.
