We developed image analysis tools to evaluate spatial and temporal 3He magnetic resonance imaging (MRI) ventilation
in asthma and cystic fibrosis. We also developed temporal ventilation probability maps to provide a way to describe and
quantify ventilation heterogeneity over time, as a way to test respiratory exacerbations or treatment predictions and to
provide a discrete probability measurement of 3He ventilation defect persistence.
