Image registration of lung CT images acquired at different inflation levels has been proposed as a surrogate method to map lung ‘ventilation’. However, this technique requires validation against established ventilation imaging modalities such as hyperpolarized gas MRI. Variations in lung inflation may affect regional lung function as imaged with the two modalities. Here, we evaluate the impact of the lung inflation level during MRI when comparing gas MRI and CT ventilation for a cohort of 7 patients with asthma.
