In a lung therapy method, hyperpolarized gas is administered for one breath to a subject, and a magnetic resonance scan of at least one lung of the subject is conducted. The data obtained from the scan are evaluated, specifically to determine the extent and distribution of infusion of hyperpolarized gas in the lung, as an indication of the alveolae in the lung which are open. Based on the evaluation of the data obtained in the magnetic resonance scan, a determination is made as to whether administration of a surfactant is necessary in order to improve opening of the lung. If a surfactant is administered, the procedure can be repeated to obtain an updated dataset, which can be evaluated to determine whether the administered surfactant has been effective.
