A method for the assessment of pulmonary ventilation and lung perfusion through Magnetic Resonance Imaging (MRI), comprising the steps of: positioning a human subject in an MRI apparatus, delivering a hyperpolarized noble gas to the subject by inhalation, followed by a breath-hold period, during which a bolus of a contrast agent for MRI is injected intravenously, acquiring, during the breath-hold period, at least one MR image of the lungs prior to the bolus intravenous injection and at least one MR image thereafter.
