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.

L'invention concerne un procédé d'évaluation de la ventilation pulmonaire et de la perfusion de poumon au moyen d'imagerie par résonance magnétique (IRM) qui consiste à positionner un sujet humain dans un appareil d'IRM, à administrer au sujet, par inhalation, un gaz noble hyperpolarisé, suivi d'une durée de blocage de la respiration durant laquelle un bol d'un agent de contraste pour l'IRM est injecté par voie intraveineuse, et à acquérir, lors de la période de blocage de respiration, au moins une image IRM des poumons avant l'injection intraveineuse et au moins une image IRM après.
