Primary Outcome
Correlation between (1) spontaneous expiratory volume in 1 s (SEV1) and tidal volume (TV) and (2) FEV1 and FVC,Difference of expiratory volume in 1 s (SEV1) and tidal volume (TV) between the left and right lungs,Difference in expiratory volume in 1 s (SEV1) and tidal volume (TV) for the anterior-posterior, inferior-superior and medial-lateral lung regions
Summary
Spirometry is now the gold standard technique for assessing lung function in humans. From the
 shape of a flow-volume curve measured while the patient, trained by the practitioner,
 performs forced breaths, the forced vital capacity (FVC) and the forced expiratory volume in
 one second (FEV1) can be deduced and the pulmonologist is able to detect and characterize
 respiratory diseases as well as to evaluate current treatments. This technique is
 non-invasive and simple. It is widely available, robust, reproducible and sensitive to
 intervention. However, it requires proactive cooperation from the patient and only measures
 global pulmonary ventilation, without locoregional information.
 
 An innovative strategy and an original study framework have been developed in the BioMaps
 laboratory to establish local maps of flow-volume curves across the lung and to jointly
 analyze ventilatory function and mechanical behavior at any point in the lung: 3D magnetic
 resonance spirometry. As respiratory mechanics fundamentally supports ventilatory function,
 this technique should open a new avenue to non-invasively explore lung function while
 providing a better diagnosis of regional lung diseases.
