Keywords: Lung, Quantitative Imaging, SpirometryThree-dimensional MR spirometry fosters a double paradigm shift upon standard spirometry: from forced to free breathing and from global to local measurements. The technique makes use of voxel-wise flow-volume loops and original biomechanical markers to characterize the regional lung function. Over a diverse adult population, nominal common features showed up throughout 3D MR spirometry parametric maps in healthy volunteers spontaneously breathing in supine and prone positions. Euclidian barycenter and standard deviation maps of local tidal volumes, spontaneous expiratory peak flows, and anisotropic deformation indices are presented here as the ground for a unique atlas of the lung function.
