. 1H magnetic resonance imaging has had limited value in the lung due to short T2*in spite of research showing that functional information can be obtained with oxygen enhanced MRI [1]. Recently, advances in ultra-short TE (UTE) pulse sequences [2] have begun to provide the ability to image the lung parenchyma. In this work we evaluated whether UTE MRI could be used for oxygen-enhanced 3D imaging of human lungs during free breathing
