Lung MRI is widely used for diagnosis pulmonary disease, there has been continuing interest in the possibility of using MRI to detect the pulmonary lesion. Recent works acquired ventilation defect region using ventilation map. Here we proposed another method, which evaluates ventilation flow map and regional fractional ventilation flow-volume loop using 3D UTE. These methods provide valuable information to evaluate pulmonary ventilation function as well as ventilation map. The potential of methods was demonstrated by different ventilation flow map and regional fractional ventilation flow volume loops in healthy subjects.
