Functional and morphologic assessment of lung disease is to date performed separately using pulmonary function testing and mostly radiation-based imaging. UTE MRI is a promising tool for radiation-free pulmonary imaging. Pre-existing invasive functional MRI techniques have been transferred to UTE MRI. For non-invasive combined functional and morphologic imaging, radiation-free 3D-UTE MRI acquired in breath-hold and using stack-of-spirals trajectories enables ventilation measurements with high reproducibility for both tidal and deep fractional ventilation.
