Free-breathing 3D MRI techniques are applied to explore the impact of COVID-19 in adults. Single echo non-fat suppressed Ultra-short TE (UTE) was utilized for automatic segmentation of lung, Multi-echo UTE with fat suppression was used to obtain T2* maps, and UTE with Time-Spatial Labeling Inversion Pulse (Time-SLIP) allowed to visualize pulmonary vasculature.
