Free breathing lung MRI techniques were developed for measurement of T2*, inspiratory/expiratory lung volumes, specific ventilation and visualization of the pulmonary vasculature.
Figure 3: Free-breathing 3D UTE images of 4 consecutive slices acquired without fat suppression (a) and with fat suppression (b). Fat around the heart is suppressed in (b) with better visualization of pulmonary arteries and myocardium.
