The overall image quality of the lung was good to excellent. The bronchi and pulmonary arteries can be visualized up to the the 5th generation and the 7th generation respectively. The whole lung ZTE with free-breathing is feasible and can serve as an alternative method in chest imaging.

Figure 2 A-B. Visibility of lung structures. (A) The posterior segmental bronchus (4th generation) of the right lower lobe (arrow) was well depicted by ZTE. (B) The 7th generation of the pulmonary artery in the right lower lobe (arrow) was well displayed using maximum intensity projection (MIP) by ZTE.
