MR imaging of the chest is challenging due to the low proton density, the short T2* of the lungs and cardiorespiratory motion. Many patients suspected of pulmonary embolism are short of breath, which can limit the utility of breath-held techniques. Free-breathing ultrashort echo time (UTE) approaches (TE < 0.10 ms) help to overcome some of these difficulties. In this prospective pilot clinical study, we demonstrate that UTE provides better overall depiction of chest structures when compared to MRA. We conclude that UTE is complementary to MRA of the chest in the analysis of both vascular and non-vascular thoracic structures.
