N2 - Purpose: To assess the viability of oxygen-enhanced ventilation images using ultra-short echo time magnetic resonance imaging (UTE-MRI). Methods: We evaluated the oxygen enhancement of the pulmonary T*,2 and pulmonary signals in each TE (0.2, 0.8, 1.4, 2.0 ms) in 21 nonsmokers. Results: The oxygen enhancement of pulmonary signals was the most significant (32%) at the 0.2 ms TE, the second in the pulmonary T*2 (–18%). Conclusions: Pulmonary images using UTE-MRI are useful for ventilation imaging.
