title: Viability of Oxygen-enhanced Ventilation Imaging of the Lungs Using Ultra-short Echo Time MRI.
abstract: OBJECTIVE
  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 T2*, 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 T2* (-18%).
  
  
  CONCLUSIONS
  Pulmonary images using UTE-MRI are useful for ventilation imaging.
