A double echo ultra short echo time (UTE) acquisition for respiratory motion‐suppressed high resolution imaging of the lung

Magnetic resonance imaging is a promising alternative to computed tomography for lung imaging. However, organ motion and poor signal‐to‐noise ratio, arising from short T2* , impair image quality. To alleviate these issues, a new retrospective gating method was implemented and tested with an ultra‐short echo time sequence.
