The spatial resolution of in vivo lung imaging is limited by motion in thoracic cavity. In order to establish imaging protocol with constant repetition time for mice lung MRI, the potential of two different acquisition approaches, retrospective self gating and signal averaging, were investigated and compared to cardio-respiratory gating acquisition.
