Motivation: Major limitation of lung MRI is irregular respiratory motion which can be overcome by the retrospective non-uniform self-gating approach.
Goal(s): Additionally, achieving a sufficient temporal resolution is crucial for clinical evaluations and the assessment of physiological parameters.
Approach: This abstract presents a single-petal rosette UTE trajectory in combination with non-uniform self-gating as compared to a 1D image-based, retrospective self-gating approach and furthermore, to the radial UTE trajectory.
Results: SPR combined with nuSG proves suitable and especially benefits from the improved high temporal resolution images that image-based self-gating builds on.
Impact: This abstract presents the suitability of the non-uniform self-gating approach for 2D lung imaging using single petal rosette trajectory.
