In respiratory self-navigation (SN), static structures, such as the arms or chest wall, may complicate motion detection due to the superposition of signal originating from different tissues. Even if motion detection is successful, the subsequent motion correction may introduce streaking artefacts when applied to static structures. Suppressing signal from those tissues may therefore improve image quality. In this study, we address the hypothesis that SN coronary MRA will benefit from the introduction of an outer volume suppressing "2D-T -Prep", and present results from a moving cardiac phantom and 10 healthy volunteers.
