We demonstrate that cardio-respiratory synchronisation can be achieved in conjunction with short TR scans and k-space segmentation to reduce imaging times to below that achievable using standard techniques such as retrospective gating. Our method is generally applicable to other short TR scan modes requiring cardio-respiratory synchronisation. Images of the mouse heart, lung and liver are presented for the b-SSPF scan mode.
