Generalized Reconstruction by Inversion of Coupled Systems (GRICS) aims at correcting motion artifacts. Since this approach alleviates the breath hold constraint of functional cardiac MRI, cardiac cine imaging using fast spin echo (FSE) sequences should become possible. In this preliminary study, a stack of fat saturated free breathing multi slices FSE cine imaging of the heart has been acquired on one healthy volunteer. The reconstructed cine images display new contrast with T2 weighting and fat saturation. Functional parameters of the left ventricle were computed from manual segmentation clinical software.
