High spatial and temporal resolution is desirable for many dynamic contrast enhanced (DCE) MRI applications. Many view sharing methods have been developed to improve both spatial and temporal resolution, but those methods inherently increase temporal footprints, resulting in temporal blurring. In this work, we show a temporal footprint of the view sharing method can be improved by reconstructing the individual subsampled k-space using a novel CS reconstruction while maintaining excellent image quality in a total of 12 DCE MRI patients.
