In recent years parallel imaging and dynamic undersampling have become routinely available in clinical cardiac MRI. However, these techniques have been slow to translate to the pre-clinical setting. In this abstract we present a full implementation and quantitative evaluation of up to 5x dynamically undersampled data using a four-channel array coil on a 9.4T experimental system. k-t SENSE reconstruction can provide an accurate estimation of LV ejection fraction in rats, using complete short axis cine data of 0.2 x 0.2 x 1mm resolution taking only 2-3 minutes to acquire.
