1. An MRI apparatus to acquire images comprising: a MRI system having a plurality of gradient coils positioned about a bore of a magnet to impress a polarizing magnetic field and an RF transceiver system and an RF switch controlled by a pulse module to transmit RF signals to an RF coil assembly to acquire MR images; and a computer programmed to: acquire RF coil sensitivity data for a region-of-interest (ROI); acquire un-gated MR data from the ROI; reconstruct a series of real-time MR images from the acquired un-gated MR data; identify at least one slice from at least one image of the series of real-time MR images to obtain a slice identified for localization within the ROI; acquire triggered MR data from the at least one slice to partially fill k-space for the slice identified for localization; determine MR data for unacquired k-space from the RF coil sensitivity data and the triggered MR data to continue to fill k-space; perform a CINE interpolation of the triggered MR data; and reconstruct high-resolution images of the slice identified for localization.
