We have recently reported the construction of a 128-channel receive coil at 3T. The aim of this study was to perform whole heart cine MRI in a single breath-hold with the 128-channel and to compare its performance with that of a 32-element array. Image quality was consistently better with the 128-elements than with the 32-element array, regardless of the acceleration protocol used. Our findings demonstrate whole heart cine imaging with both high spatial and temporal resolution can be robustly performed using TSENSE with 1D acceleration factors of 7 or greater.
