3D hybrid radial acquisitions using steady state free precession (SSFP) contrast have already achieved strong results in coronary, cardiac function, and peripheral vasculature imaging. We present methods to sample k-space faster by utilizing the normally unused frequency dephaser, rephaser pulses, and gradient ramps besides the conventional readout. This technique is first applied in a single breath-hold multiple phase cardiac study.
