A system uses multiple RF coils in MR imaging and an RF (Radio Frequency) signal generator generates RF excitation pulses in anatomical regions of interest and enables subsequent acquisition of associated RF echo data. A magnetic field gradient generator generates anatomical volume select magnetic field gradients for phase encoding and readout RF data acquisition. The RF signal generator and the gradient generator substantially concurrently acquire first and second volumes of first and second different anatomical regions by providing, a first RF pulse having a first asymmetric shape followed by a successive second RF pulse substantially having the first asymmetric shape but reversed in time, to substantially reduce echo time (TE) differences between acquisition of the first and second volumes and a phase encoding magnetic field gradient prepares for acquisition of data representing the first and second volumes.
