A method, system, and apparatus including a magnetic resonance imaging (MRI) apparatus that includes an MRI system having a plurality of gradient coils, a radio-frequency (RF) transceiver system, an RF switch controlled by a pulse module to transmit RF signals to an RF coil assembly, and a computer. The computer is programmed to implement a spin echo sequence to acquire magnetic resonance (MR) data, where the spin echo sequence includes an excitation RF pulse and at least one refocusing pulse per repetition time (TR) of the excitation pulse. The computer is also programmed to transmit at least two component RF pulses in parallel channels during implementation of the spin echo sequence to produce a first refocusing RF pulse and programmed to reconstruct an image from spin echo sequence image data.
