"Echo planar imaging is performed using a pulse sequence in which multiple echoes of different phase steps are acquired using rephasing gradients instead of repeated 180° radiofrequency pulses following the 90°/180° in a spin echo sequence. This is accomplished by rapidly reversing the readout or frequency-encoding gradient. This switching or reversal may also be done in a sinusoidal fashion. Echo planar sequences may use entirely gradient echoes or may combine a spin-echo with the train of gradient echoes."

"In multi-shot echo-planar imaging, the range of phase steps is equally divided into several "shots" or TR periods. For example, an image with 256 phase steps could be divided into 4 shots of 64 steps each."
