Sequence diagram for the eZOOM pulse sequence. Slice selective sinc excitation pulse (RF1), spatially selective refocusing pulses (RF2 and RF3), spiral readout (‘Readout’ section), and phase preparation for the next excitation (‘Spoil’ section) including x/y phase rewinders, x/y hysteresis pulses, and z-killer pulse. The large diffusion encoding gradient lobes of this twice-refocused spin-echo DTI sequence are interspersed between the RF pulses and readout.
