Claim 16:
17. A magnetic resonance imaging (MRI) system, comprising:
a control sequencer coupled to a gradient subsystem comprising gradient amplifiers and gradient coils and an MRI subsystem comprising a static z-axis magnet and one or more radio frequency (RF) coils; and
a data acquisition and display (DADC) device comprising memory comprising programmed instructions stored thereon and one or more processors configured to execute the stored programmed instructions to:
generate first and second gradient waveforms each comprising a plurality of segments collectively comprising a spiral ring retraced in-out trajectory;
instruct the control sequencer to communicate with the:
MRI subsystem to produce a turbo spiral echo (TSE) pulse sequence to generate a corresponding series of nuclear magnetic resonance (NMR) spin echo signals, wherein the TSE pulse sequence comprises a series of RF refocusing pulses; and
gradient subsystem to generate during an interval adjacent to each of the series of RF refocusing pulses a pair of gradient pulses each according to one of the first or second gradient waveforms; and

construct an image from digitized samples of the NMR spin echo signals.
