ABSTRACT:
A steady-state free precession fast NMR pulse sequence includes a readout gradient waveform which refocuses the transverse magnetization to produce an S- NMR signal during the subsequent pulse sequence. This readout gradient waveform is shaped to null the gradient first moment and to thereby suppress flow and motion artifacts. In an alternative embodiment, crusher pulses employed in the phase encoding or slice select gradients are also flow compensated.
