摘要：
A fast magnetic resonance imaging method and system, the method comprising: applying a periodic radio-frequency pulse train to drive the magnetization vector of an imaging volume into a steady state (102)； acquiring a free induction decay (FID) signal and an echo signal alternately in a steady-state free precession sequence (104)； conducting an FID signal imaging and a T2-weighted imaging (106). Alternate acquisition of the FID signal and the echo signal in the steady-state free precession sequence effectively increases the signal-to-noise ratio (SNR) of the acquired signals and reduces the sensitivity of the sequence to motions.
