Method and apparatus for imaging magnetic resonance with inversion reserve to attenuate liquid signals

摘要

An MR imaging method using NMR phenomenon and including the following steps: emitting a first group of RF pulses including a first inversion RF pulse, and excitation RF pulses emitted to excite a plurality of slices in a predetermined order; emitting slice-selecting gradient field pulses; emitting phase-encoding gradient field pulses; collecting a first group of echo signals; emitting a second group of RF pulses including a second inversion RF pulse having substantially the same frequency band as the first inversion RF pulse, and second excitation RF pulses emitted to excite the plurality of slices in a reverse order; emitting slice-selecting gradient field pulses; emitting phase-encoding gradient field pulses; collecting a second group of echo signals; repeating this pulse sequence while varying the phase-encoding gradient field pulses; adding two data corresponding to each slice, which data are included, respectively, in a first group of data and in a second group of data, thereby forming a new group of data; and reconstructing slice images.
