摘要:
In a method and apparatus for acquisition of a magnetic resonance (MR) image of tissue containing iron oxide particles frequency-selective inversion of the longitudinal magnetization in the tissue is done before acquisition of the MR image, and acquisition of the MR image is done at a zero crossing of the longitudinal magnetization. For water portions of the tissue, multiple inversion pulses that invert the longitudinal magnetization of the aqueous portions are radiated into the tissue. For fat portions of the tissue, multiple inversion pulses are radiated into the tissue that invert longitudinal magnetization of the fat portions. The inversion pulses for the respective tissue portions individually exhibit a fixed time interval from one another.
