Abstract:
In a magnetic resonance method and device to generate spatially resolved, quasi-T2-weighted magnetic resonance signals from an examination region, an initial magnetization is flipped in a first direction with a first gradient-balanced SSFP sequence. Spatially coded first magnetic resonance signals from the first gradient-balanced SSFP sequence are detected during the transient portion of the first SSFP sequence. An initial magnetization is flipped in a direction opposite the first direction with a second gradient-balanced SSFP sequence. Spatially coded second magnetic resonance signals from the second gradient-balanced SSFP sequence during the transient portion of the second gradient-balanced SSFP sequence. The first and second magnetic resonance signals are constructively superimposed into overlay signals. Image data with a predominant T2 weighting are reconstructed from the overlay signals, or are used for spatially resolved estimation of the T2 relaxation time constant.
