摘要:
A magnetic resonance elastography method includes application of mechanical oscillations with an oscillation period (T) to an object to be examined to generate mechanical waves in the object. A motion sensitive magnetic resonance acquisition sequence with repetition time TR issued to acquire magnetic resonance signals from the object. This acquisition sequence including application of one or more phase encoding steps within an individual repetition time. The repetition time times the number of phase encodings within one repetition time is not equal to an integer multiple of the oscillation period. Thus a magnetic resonance image of the wave pattern is reconstructed from the magnetic resonance signals assembled in a sample space spanned by the phase of the mechanical oscillation and the phase encoding.
