A 3D gradient recalled echo sequence has been developed that samples the three shear wave displacement polarization at 3 time points for a total of 9 image samples. A multi-coil recon generates phase difference images and then uses a 3 point discrete Fourier transform to provide the complex displacement fields. The sequence is shown in breast and head applications.
