General review of magnetic resonance elastography

Figure 4 Gradient-echo magnetic resonance imaging sequence with motion sensitizing gradient applied along the slice selection direction (G_Z) to detect cyclic motion in that direction. A phase offset (θ) between the MSG and the acoustic driver was adjusted to acquire wave images at different time intervals during a single period of wave motion.
