Highly Accelerated MR Elastography

John C. Bosshard¹, Steven M. Wright¹

Highly parallel imaging with a 64 channel receive array in a "sandwich" configuration was used to capture MR elastography images of an emerging mechanical wave at 156 x 125 &[mu]m resolution. The same system was also used to perform simultaneous single echo acquisition imaging at the top and bottom boundaries of the sample using a non-linear gradient coil for compensation of RF coil phase. This method may have applications in microscopic MRE or for monitoring of elastic properties during single-shot events.
