Single-Scan Spatially Encoded MRI - Principles & Applications

In recent studies we have introduced an alternative scheme for ultrafast imaging based on imparting a spatial rather than a conventional temporal encoding of the spins interactions. We continue to explore this approach using an integrated spatio-temporal encoded technique producing 2D single-shot images under non-ideal conditions. This hybrid imaging scheme is shown to be superior to traditional protocols such as Spin-Echo EPI, in non-homogeneous magnetic field environments. Further enhancements of the basic technique are presented, capable of producing T2* self-refocused images as well as significant decreases in the image acquisition time by employing a novel encoding and post-processing scheme.
