Method of Fast Imaging of NMR Parameters with Variably-accelerated Sensitivity Encoding (vSENSE)

Unmet Need: Long scan times due to its requirement that multiple saturation-offset image frames be acquired is the underlying reason that widespread clinical use of chemical exchange saturation transfer (CEST) imaging is hampered. Technology Overview: The invention is a novel method that fully samples one CEST saturation frame, then undersamples the...
