Chemical Exchange Saturation Transfer (CEST) imaging is an emerging molecular MRI method. It has been difficult for CEST imaging to adopt into clinical routine since CEST imaging is required relatively long scan time due to multiple saturation offsets. Here, we propose a novel, highly accelerated 3D CEST reconstruction technique by combining parallel imaging and compressed sensing.
