Rapid 3D-FFE MR Image Acquisition using Aliased k-space Acquisitions

ewly developed MRI scan acceleration method RATE showed promises to speed-up MRI scans while preserving acquisition SNR through simultaneous acquisitions of distinct k-space phase encodes. We present our ongoing work of implementation of aliased k-space acceleration techniques in 3D MRI acquisitions with the goal of accelerating 3D dynamic MRI acquisitions. Our preliminary implementation of RATE to accelerate 3D-FFE sequence was able to produce two fold of reduction in scan time. Our ongoing work will involve developing strategy to achieve even higher acceleration factors for 3D T1 acquisitions including testing the performance of the sequence on healthy subjects.
