Title: Advanced Parallel Imaging for brain MRI acquisitions

Abstract: The “controlled aliasing” method, or CAIPI has been proposed as a way to improve the performance of parallel imaging in MRI; enabling a much more efficient MRI acquisition. This work presents some of the latest advancement in CAIPI, with blipped-CAIPI and Wave-CAIPI technologies. The use of such techniques along with modern large channel count receiver arrays of 32-ch or 64-ch, has enabled an unprecedented order of magnitude acceleration in brain MRI acquisitions. Such rapid imaging is highly beneficial to a number of neuroscientific and clinical applications of MRI. This talk will focus on two application areas: (i) diffusion and fMRI acquisitions for Connectomics, where our Simultaneous MultiSlice (SMS) imaging with blipped-CAIPI has provided dramatic increases in temporal and spatial resolution: with 1.5-mm whole-brain acquisition achievable now in just over a second and 2.5-mm whole-brain acquisition in 350ms (ii) Rapid anatomical brain imaging, where the Wave-CAIPI technology has enabled rapid, sub-millimeter isotropic resolution brain imaging. In particular, Wave-CAIPI can provide up to 15 fold acceleration in the highly used clinical sequences such as T2w/FLAIR RARE (TSE/FSE).
