Imaging the brain at ultra-high resolution using 3D FatNavs

Currently the maximum resolution we can reach with MRI is not restricted by the hardware - theoretically longer scans can always allow higher resolution - but instead the limitation is imposed by how long the subject is able remain sufficiently still within the scanner. In this talk I will introduce our recent work using repeated rapid acquisitions at the fat frequency (FatNavs) in order to track the microscopic movements of the head which are inevitable during extended scans, even with healthy volunteers accustomed to the scan environment. I will briefly describe how this allows us to correct for the motion-induced image artifacts, and also present our latest results imaging the brain at exceptionally high spatial resolution.
