Applications of Echo Planar Imaging with Keyhole (EPIK) to Layer-Specific fMRI and Oxygen Extraction Fraction

Abstract

The background to echo planar imaging with keyhole (EPIK) forms the basis of an imaging methodology for exploring brain function. Compared with EPI, EPIK affords a superior apparent temporal resolution as well as improved spatial resolution and somewhat better immunity from susceptibility related artefacts. Results from 3T will be used to demonstrate the above advantages.

Application of EPIK at 7T has been shown to enable near whole-brain coverage with a voxel size of 0.6 x 0.0 x 0.6mm in a modest TR of 3.5s. Applications to layer-specific (depth-dependent) fMRI will be shown.

The application of EPIK at 3T, in the guise of a 10-echo sequence, has been used to rapidly map T2, T2* and T2’ enabling the calculation of an oxygen extraction map.  This rapid variant of EPIK enables the acquisition of 20 slices, 10 echoes per slice – from which the OEF maps are calculated – in only 57s. Initial results from a proof-of-concept study will be presented.

Speaker Biography

Having been awarded his PhD from the University of Manchester in 1989, Prof. Dr Jon Shah has made major contributions to the field of medical imaging through the development and optimisation of innovative imaging devices and techniques for use in clinical and fundamental brain research. He has published approx. 600 refereed publications and 55 patents.

Prof. Shah is Director of the Institute of Neuroscience and Medicine-4 and is a co-director of the Jülich-Aachen Research Alliance (JARA-BRAIN) at the Forschungszentrum Jülich, Germany, with professorial appointments in the Faculty of Medicine and the Faculty of Natural Sciences at the RWTH Aachen University.

This seminar is free to attend and is open to all, both within and outside the University. Feel free to come along to the location above if you wish to attend in person, if you wish to attend on Zoom, please register your interest to attend online using the link above.
