Ultra-High Field Neuro MRI is a comprehensive reference and educational resource on the current state of neuroimaging at ultra-high field (UHF), with an emphasis on 7T. Sections cover the MR physics aspects of UHF, including the technical challenges and practical solutions that have enabled the rapid growth of 7T MRI. Individual chapters are dedicated to the different techniques that most strongly benefit from UHF, as well as chapters with a focus on different application areas in anatomical, functional and metabolic imaging. Finally, several chapters highlight the neurological and psychiatric applications for which 7T has shown benefits. The book is aimed at scientists who develop MR technologies and support clinical and neuroscience research, as well as users who want to benefit from UHF neuro MR techniques in their work. It also provides a comprehensive introduction to the field.

Authors
Karin Markenroth Bloch Swedish National 7T facility, Lund University, Sweden. Karin Markenroth Bloch leads the Swedish National 7T facility at Lund University. She obtained a PhD in Nuclear Physics from Chalmers University of Technology, after which she started her career in MRI at DRCMR, Copenhagen, at one of the first Nordic 3T scanners in clinical use. These early experiences stimulated her interest in leveraging the potential of high field strength in clinical applications as much as research and neuroscience. Following a career in Philips as a clinical scientist, Dr. Markenroth Bloch returned to academia to start up and, since 2016, head the Swedish National 7T facility. In this role, her ambition is to make 7T MR broadly accessible to users in a range of applications. Her personal research interests are in methods for velocity-encoded phase-contrast MRI, and their use in studying flow of blood and CSF in the brain.Dr. Markenroth Bloch is engaged in several international and local MRI communities, and in public outreach and popular science initiatives. She has been involved in the ISMRM in a range of capacities, including as a member of the Board of Trustees, the ISMRM High Field Study Group committee and the ISMRM and ESMRMB program committees. Maxime Guye Deputy Director, Centre for Magnetic Resonance in Biology and Medicine (CRMBM), Aix-Marseille University (AMU); Director of the medical site, CRMBM, University Hospital in Marseille, France. Maxime Guye, M.D., Ph.D., is a Neurologist, Professor of Biophysics at the School of Medicine, Aix-Marseille University (AMU), and in the Medical Imaging Department of the Marseille University Hospital. He is also senior consultant in the Department of Clinical Neuroscience. He is deputy director and head of the clinical site of the Centre for Magnetic Resonance in Biology and Medicine (CRMBM), jointly operated by AMU, the French National Centre for Scientific Research (CNRS) and the University Hospital System.
After a fellowship in the UCL Epilepsy Imaging Group (London, UK), he started a research activity on epilepsy imaging using multimodal MRI and electrophysiology in Marseille in 2002. Since 2014 he is leading the 7T MRI facility in Marseille and is particularly involved in clinical research and applications of 7T MRI in neurological diseases. He is actively involved in the MRI community at national and international level. He was elected to the ISMRM High Field Study Group committee and was a member of the ISMRM program committee. He has been elected President of the French Society for Magnetic Resonance in Biology & Medicine and a member of the scientific committee of the French Society of Radiology. Benedikt A. Poser Professor of MR Methods in Neuroscience, Maastricht University, The Netherlands. Benedikt Poser is Professor of MR Methods for Neuroscience at Maastricht University. He has a background in Physics and Business Management, and obtained a PhD in MR Physics at Radboud University Nijmegen in 2009. He gained early experience with Ultra-High Field MRI and its adaption for functional imaging at the Erwin L Hahn Institute in Essen, on one of the first human 7T systems in Europe. Following a fellowship at the University of Hawaii, he returned to Europe in 2013 for a faculty appointment at Maastricht University, where he leads the MR Methods group, and since 2020 holds a Chair within the Cognitive Neuroscience department. The central focus of his work has been the development of acquisition strategies for functional and structural MRI at UHF, and bringing parallel-transmit technologies to neuroscientific application at 7T and 9.4T.
Benedikt Poser is an active member of the MRI community, with engagement in several roles in the European and International societies. Amongst other functions, he served on the ISMRM and ESMRMB program committees, and as President of the ESMRMB. Together with the co-editors of this book he also enjoyed a fruitful and rewarding time on the ISMRM High Field Study Group committee.
