Chemical Exchange Saturation Transfer Imaging

Michael T. McMahon, Ph.D, is an Associate Professor of Radiology at the Johns Hopkins University School of Medicine and a Research Scientist in the F.M. Kirby Research Center for Functional Brain Imaging at the Kennedy Krieger Institute. Dr. McMahon earned his Ph.D. in physical chemistry from the University of Illinois at Urbana-Champaign in 1999 and was awarded a fellowship to continue his training at the Massachusetts Institute of Technology before taking a Research Associate position with Peter van Zijl in 2003. His research at Johns Hopkins University and Kennedy Krieger Institute is focused on the development of diaCEST contrast agents for medical applications and imaging schemes to maximize their potential. Dr. McMahon has been elected to the position of Program Director for the Cellular and Molecular Imaging Study Group at the International Society for Magnetic Resonance in Medicine (ISMRM) and together with Drs. Gilad, Bulte and van Zijl organized the third CEST imaging workshop (OctoberCEST) in Annapolis, MD.Dr. Jeff W.M. Bulte, Ph.D, is a Professor of Radiology in the Division of MR Research, with joint appointments in Oncology, Biomedical Engineering, and Chemical & Biomolecular Engineering. He serves as the Director of the Cellular Imaging Section in the Institute for Cell Engineering at the Johns Hopkins University School of Medicine. In 1991, Dr. Bulte obtained his Ph.D. summa cum laude from the University of Groningen, The Netherlands. He then spent 10 years in the Laboratory of Diagnostic Radiology Research at the National Institutes of Health before moving to Johns Hopkins University in 2001. He has won several awards, including an ISMRM Gold Medal and the Torsten Almén Award for Pioneering Research in Contrast Media.Assaf A. Gilad, Ph.D, is an Associate Professor of Radiology at the Johns Hopkins University School of Medicine and the Institute for Cell Engineering. After obtaining his Ph.D. from the Weizmann Institute of Science, Rehovot, Israel in 2003, he received his postdoctoral training under the supervision of Drs. Jeff Bulte and Peter van Zijl at Johns Hopkins University. In 2007 he joined the Radiology department as junior faculty and has continued to develop new genetically encoded technologies for cellular and sub-cellular molecular CEST imaging. Peter C.M. van Zijl, Ph.D., is a Professor of Radiology in the Division of MR Research of the Department of Radiology at Johns Hopkins University School of Medicine, and the founding Director of the F.M. Kirby Research Center for Functional Brain Imaging at Kennedy Krieger Research Insitute. Dr. van Zijl received his Ph.D. in mathematics and physics (Physical Chemistry) from the Free University, Amsterdam in 1985. He did fellowships in Chemistry, Carnegie Mellon University (1985-87) and in vivo spectroscopy (National Cancer Institute, NIH from 1987–1990) and was Assistant Professor at Georgetown University from 1990–1992. He moved to Johns Hopkins University in 1992. Dr. van Zijl is a Fellow of both the ISMRM and the ISMAR. He received the Gold medal of the ISMRM in 2007 for contributions in MR spectroscopy, diffusion imaging, and functional MRI. He is a distinguished Investigator of the Academy of Radiology Research (2012) and in 2016, together with Robert Balaban, received the Laukien Prize for his contributions to developing the CEST field.

"This textbook is very helpful for those who are eager to fully understand the principles and development of chemical exchange saturation transfer (CEST) techniques. One strength of this book is in the discussion of probes, and another strength is having Sture Forsén and Robert Balaban describe their early studies. This book will have a great impact promoting the clinical translation of CEST imaging."—Prof. Renhua Wu, Shantou University, China"This book presents an in-depth and comprehensive description of CEST physics, techniques, and applications. It is in time for the dawn of label-free molecular imaging that explores chemical exchange phenomena the nature offers. It is also a collection of very updated perspectives of the future of CEST magnetic resonance imaging (MRI), quite informative, and fun to read for imaging physicists, radiologists, and clinician scientists." —Prof. Ed X. Wu, The University of Hong Kong, Hong Kong"This is an excellent book on CEST MRI with state-of-the-art chapters from thought leaders in the field. It touches on all aspects of CEST: image acquisition methods and data processing, development of exogenous CEST probes, and applications of CEST in clinical and biomedical imaging. A very valuable addition to biomedical imaging canon, and a text that will be beneficial to students and experts alike." —Prof. Peter Caravan, Harvard Medical School, USA"This book has been edited by faculty from one of the leading centers with extensive experience of chemical exchange saturation transfer (CEST) MRI and is the first to focus exclusively on this specific imaging technique. The authors include many of the leaders in the field, and it belongs on the shelf of anyone seriously involved in CEST work. It has broad breadth of coverage which makes it a go-to reference for overviews of many sub-specialty applications. It is clearly valuable as a standard in the field and I expect it will serve as the essential starting point for in-coming graduate students beginning CEST research and for established researchers delving into a new area." —Dr. Daniel F. Gochberg, Vanderbilt University Institute of Imaging Science, USA"This timely book describes the history of the technique’s development and the underlying theory and then goes on to review its latest applications. It is a comprehensive and insightful book written by the leaders in the field. It is a must read book for anyone already in the CEST field, or thinking of entering the field and, given the growing popularity of the methods described here, should be read by anybody working in the field of in vivo MR."—Prof. Kevin Brindle, University of Cambridge, UK, Molecular Imaging and Biology, 2017
