Stem cell-based regenerative therapy has become a frontier in modern medicine. For the success of both basic research and clinical application of stem cell technology, it is essential to have noninvasive methods to monitor the delivery of transplanted stem cells, track migration/homing of stem cells to the targets, and assess survival and function of the transplanted stem cells at the targets. Magnetic resonance imaging (MRI) represents a promising technology fitting in this necessity. So far, scientists from various disciplines around the world have done outstanding works in developing different MR techniques for in vivo imaging of stem cells, so-called cellular MRI. The aim of this book is to facilitate such translation of advanced cellular MRI techniques from laboratory benches to pre-clinical animal studies, and, ultimately, to clinical practice. The authors are from several continents around the world, with their expertise in the fields of stem cell science, biomedical engineering, medicine, pathology, medical imaging, and interventional radiology. We hope this book will provoke common interests, brainstorming and cooperation among professionals in both stem cell science and medical imaging, and bring regenerative medicine one step closer to benefiting the patients.

This is the first textbook dedicated to CEST imaging and covers the fundamental principles of saturation transfer, key features of CEST agents that enable the production of imaging contrast, and practical aspects of preparing image-acquisition and post-processing schemes suited for in vivo applications. CEST is a powerful MRI contrast mechanism with unique features, and the rapid expansion it has seen over the past 15 years since its original discovery in 2000 has created a need for a graduate-level handbook describing all aspects of pre-clinical, translational, and clinical CEST imaging. The book provides an illustrated historical perspective by leaders at the five key sites who developed CEST imaging, from the initial saturation transfer NMR experiments performed in the 1960s in Stockholm, Sweden, described by Sture Forsen, to the work on integrating the basic principles of CEST into imaging by Robert Balaban, Dean Sherry, Silvio Aime, and Peter van Zijl in the United States and Italy. The editors, Drs. Michael T. McMahon, Assaf A. Gilad, Jeff W. M. Bulte, and Peter C. M. van Zijl, have been pioneers developing this field at the Johns Hopkins University School of Medicine and the Kennedy Krieger Institute including contributions to Nature Medicine, Nature Biotechnology, Nature Materials, and the Proceedings of the National Academy of Sciences. As recognition for their initial development of the field, Drs. van Zijl and Balaban were awarded the Laukien Prize in April 2016, established in 1999 to honor the memory of Professor Gunther Laukien, a co-founder of Bruker Biospin GmbH.
