Magnetic resonance imaging (MRI) is now considered the imaging modality of choice for the majority of disorders affecting the central nervous system. This is particularly true for gray and white matter disorders, thanks to the superb soft tis sue contrast in MRI which allows gray matter, unmyelinated, and myelinated white matter to be distinguished and their respective disorders identified. The pre sent book is devoted to the disorders of myelin and myelination. A growing amount of detailed in vivo information about myelin, myelination, and myelin dis orders has been derived both from MRI and from MR spectroscopy (MRS). This prompted us to review the clinical, laboratory, biochemical, and pathological data on this subject in order to integrate all available information and to provide im proved insights into normal and disordered myelin and myelination. We will show how the synthesis of all available information contributes to the interpretation of MR images. After a brief historical review about the increasing knowledge on myelin and my elin disorders, we propose a new classification of myelin disorders based on the subcellular localization of the enzymatic defects as far as the inborn errors of me tabolism are concerned. This classification serves as a guide throughout the book. All items of the classification will be discussed and, whenever relevant and possi ble, be illustrated by MR images.

The first edition of this book was well received by readers and reviewers and we are very grateful for the positive reactions. We were convinced then, and even more now, that MRI and MRS have much to offer in diagnosis, therapy monitoring and research of hereditary and acquired myelin disorders. In the last few years, a great deal of new information has come available, concern ing the genetic basis of inborn errors of metabolism and neurodegenerative disor ders, the role of subcellular structures, the enzyme biochemistry, the pathophysio logical mechanisms of posthypoxic-ischemic cerebral damage, and the inflammato ry processes in infectious and inflammatory disorders. MR images of many rare disorders have become available, either in our own experience or published by other groups. MR spectroscopy could confirm its role in certain clinical applica tions. Because of these developments, it was necessary for us to rewrite the book almost completely. In some fields developments are so fast that we may not have caught all the latest developments. The pattern of the new approaches has, however, been established, making the assimilation of newly available information easy. We are extremely grateful for the help of colleagues to make this book as com plete as possible. The positive reactions of those from whom we requested MR pictures or other forms of support were of enormous encouragement to us during our efforts to complete this project. We hope this work will be as warmly welcomed by our colleagues as the first edition.
