Magnetic Resonance Imaging of Children Mervyn D. Cohen, MB, ChB and Mary K. Edwards, MD. Philadelphia: B.C. Decker, 1990, $169.50, 973 pages. Magnetic Resonance Imaging of Children, published four years after Dr. Cohen’s first book on this subject, Pediatric Magnetic Resonance Imaging (Saunders], has been eagerly awaited as we have witnessed tremendous advances in magnetic resonance (MR) imaging in all age groups. The first book was authored by Dr. Cohen alone and was 162 pages long. The new, much longer book, co-authored with Dr. Mary K. Edwards, expands the scope to include pediatric neuroradiology and has 30 contributors. The chapters devoted to musculoskeletal imaging alone are longer than Dr. Cohen’s entire first volume. Fortunately the book is so structured that there is remarkable uniformity of style from chapter to chapter. The book is practical, logical, comprehensive, clearly written, and accessible. It is divided into three sections. Section I, the shortest section, deals with basic physics, artifacts, safety, and biological effects. A chapter is devoted to sedation, anesthesia, and patient monitoring. Section II deals with head and spine imaging and Section III with body imaging. Each chapter starts with a brief outline that makes the book easy to use. The illustrations are numerous, of excellent quality, and well labelled. The role of MR imaging in relation to the other imaging modalities is addressed for many different conditions. In some instances the illustrations of the other modalities and explanatory diagrams appear side-by-side with the MR image. Technical aspects of MR imaging are comfortably integrated into each chapter. Several chapters provide useful tables summarizing clinical problems. Each chapter contains a comprehensive list of up-to-date references. In Section II the chapters on the brain include normal anatomy and development, congenital malformations, trauma and mechanical disorders, tumors, inflammation and infection, vascular disorders, and metabolic, endocrine, and iatrogenic lesions. Extracranial disease is covered in the chapters on the orbit and the ears, nose, throat, and skull base. The chapters on the spine include dysraphism, tumors, and miscellaneous disorders.

lus is covered quite briefly, and MR angiography is mentioned in the text, but no figures are given. In Section III there are individual chapters on the cardiovascular system, respiratory system, gastrointestinal system, genitourinary system, reticuloendothelial and endocrine systems, and primary disorders of the bone marrow and tumors of the musculoskeletal system. The final chapter includes information on infectious, traumatic, mechanical, collagen, and miscellaneous disorders of the musculoskeletal system. This impressive volume will be a highly useful addition to the libraries of pediatric radiologists, neuroradiologists, musculoskeletal radiologists, and any radiologists who are even occasionally involved with pediatric imaging. It will be a valuable reference for radiology residents as well as for pediatricians, pediatric neurologists, neurosurgeons, and orthopedic surgeons. PAULA

this vol-

ume provides separate introductions to magnetic resonance imaging (MRI) and magnetic resonance spectroscopy (MRS). After a short chapter explaining the structure of the book and another chapter on general NMR theory, there are three chapters on imaging (including a long chapter on clinical applications) followed by three chapters on spectroscopy. The final two chapters are devoted to siting, safety, and patient preparation. Much of the explanatory power of the presentation is provided by numerous well thought out and wellproduced figures. On the other hand, the quality of the clinical images varies considerably. Obviously, much thought has been given to the layout of this book. There is an extensive index. In addition, there is a glossary (although it fails to include several terms such as field lock and spoiler




pulses, which remain undefined throughout the text). There is even an introductory table of abbreviations and symbols with page references (although it fails to include the rather confusing M on page 41). These minor failings are closely related to a stylistic feature of the book which maintains the interest of more experienced readers but may seriously frustrate newcomers. For example, on page 16 in the introductory chapter shortly after first presenting Larmor’s equation, the reader is exposed to the pulse width and power requirements for transmitted rf pulses. This material is really an aside and should be designated as such. The repeated inclusion of such advanced material without adequate preparation can easily derail students who have yet to comprehend the relative significance of various aspects of the theory. A more serious deficit is found in the treatment of flow. The presentation contained in this volume does not provide sufficient background to allow the reader to follow current developments in vascular and diffusion/perfusion imaging. Similarly the treatment of safety aspects is much too cursory and does not include sufficient references to the rather extensive literature now available. On the other hand, extended coverage is provided for topics such as saturation transfer and spectral localization that receive scant attention in conventional textbooks. In summary, the authors comprise a very experienced team, and their novel approach provides many interesting insights even though it is not comprehensive. Supplemented by lectures, this book would be a reasonable text for technologists and physicians as well as good auxiliary reading for anyone interested in MRI or MRS. R. JAMES R. KNOWLES,

Advances in Radiation Protection Volume 1 edited by Martin Oberhofer. The Netherlands: Kluwer Academic 1991, $127.00, 376 pages.

Dordrecht, Publishers,

The radiation programs organized within the framework of the CEC under the aegis of the Euratom Treaty are discussed throughout the book. In the member states of the CEC, approximately 30% of the electrical energy is produced by nuclear techniques. There are a number of references throughout the book to the Chernobyl accident, and it is clear that this accident has provided an incentive to expand and solidify CEC activities. CEC research programs in medicine and dosimetry are covered in various chapters. Nonionizing radiation and magnetic resonance imaging are each the subject of a chapter. It will be interesting for medical physics professional to compare the organization of the CEC programs with national programs in the US and Canada. With the notable exception of Dr. B. Lindell, many of the authors may be relatively unknown to US audiences. Considerable space is devoted to implementation of the recommendations of the International Commission on Radiation Protection (ICRP Reports 26, 30 and 37) and the International Commission on Radiation Units (ICRU Reports 33 and 39). These recommendations are partially reflected in the recent revisions to lOCFR20; however, implementation remains a topic of some controversy in the US. The CEC programs have adopted these recommendations with minimal reservations. Physicists will find the chapters on the status of beta, neutron, and high-dose dosimetry to be good general reviews of these topics. Six chapters deal with medical health physics topics. These chapters present a review of quality assurance criteria, image quality scoring, dose assessment criteria, and risk evaluation. Although there is little new research material presented, these chapters present well the overall topics seen from the perspective of the CEC programs. This book will be of limited interest to radiologists, and of most interest to medical physicists. Again, medical physicists will find it interesting to compare CEC programs in imaging with other national efforts. This book represents an interesting first volume in the proposed series, and is a promise of things to come. JEAN ST. GERMAIN,

This book is the first volume in health physics and radiation protection published by the Euro Course series for the Commission of the European Communities (CEC). The papers presented in the book are taken from an “Advanced Seminar on Selected Topics in Radiation Protection” held in October 1989, in Lisbon, Portugal. The book is not typeset, but represents well the genre of camera-ready copy-texts now available.
