Cover-Design and Typesetting: Verlagsservice Teichmann, 69256 Mauer 21/3150 - 5 4 3 2 1 0 - Printed on acid-free paper Foreword This volume provides a multimodality imaging approach to the pathology of the foot and the ankle, covering both the various imaging techniques and all clinical aspects of diseases of these anatomic areas. The chapters on technique are compact but still deal comprehensively with all spe cific facets of the problem. The clinical chapters are well written, detailed and superbly illustrated. The editors succeeded in assembling an excellent group of international experts from the European continent as well as from the USA to cover all commonly held modern views and concepts on the topic. This outstanding volume will serve the needs not only of general radiologists dealing in their daily practice with the frequently occurring traumatic conditions of the ankle and foot but also of specialised musculoskeletal radiologists looking for guidance in their management of patients suffering from arthritis, osteochondritis, infectious or metabolic diseases or even the rare tumoral and tumour-like conditions of this part of the lower limb. It can be recommended highly as invaluable reading not only to radiolo gists but also to orthopaedic surgeons and rheumatologists. I am confident that this excellent book will meet the same success as the volume on the knee already published in this series by Dr. Mark Davies. Leuven ALBERT 1. BAERT Preface As our understanding of the disease processes and biomechanics of foot and ankle disorders improves there is a need to continuously update the radiologists, orthopaedic surgeons and other professions working in this field. Several recent texts on the foot and ankle have concentrated on a single imaging technique such as MR imaging. This book, in common with several others published in this series, takes a dual approach to the sub ject. The first section acquaints the reader with the full range of techniques available for imaging the ankle and foot pathology, emphasising indications and contraindications. The seven chapters include contributions on radiography, computed tomography, MR imaging and ultrasound. The remaining fifteen chapters discuss the optimal application of these techniques to specific pathologies, highlighting practical solutions to everyday clinical problems. The editors are grateful to the international panel of authors for their contributions to this book, which aims to provide a comprehensive overview of current imaging of the foot and ankle.
