Emergency Neuroradiology

Encouraged by the success of the Italian editions, the Authors have decided to publish an English version taking into account the latest technical and methodological advances and the consequent new acquisitions in clinical practice. The contribution of Professor R. Jinkins has been essential to carry out both these tasks. The resulting work is an up-to-date technical tool that preserves its original aim of contributing to the training of those radiologists who work in emergency departments. We hope that this revised and extended English version will have the same success as the pre- ous Italian editions, thereby confirming the validity of our initiative. The work of all the friends and colleagues who have contributed to the making of this book is gratefully acknowledged. Tommaso Scarabino Ugo Salvolini CONTENTS I.
