The present volume is the results of 6 years' work by our team, during which time 2300 CT scans of the pituitary region were carried out. This was made possible by the close collaboration between physicians and technicians in our neuroradiological department, as well as by numerous corresponding physi cians. We wish to express our gratitude for their confidence and our sincere thanks to our colleagues at Besan90n, Dijon, Grenoble, Lyon, Montpellier, and Strasbourg. Furthermore, we especially wish to thank the patients who willingly accepted the difficult requirements of these studies. We are grateful to the technicians at the Neuroradiology Department of the Centre Hospitalier et U niversitaire de Besan90n, who have perfected the methodology so as to meet the ever increasing imperatives for precise anatomical mapping of the pituitary gland and the surrounding region; without their efforts, this book would never have been possible. Finally, we wish to express our thanks to the medical photographer of our group, as well as the secretarial staff for their contribution to the successful production of this work. We thank Labora toires Guerbet and General Electric for their excellent assistance, and Springer Verlag for their care and competence in the production of this book. In writing Computed Tomography of the Pituitary Gland, we have sought to develop morphological study of the pituitary gland to a degree of reliability comparable to that of laboratory findings in endocrine disorders.

The cervical spine is always examined initially using standard radiographs, which often provide a sufficient basis for diagno- sis. Malformations, tumours, more frequently trauma, rheuma- tism, and even plain neck pain require a radiological exam- ination. The interpretation of radiological images is often difficult because of overlapping pieces of bone, the summation phe- nomena and the diversity of projections. In this book, two- or three-dimensional CTscans accompany the standard radiographs, serving as an excellent aid for com- prehension. It is almost as if the reader actually had the bones shown in the radiographs in his hands. From then on, everything becomes easy, superimpositions vanish, traps come to light, anatomy triumphs, and the images takes on life. Besanl$on, 1990 J .-F. BONNEVILLE, F.

It will serve as a guide and point of reference in our task of comprehending the interrelationships between the structures of the cervical spine. This radiograph correctly includes the entire area from the base of the skull to the cervicothora- cic junction. The soft tissues are clearly visible anteriorly, as are the extremities of the spinous processes posteriorly. In this case, with the subject looking straight ahead, is a slight, regular, physiological lordosis ofthe cervical column.

Erste Untersuchungen der Halswirbelsaule werden stets mit Hilfe von Rontgenaufnahmen durchgefuhrt, und in den meisten Fallen genugen diese als Grundlage fur die Diagnose. Missbildungen, Tumoren, und noch ofter Traumata, Rheuma und sogar ganz gewohnliche Nackenschmerzen erfordern eine radiologische Untersuchung der Wirbelsaule. Die Auswertung jedoch ist schwierig. Nimmt man einen Halswirbel in die Hand, so stellt man fest, um welch komplexes Gebilde es sich hierbei handelt. Bei radiologischen Aufnahmen wird die Auswertung noch durch die sich uberlappenden Knochenteile, Anhaufungen und die verschiedenen Blickwinkel erschwert. Das Buch von J.-F. Bonneville und F. Cattin stellt eine originelle Interpretationsmethode von Rontgenaufnahmen vor, die die Auswertung wesentlich erleichtert. Dieses Buch zeigt, dass zwei- bzw. dreidimensionale Computertomogramme eine ausgezeichnete Hilfe zum Verstandnis von konventionellen Rontgenbildern sein konnen. Der Leser bekommt gleichsam Zugang zu jedem Einzelteil des Knochens, und von da an wird alles einfach, Uberlappungen verschwinden, die in der Rontgenaufnahme verborgenen Tucken werden sichtbar, die Anatomie triumphiert, das Bild lebt. Die Halswirbelsaule von J.-F. Bonneville und F. Cattin ist unentbehrlich fur jeden Radiologen in seiner taglichen Praxis, aber ebenso auch fur Chirurgen, Rheumatologen und Physiotherapeuten, die sich fur die Halswirbelsaule interessieren.
