Since the establishment of magnetic resonance imaging the clinical diagnostic of the head and neck has improved substantially and, therefore, in many cases this technique is used in the first place of radiological diagnosis. The feasibility of non-invasive MR angiography and 3-dimensional reconstruction has enlarged the indication field of MRI. This book presents the meaning of this imaging technique for the diagnosis of diseases in head and neck. Excellent figures show the technicaland diagnostical possibilities of this method, the advantages and limitations of which are explained as well. A comprehensive diagnostic strategy for each diagnostic region is presented. This book is disigned for the use of especially radiologists, ENT specialists and surgeins.

In January 1995, 300 participants from Asia, USA, and Europe lively discussed the "State of the Art and Future Aspects of CT" in Peking, China. The workshop was designed to cover all essential aspects of modern CT imaging including the historical development, different techniques, contrast agents, organ systems, and indications. The comparative evaluation of CT versus MRI and ultrasound was a central topic. Additionally, a special session was dedicated to "Angiography Tomorrow." This book summarizes the state of the art in both conventional and spiral CT imaging and provides some suggestions as for the future role of the method.

Seit ihrer Einfuhrung hat die Kernspintomographie zu einer erheblichen Verbesserung der klinischen Diagnostik im Kopf-Hals-Bereich gefuhrt, so dass sie in vielen Fallen bereits an erster Stelle der radiologischen Stufendiagnostik steht. Die Moeglichkeiten der nichtinvasiven MR-Angiographie und der dreidimensionalen Rekonstruktion haben ihren Indikationsbereich noch erweitert und Radiologen und Chirurgen enger zusammengefuhrt. In dem vorliegenden Buch wird die Bedeutung dieses bildgebenden Verfahrens fur die Diagnose von Erkrankungen in der Kopf-Hals-Region fachubergreifend dargestellt. Hervorragendes Bildmaterial zeigt die technischen und diagnostischen Moeglichkeiten der Methode. Ihre Vorzuge und Grenzen im Vergleich zu Computertomographie, Sonographie und Angiographie werden aufgezeigt. Abschliessend wird fur jede Untersuchungsregion eine umfassende diagnostische Strategie vorgestellt. Radiologen, Hals-Nasen-Ohren-AErzte und Chirurgen erhalten mit diesem Buch einen grundlichen Einblick in die vielfaltigen Einsatzmoeglichkeiten dieser Untersuchungsmethode.

With its complex anatomy and diversity of landmarks, the head and neck region poses a special challenge to clinical and radiologic diagnosis. Sound therapeutic decision making requires the use of modern imaging procedures to define the precise location and extent of pathologic processes and delineate the involvement of adjacent structures. Other important information is derived from the vascularity of a lesion, its internal structure, its homogeneity, and the nature of its margins. All these criteria will suggest a radiologic differential diagnosis that forms the basis for an accurate interpretation of the findings. This book offers a systematic approach to differential diagnosis based on the experience gained in more than 4000 comparative clinical and radiologic examinations. Each chapter includes images that illustrate the differentiating criteria that are applied to various types of pathology. Besides demonstrating the key elements of an accurate differential diagnosis, the images show how radiologic tissue characterization is not possible for all lesions, and how imaging can direct the biopsy procedures which may be needed to establish a diagnosis.
