Content:
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
