[Magnetic resonance imaging (MRI) of cervico-facial tumors]

Magnetic Resonance Imaging (MRI) gives substantial advantages for the study of tumoral extension in the anatomically complex cervico-facial region. The multiplanar approach permits a better analysis of the anatomical relationships of the tumor, including relationships with the vascular structures, without the need for injecting a contrast medium. The method is able to accurately differentiate tissues and is very sensitive for detecting tumoral tissue. Lesions poorly visible with CT, with poor contrast enhancement or lying in a muscular environment, are well demonstrated. Some difficulties remain for obtaining from patient a complete immobility for a long examination. We think MRI gives a substantial benefit for the diagnostic work-up of cervico-facial tumours, and could be the first imaging technique in this area, particularly if further shortening of the examination time is gained with fast imaging methods and if availability of MRI installations is improved.
