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.
磁共振成像（MRI）在研究解剖结构复杂的颈面部区域肿瘤扩展方面具有显著优势。多平面成像方法能够更好地分析肿瘤的解剖关系，包括与血管结构的关系，而无需注射造影剂。该方法能够准确区分组织，对检测肿瘤组织非常敏感。CT显示不佳、对比度增强不良或位于肌肉环境中的病变，在MRI上能得到很好的显示。要让患者在长时间检查中完全保持不动仍存在一些困难。我们认为MRI对颈面部肿瘤的诊断检查有很大帮助，可能成为该领域的首选成像技术，特别是如果通过快速成像方法进一步缩短检查时间，以及改善MRI设备的可及性。
