[Magnetic resonance tomography of the oral cavity, the oropharynx and the mouth floor: comparison with computed tomography].
42 CT and MR examinations of orofacial tumours have been analysed and their value has been compared. In 78% of cases MR was superior to CT in delineating the tumour borders. T1-weighted and gradient echo sequences after intravenous gadolinium injection were particularly useful. Nevertheless, T-staging based on clinical and CT findings was altered in only two cases (5%) by MR. MR should, at present, be used in those cases where small tumours can not be demonstrated by CT, or where metal artifacts obscure the region of interest.
