[The diagnosis of malignant neoplasms of the naso- and oropharynx by using computed magnetic resonance tomography in an ultralow field].

MR tomography examination of 51 patients with maxillofacial or cervical cancer provided adequate diagnostic information especially in the absence of bone involvement. The method proved efficient in differentiating tumors with inflammation, in tumor localization, evaluation of its size and spread, outline, structure, invasion. It is safe, noninvasive. For differential purposes the technique is most beneficial in impulse double echo mode with proton density and T2.
