Objectives: Endoscopy and imaging are necessary to diagnose glottis carcinoma. Today, CT scan is the gold standard but MR imaging should be more sensitive for neoplastic invasion detection. The purpose of this study was to determine which exam to perform (CT scan or MRI) for neoplastic invasion. Material and methods: This prospective study span a 18 months period. Seven patients with glottis carcinoma (T1-T2) underwent CT and MR imaging before surgery. Findings at imaging and pathologic examination were compared. Results: Both CT and MR imaging were interesting, more specific (90%) than sensitive (74%). The anterior commissure, ventricles, subglottis, thyroid and arytenoid cartilages are the more difficult area analyzing. Conclusion: CT imaging stays the gold standard. MR imaging is more effective on second intention to refine the data. Indications are being improved, with complete cure and more preserved laryngeal functions.
