Evaluation of Laryngeal Tumors by Multi-Detector Computed Tomography and Magnetic Resonance Imaging
Background: Twenty to forty percent of all head and neck malignant tumors are laryngeal tumors, while sixty to seventy percent of laryngeal cancers are found at advanced stages. Laryngeal cancer is diagnosed using several techniques, such as magnetic resonance imaging (MRI) and contrast-enhanced Computed Tomography (CT). Objective: The aim of this study was to evaluate the role of multislice computed tomography (MSCT) and magnetic resonance imaging (MRI) in diagnosis of laryngeal tumors. Patients and methods: Twenty-four patients, 21 men and 3 women. Their ages ranged from 25 to 75 years who were referred form ENT department, Zagazig University Hospital. All patients underwent clinical examination, indirect laryngoscopic examination, CT, MRI and histopathological study. Results: A highly significant difference was found between MRI and CT in masses and LNs finding among the studied patients by both MRI and CT. Both investigations agreed that 16.7 % of the studied patients had glottic mass, 12.5 % had glottic and infra glottic, and 41.7% had supra glottic and glottic with infiltration, degree of agreement in diagnosis of masses and LNs between both MRI and CT is very good (kappa= 0.775, p-value=0.000*). Agreement between CT and MRI regarding masses and LNs among the studied cases; glottic mass alone by CT 33.3% but by MRI 16.7% and glottic mass plus other sites and lymph nodes by CT 66.7% but by MRI 83.3%. Conclusion: When it comes to T staging of laryngeal carcinomas, MRI shows greater accuracy than CT. Laryngeal carcinomas with AVC involvement may be better assessed for thyroid cartilage involvement and T stage if CT and MRI are used together.
