Abstract：Objective: To compare the value of ultrasonography and MR imaging in diagnosing and T-staging of laryngeal carcinoma. Methods: Ultrasonography and MRI were performed in thirty-six patients with laryngocarcinoma. Histopathologic and surgery findings were performed to validate imaging findings. Results: In 36 patients with laryngeal carcinoma, 34 cases were found by ultrasonography, 32 cases were detected on MRI. The accuracy of ultrasonography and MRI in the diagnosis of T1, T2, T3, T4 staging laryngocarcinoma were 90.9%, 60.0%, 87.5%, 85.7% and 63.6%, 70.0%, 75.0%, 100%, respectively. There were no statistical differences observed in accuracy rating between ultrasonography and MRI(χ2 were 2.329, 0.220, 0.410, 1.077, respectively, all P＞0.10). The overall accuracy rating in T-staging was 80.6% for ultrasonography, and was 75.0% for MRI. There was no significant difference between the two methods in overall T-staging accuracy rating(χ2=0.321, P=0.778). Conclusions: Ultrasonography can provide adequate information with the location, size and infiltration of laryngeal carcinoma, it is a complementary method for laryngoscopy, CT and MR imaging assessment of laryngeal carcinoma.
