MR imaging of laryngeal cancer
1987
Forty-four consecutive patients with laryngeal carcinomas presenting at different stages of the disease were investigated by magnetic resonance (MR) imaging. Twelve patients (six with primary lesions and six with recurrent tumors) underwent laryngectomy, and the macro- and microscopic appearance of the sliced specimens were correlated with MR imaging. In the remaining patients surgery was not performed, and MR results were compared with the laryngoscopic findings. Cancerous tissue was seen on T1 weighted images as a homogeneous mass of intermediate signal intensity, slightly higher than infrahyoid muscles. The MR examinations failed mainly in patients with tumor recurrence who had undergone previous radiation treatment.
