Laryngeal imaging.
Knowing the surgical options for treating laryngeal carcinomas and the factors that are used to select patients for radiation therapy leads to a more valuable and relevant interpretation of neck scans in patients with laryngeal tumors. Critical factors include tumor volume; cartilaginous invasion; spread across supraglottic-glottic-subglottic boundaries; infiltration of preepiglottic, paraglottic, and pharyngeal planes; and nodal disease. MR imaging offers greater sensitivity to cartilaginous invasion than CT but shows a higher rate of false-positive studies. Direct coronal MR imaging is often valuable in assessing these issues.
