[MRI/CT x-ray comparison in the pre-operative evaluation of cancer of the larynx. Apropos of 46 cases].
The authors present the comparative value of CT scan and MRI in the pre-operative staging of 46 laryngeal carcinomas. The "in depth" evaluation conducts the choice of conservative surgery. CT scan is the reference but MRI reveals itself as effective and even more in certain cases. The spontaneous contrast gradient for soft tissues of the MR imaging explains this effectiveness of the method. The paraglottic space and the subglottic extension are more easily studied by MRI. If the expansion of the MRI Unities allows this indication of the pre-operative staging of laryngeal carcinomas is an excellent one.
