title: Imaging of sinonasal tumors.
abstract: Imaging of the paranasal sinuses and the nasal cavity provides important anatomic information in the evaluation of suspected neoplasia. The primary modalities employed are conventional films, computed tomography (CT) and magnetic resonance imaging (MRI). Although plain sinus films remain the screening procedure of choice, CT is the preferred modality for more detailed assessment of the paranasal sinuses and the nasal cavity. When soft tissue discrimination is required, MRI is indicated. Imaging studies are used to define the limits of disease, not to diagnose malignancy.
