Radiological examination of the nasal cavity

The complex anatomy of the interior of the nose presents a challenge in radiological imaging. Several radiologic modalities applied in the assessment of anomalies and pathologic changes in the nasal cavity are presented, illustrated by reference to various cases. The excellent ability of computed tomography to reveal valuable information concerning both benign and malignant lesions is emphasized. Magnetic resonance imaging has further extended the possibilities in diagnosis because of its high soft-tissue contrast resolution and multiplanar imaging capabilities.
