ABSTRACT
Computed tomography (CT) is the main imaging modality used to assess paranasal sinus disease as this provides the highest resolution and, with the use of bone algorithm, the best definition of bony structures [1]. The role of magnetic resonance imaging (MRI) in paranasal sinus disease consists primarily of assessing intracranial and orbital complications of sinus inflammatory disease, helping to differentiate aggressive infectious or inflammatory disease from neoplasm, and assessing the extent of neoplasm [1,2].
