Answer

Computed tomography scanning is the preferred imaging method for rhinosinusitis. A complete sinus CT scan with frontal and coronal planes is used if an alternative diagnosis (eg, tumors) must be excluded. CT scanning is characteristic in allergic fungal sinusitis and is one of the major criteria for diagnosis.
