Answer

CT scanning has poor specificity for the diagnosis of acute sinusitis, demonstrating sinus air-fluid levels in 87% of individuals with simple upper respiratory tract infections and 40% of asymptomatic individuals. CT scanning is the modality of choice, however, in specific circumstances such as in the evaluation of a patient in intensive care, when complications are suspected, or in the preoperative evaluation of surgical candidates.
