Abstract
CT is the primary modality used to evaluate patients with NP, but MR does have an occasional role. Conventional radiographs are no longer within the standard of care for the evaluation of the paranasal sinuses. Modern helical multislice CT scanners can produce reconstructed images of diagnostic quality in any plane of imaging. Cystic fibrosis patients have preferential opacification of the paranasal sinuses, whereas non-CF patients with NP have preferential opacification of the nasal cavity. On MRI, fungal infection may have very low signal on T2-weighted images, and may thus mimic aerated sinuses.
