Because of the interest in reducing the time and radiation required for screening sinuses
with CT, we compared the quality of conventional coronal CT images with coronally …

Materials and Methods The following comparative phantom skull studies were performed for
evaluation of stair-step artifact, using a skull encased in Perspex (Imperial Chemical …

Paranasal sinuses of 52 patients with sinusitis, tumours or fibrous dysplasia were scanned.
Axially acquired spiral data were obtained and reconstructed coronally. Four radiologists …

While computed tomography (CT) has become an important imaging modality in the
evaluation of the paranasal sinuses, the radiation dose remains higher than is necessary …

5 patients were examined with the conventional mode and 5 patients with spiral-CT.
Technical factors for the conventional mode were 250 mAs, a slice thickness of 4 mm and an …

The number of screening examinations of the sinuses performed with CT has markedly
increased owing to the widespread and increasing use of endoscopic sinonasal surgery. We …

Materials and Methods Thirty-four consecutive adult patients being evaluated for sinusitis
over a 6-month period were studied by CT. Most patients were being evalu-ated because of …

Computed tomography has improved the visualization of paranasal sinus anatomy and has
allowed greater accuracy in evaluating paranasal sinus disease. Because of the great …

Objective: This study aims to compare the image quality and potential diagnostic accuracy of
paranasal sinus CT scans generated by flat panel cone beam CT at three specific data …

CT scanning has allowed the radiologist to image paranasal sinus disease with an accuracy
and detail never before attainable. This information has made the imager an important …
