Paranasal sinus pathoses on cone beam computed tomography
PURPOSE The aim of this study was to investigate paranasal sinus pathoses detected on cone-beam computed tomography (CBCT) in an adult population. PATIENTS AND METHODS Three observers retrospectively inspected 353 consecutive CBCT scans obtained in a dentomaxillofacial radiology department for paranasal sinus pathoses. Descriptive statistics and chi-square tests were used to determine the pre...
متن کاملLocal Diagnostic Reference Levels for Common Computed Tomography Procedures at a Tertiary Hospital in South Africa
Introduction: An operational computed tomography (CT) scanner is a major source of human exposure to ionizing radiation. Exposure increases the risk of cancer and aplastic anaemia. All radiation exposures should be justified and optimized to meet the clinical objective. In order to avoid the administration of excessive radiation dose to patients, diagnostic reference l...
متن کاملEvaluation of paranasal sinus mucosa in coal worker's pneumoconiosis: a computed tomographic study.
OBJECTIVE To evaluate by computed tomographic scanning the paranasal mucosal changes of coal workers with and without pneumoconiosis. METHODS Examination of images and scores from paranasal computed tomographic scans. The study participants were 26 coal workers with pneumoconiosis, 29 coal workers without pneumoconiosis, and 20 controls. All were men. The extent and patterns of inflammatory p...
متن کاملUnilateral Paranasal Sinusitis Detected by Routine Sinus Computed Tomography: Analysis of Pathology and Image Findings
The aim of this study was to evaluate the histopathological findings of unilateral paranasal sinus disease dominated by maxillary sinus opacification on routine non-contrast enhanced paranasal sinus CT. We performed a retrospective analysis of routine paranasal sinus CT conducted between March 2003 and April 2007. Unilateral maxillary sinus opacification (with or without ipsilateral ethmoid or ...
متن کاملRadiographic evaluation of maxillary sinus by computed tomography.
The radiographic appearance of the paranasal sinuses is less accurate in infants and children than in adults, as in infants the cavities are smaller and the margins of the healthy sinuses are often indistinct Moreover, the details of the infantile cranial bones themselves are not sharp owing to the lesser contrast in density between relatively thin bones and soft tissues of the infantile skull ...
