چکیده
A technique for three-dimensional (3D) computed tomography (CT) of the paranasal sinuses was evaluated. The influence of milliamperage and reconstruction algorithms on image quality was studied in a phantom. Eleven patients with bony abnormalities of the paranasal sinuses underwent CT to assess the clinical impact of 3D CT protocol. Contiguous 1.5-mm sections obtained at 120 kVp/175 mA/1.9 sec can provide 3D images with high diagnostic image quality. This technique offers the advantage of a much lower dose than that of the conventional CT (CCT) examination of paranasal sinuses. Three-dimensional CT protocol of paranasal sinuses is suggested for use for the evaluation of bony abnormalities and for preoperative planning of the above region.

Image Optimization and reduction of radiation dose in CT of the paranasal sinuses
Introduction: Since demand for computed tomography (CT) examinations is growing, patients are exposed more frequently to ionizing radiation. To reduce the dose delivered to patients in each scan, CT technologists can change the image acquisition parameters. However, this reduces image quality. Present study aimed to optimize and reduce radiation dose in a CT of the paranasal si...
متن کاملImportance of Paranasal Sinuses in Computational Modeling of Nasal AirFlow
This paper investigates the importance of including paranasal sinuses in the computational modeling of the nasal airflow. Three dimensional models of human nasal airway with and without including paranasal sinuses were reconstructed from Computed tomography (CT) axial images of a subject with healthy nasal airway. The reconstruction process was performed using MIMICS® software program. The airw...

متن کاملTwo- and Three-Dimensional Anatomy of Paranasal Sinuses in Arabian Foals
The 2- and 3-dimensional (3D) anatomy and the morphometric properties of the paranasal sinuses of the foal have received little or no attention in the literature. The aim of this study was to obtain details of the paranasal sinuses using multiplane CT imaging to create 3D models and to determine morphological and morphometric data for the sinuses using the 3D models. The heads of five female fo...
متن کاملThe sinonasal communication in the horse: examinations using computerized three-dimensional reformatted renderings of computed-tomography datasets
BACKGROUND Sinusitis is a common disease in the horse. In human medicine it is described, that obstruction of the sinonasal communication plays a major role in the development of sinusitis. To get spatial sense of the equine specific communication ways between the nasal cavity and the paranasal sinuses, heads of 19 horses, aged 2 to 26 years, were analyzed using three-dimensional (3D) reformatt...
