Abstract:
Using of Computed Tomography in medical diagnosis delivers high radiation dose to patients comparing with other radiological procedures. Lake of optimizing protocols could be increasing the patients radiation dose. The aim of this study to evaluate the radiation dose to patients during paranasal sinuses Computed Tomography Examinations.the data were collected from Ibn EL haitham Diagnostic Center in period from February to August 2018. A total of 50 patients were examined in CT department with Toshiba machine 4 slices. The amount of radiation dose that received from CT scan depends on dose parameters CTDIvol and DLP.
The result of the study revealed that the patients dose obtained from CT Para nasal sinuses examinations presented as mean ± standard deviation, were the
patients age was 38.38 ±17.16 ,KVP 120.00±ooo, mA100.54±24.94 , exposure2388.07±3205.41,CTDIvol52.7±25.1mGy,DLP 577.1±267.43mGy.cm and ED 8.66±4.0114 mSv .
The study concluded that the selection of the most appropriate imaging modality should be performed in view of the delivered doses, required image quality and information and the clinical circumstances
