The effective radiation of each scan was calculated in millisieverts (mSv), based on dose-length product (DLP) reported by the CT scanner and using a conversion factor obtained from Table3of the Report No. 96 of the American Association of Physicists in Medicine [29]. The use of DLP to ...
Paranasal sinuses computed tomogram (CT) scan are important for functional endoscopic sinus surgery (FESS) as their information assist the surgeon in pre-operative planning. This study aimed to show importance of CT scan in evaluation of anatomical variations to prove a correlation with disease ...
