Abstract
Radiation doses associated with Computed Tomography is higher than the corresponding doses associated with x-ray examinations by more than one hundred. The research study aims to evaluate the radiation doses associated with CT examinations in examinations in Hospital A in one of the radiology departments. This hospital participated in a dose survey for the three most commonly used CT protocols. CT dose indices are calculated and shown by CT machine via Picture archiving communication system. The volume CT dose index , dose-length product , and effective dose for the head were 48.7 mGy, 600 mGy.cm, and 1.38 mSv; for the chest, 15.5 mGy, 349 mGy.cm and 4.89 mSv; for the abdomen- pelvic, 14 mGy, 551 mGy.cm, and 5.3 mSv. The diagnostic reference dose levels were lower than those of international organizations. The study concluded that the effective doses for head, chest and abdomen pelvic are calculated and can be used as additional tools to verify the quality control of CT scanners. Conclusion: The Effective doses the abdomen – pelvic CT protocol is reduced to 55% due to decrease the tube current – product time from 224 mAs to 182 mAs
