Title: Radiological examination frequency and collective effective dose from pediatric computed tomography (CT) in Sudan
Author: Mohammed ,Mohammed Ibrahim Abdoelgabbar
Abstract: Abstract The pediatric medical imaging using ionizing radiation requires special attention in terms of radiation protection for risk of cancer. The use of CT in medical imaging cause the high value of radiation doses to patients and the public for that to be a measure of dose and try to decrease as much as possible. The study aimed to assess the frequency and collective effective dose for populations from pediatric CT procedures in Sudan. The annual collective dose form pediatric CT examination had been calculated by a survey done at 10 hospitals providing data of examination frequency per month. The annual examination frequency and annual collective effective dose had been calculated by multiplying the effective dose of each examination by the frequency. The results were calculated and discussed providing that the annual collective effective dose from pediatric CT examinations is (169 man.Sv). The highest percentage examination frequency was for abdomen (32%).The highest percentage contribution to total to the total dose from pediatric CT examination was for abdomen (49%).The calculated annual examination frequency and annual collective effective dose had been compared with the results of literature and other studies to evaluate the estimated values. This value of dose (196 man.Sv) far less than (500man.Sv) the dose which is set by the scientific resources.
