Estimation of Effective Dose for Pediatric Patients During Computed Tomography Examinations

Abstract

This research aim to estimate the effective dose for pediatric during common Computed Tomography exanimations ( brain , Chest , abdomen and pelvis ) , at five different hospitals in Khartoum state – Sudan ( Modern Medical Center , NeileenMedical Diagnostic Center , Police Hospital , Alzytouna Hospital and Ibn alhytham) by using equation , is presented, the gender distributed according to selected CT scan were the total number of patients was 1048 patients years , approximately 45% of the patient for brain (386 ; 233 males and 153 female) , about 22% for chest (191 ; 121 males and 70 female), about 10% for CT abdomen (283; 163males and 120 female) and 21% for pelvis CT (188; 102 males and 86 female) with total number of male and female 619 and 429 respectively. The effective dose found 1.93 mSv for brain (1.98 mSv for male and 1.87 mSv for female),in CT Chest the effective dose was 3.58 mSv (3.57 mSv for male and 3.59 mSv for female), for abdomen was 5.69mSv (5.25 mSv for male and 6.13 mSv for female) and for pelvis the effective dose found 7.14 mSv (8.04 mSv for male and 6.23mSv for female). This study recommends that the CT technologist should be aware to achieving the optimization of patient’s dose using the best strategies available for reducing radiation dose, and the patient’s Dose must be monitored regularly
