Assessment of Radiation Dose of Pediatric and Adult patients for Computed Tomography Examination

Abstract

The important of this study comes from the increased number of CT procedures to adult and pediatric as CT consider invasive investigation. Patient data for both male and female collected from four different hospital and centers in Khartoum which using different CT scanner modalities. The data of this study were collected from Alya Hospital (Toshiba, 64 slice), Ibn Alhitham specialist (Toshiba, 4 slice), Alzytouna Hospital (Toshiba, 64 slice) and Modern center (GE, 16 slice). it preformed for brain and chest in adult and pediatric patients Comparing the dose parameters among the two exams for all hospitals for brain the CTDIvol, DLP and ED was 76.82 ± 16.07, 2199.45 ± 1789.7 and 4.62 ± 3.76 respectively, while for CT chest was 32 ± 11.33, 837.59 ± 338.54 and 11.75 ± 4.8 respectively in adults. When Comparing the dose parameters(CTDIvol, DLP and ED) among the two exams for all hospitals for brain the CTDIvol, DLP and ED was 53.4 ± 9.7, 861.9 ± 268 and 7.58 ± 2.83 respectively, while for CT chest was 8.69 ± 2.78, 302.22 ± 161.75 and 7.8 ± 4.05 respectively for pediatric. Finally the radiographic data show that ED for adult male were higher than adult female as it is for pediatric male expect the CTDIv were higher for pediatric females than males.
