Estimation of Radiation Effective dose for pediatric patients in Brain Computed tomography

Abstract

Computed Tomography (CT) of the pediatric for brain it used increasingly. Particularly in oncological patients. How to use CT scan rightly and to reduce the radiation dose as much as possible have been the critical issues of concern in the field of clinical imaging technology. In diagnostic radiology, periodic dose assessments are carried out to encourage the optimization of the radiation protection of patients. This study estimated radiation dose to 51st pediatric patients in Modern Medical Center by undergoing GE Optima CT250 series - 16 slices. The result of this study the Linear Regression equation between CTDIvol and SSDE which is SSDE = -0.002+0.93(CTDIvol) And mean ± SD for effective dose it’s 49.69 msv ± 29.82 msv comparing with Korean stander which is 1.5 msv ± 0.2 msv it’s high . This study concludes to deference referring to not used pediatrics protocol.
