The contribution of renal , liver , bone and thyroid examinations to the pediatric effective dose and percentage cancer risk factor were 1.874mSv (0.026%) , 0.3947 mSv (0.022%) , 2.1031mSv (0.0105%) and 1.5753mSv (0.078%) respectively. The mean effective dose equivalent per pediatric patient in this study was 1.4867 mSv.
Regarding to computed tomography scanning , The highest effective dose was recorded from GE scanner (19.9 mSv) for chest scan at 240 mAs and 120 kVp , while the smallest effective dose was recorded by Siemens (0.3 mSv) for brain scan at the same previous values of mAs and kVp.
This study also reveals The percentage risk factors due to brain scan with the three different scanners are: 0.088 , 0.031 and 0.016 for GE , Philips and Siemens respectively, it’s clear that GE brain scanner will produce high risk factor compared with the two others , this is of course due to the high effective dose produced by this scanner.
