Abstract

This study has established local diagnostic reference levels (LDRLs). Dose report and scan parameters for abdomen was assessed during the period of seven months at the three study centres. Data on CT Dose index (CTDIw) and dose length product (DLP) available and achieved on CT scanner control console was recorded for a minimum of 10 average sized patients for each facility to established a local Diagnostic reference level (LDRLs) and radiation dose optimization Data was collected using a purposive sampling technique, from 131 adult patients weighing 70±3 kg) from Philip brilliance, Toshiba Alexion and General Electric (GE) CT scanners for this study. Third quartile values of the estimated LDRLs for CTDIw and DLP was determined as 12.7 mGy and 560 mGy*cm. The mean CTDIw obtained are lower to the reported data from the European Commission of 35 mGy. The mean DLP are comparably lower than all the reported value from the European commission of 780 mGy/cm. Therefore, there is no any clinical implication and hence CT dose optimization is recommended.
