Estimation of Effective Radiation Dose During CT K.U.B

Abstract

CT is an x-ray procedure that generates high quality sectional images of the body, these images provide more detailed information than normal x-ray images, but CT gives patients high radiation exposure compared to conventional x-ray devices. The the main objective of this study to estimate the effective radition dose during CT KUB CT scan. In this study the effective radiation dose was estimated for patients underwent KUB CT scan in three hospitals in Khartoum state (November February 2020). The data was collected form scan of 90 adult patients during KUB CT scan perfomed by different CT scanners (Toshiba 64 slice, Siemens 32 slice, Toshiba 16 slice), the CTDI, DLP were used to estimate effective radiation dose received by patients. The result of this study showed that the mean effective dose in CT devices (Toshiba 64 slice), (Siemens 32 slice) and (Toshiba 16 slice) (8.23± 0.68) mSv, (4.82±1.95) mSv and (4.14±1.33) mSv respectively and total mean effective dose in this study is (5.7 ±1.32) mSv. In this study found that the effective radiation dose received by patient from CT scanner 64 slices is higher than CT scanner 32 slices and CT scanner 16 slice, this differencedue to the difference in protocols of scan used.
