Abstract


This study aims to determine the comparisson between the radiation dose of computed tomography dose index volume (CTDIvol) and size-specific dose estimate (SSDE) in CT scan thorax for Corona Virus Disease 2019 (Covid-19) and non-Covid-19 patients. The method used in this study is a retrospective study, where the data used is obtained from images of CT Scan thorax examinations of past COVID and non-COVID patients. The amount of data used was 70 for each examination. Furthermore, the CTDIvol and SSDE values were analyzed with IndoseCT software, and then two independent sample T-test statistics were performed with IBM SPSS software. Based on the results of this study, there is a difference between the doses of CTDIvol and SSDE in the thorax CT scan examination of COVID and non-COVID patients. The difference is that the mean CTDIvol dose for COVID patients is 7,901.29 mGy, and for non-COVID patients is 4,902.11 mGy, with a p-value of 0.010. Meanwhile, at the SSDE dose, the mean for COVID and non-COVID patients was (11.02 × 1.34) mGy and (7.50 × 2.77) mGy, respectively, with a p-value of 0.001. Based on these results, it can be concluded that the average dose for COVID patients is greater than that for non-COVID patients; both have a significant difference.
