摘　　要：Objectives: To investigate the dose delivered to adult patients during cranioencephalic and abdominal-pelvic examinations in computed tomography (CT) in order to set up the Local Dosimetric Reference Levels (LDRLs) of the University Hospital of Treichville (UHT) for the radiation protection of patients undergoing CT scans. Methods: This study was prospectively performed on 153 CT images of adult patients including 120 CT images of cranioencephalic (CE) and 33 CT images of the abdominal pelvic (AP) examinations. These images were acquired on the CT system INSITUM with 64 bars, manufactured by the company SINOVISION and commissioned in 2021 at UHT. Then the volume computed tomography index (CTDIvol) and the dose-length product (DLP) were determined. Results: Based on the statistical method of 75th percentile, the obtained LDRLs as CTDIvol and DLP are 54.37 mGy and 28.07 mGy, 1716 mGy.cm and 1490.8 mGy.cm respectively for CE and AP examinations. Comparing our results with those from different international studies, CTDIvol and DLP values obtained in the present work are higher. Conclusion: LDRLs for dosimetric quantities such as CTDIvol and DLP for CE and AP examinations have been set up in this study. It will contribute with further studies to the national diagnostic reference levels of cranioencephalic and abdominal pelvis CT exams for strengthening the radiation protection of patients in Côte d’Ivoire.Objectives: To investigate the dose delivered to adult patients during cranioencephalic and abdominal-pelvic examinations in computed tomography (CT) in order to set up the Local Dosimetric Reference Levels (LDRLs) of the University Hospital of Treichville (UHT) for the radiation protection of patients undergoing CT scans.
