BACKGROUND
Computed Tomography has become the major source of population exposure in diagnostic x-rays. This concerned issue will be resolved by stetting Local Diagnostic Reference Levels.
OBJECTIVES
The main objective of this study is to assess dose indicators for the establishment of Local Diagnostic Reference Levels.
MATERIALS AND METHODS
prospective cross-sectional study design was conducted on 8 public and private hospitals performing CT examinations. A total of 725 adult patients who underwent abdominopelvic, chest, and head CT examinations were evaluated from October 2021 to March 2022. Patients' demography, exposure parameters, and dose descriptors were collected. The minimum, maximum, mean, median, and third quartile values were analyzed using Finally, the third data were compared with national and international values.
RESULTS
The third quartile values obtained from median of volumetric (mGy) and (mGy.cm) which are considered as local DRLs for head, chest, and abdominopelvic CT examination, respectively, were 53 mGy, 14 mGy and 13 mGy 1307 mGy.cm, 575 mGy.cm, and 932 mGy.cm.
CONCLUSION
The results of this study showed that practices of CT imaging in both public and private hospitals in Addis Ababa were comparable to other national and international values.
背景
计算机断层扫描已成为诊断性X射线中人群辐射暴露的主要来源。通过设定当地诊断参考水平，这一令人担忧的问题将得到解决。
目的
本研究的主要目的是评估用于建立当地诊断参考水平的剂量指标。
材料与方法
对8家进行CT检查的公立和私立医院进行前瞻性横断面研究设计。2021年10月至2022年3月，共评估了725例接受腹部盆腔、胸部和头部CT检查的成年患者。收集患者的人口统计学信息、暴露参数和剂量描述符。最后，使用……分析最小值、最大值、平均值、中位数和第三四分位数，并将数据与国家和国际值进行比较。
结果
分别从容积剂量（mGy）和剂量长度乘积（mGy.cm）的中位数获得的第三四分位数，分别被视为头部、胸部和腹部盆腔CT检查的当地诊断参考水平，分别为53 mGy、14 mGy和13 mGy，1307 mGy.cm、575 mGy.cm和932 mGy.cm。
结论
本研究结果表明，亚的斯亚贝巴公立和私立医院的CT成像实践与其他国家和国际值相当。
