Abstract

Our study aims to determine diagnostic reference levels (DRL) for chest front examination in postero anterior (PA) for optimizing patient entrance surface dose (ESD) and dose-area product (DAP) of patients in west of Cote d’Ivoire. 90 patients from three hospitals undergoing conventional radiology were considered. The ESD and DAP for each patient were obtained during chest radiography (PA) examination. The measurements were performed with the device call Dose-Area Product-meter (DAP-meter) with brand Diamentor M4-KDK, type 11017. The DRL were obtained in applying the 75th percentile statistical method to the obtained ESD and DAP. The obtained DRL in ESD for chest radiography for all rooms is 0.40 mGy and in DAP is 54.85 cGy⋅cm2. Our DRL for ESD is higher than those obtained in Abidjan District and in other countries like UK and Cameroon. Our DRL for DAP is higher than those from Abidjan and all other countries for which a similar study was made. The comparison of these values to those from Abidjan and other countries, shows us that radiology technicians can make efforts to choose radiological parameters to reduce ESD. They must use convenable the X-rays tube to reduce DAP by reducing the patient exposure surface.
西部Côte科特迪瓦胸部x线诊断参考水平
本研究旨在确定后前路(PA)胸前检查的诊断参考水平(DRL),以优化科特迪瓦西部患者的患者入口表面剂量(ESD)和剂量面积积(DAP)。对来自三家医院接受常规放射检查的90名患者进行了研究。在胸片(PA)检查时获得每位患者的ESD和DAP。使用Diamentor M4-KDK(11017型)品牌的剂量面积产品计(DAP-meter)进行测量。对所得的ESD和DAP采用75百分位统计方法计算DRL。所有房间胸片在ESD下的DRL为0.40 mGy,在DAP下的DRL为54.85 cGy·cm2。我们的可持续发展教育DRL高于阿比让地区以及英国和喀麦隆等其他国家的DRL。我们对DAP的DRL高于阿比让和所有其他进行类似研究的国家。这些数值与阿比让和其他国家的数值比较,表明放射技术人员可以努力选择放射参数来降低ESD。他们必须使用方便的x射线管,通过减少患者的暴露面来减少DAP。
