BACKGROUND
This study was conducted to measure the entrance skin dose in radiographic examinations of pediatric patients in King Khalid Hospital, Majmaah, Saudi Arabia.
INTRODUCTION
Children have been given special attention since they are often regarded as especially vulnerable to potential hazards. The pediatric population is more susceptible to radiation than the adult population for certain tumor types.
OBJECTIVE
The aim of this study is to determine the amount of Entrance Surface Dose (ESD) received by pediatric patients attending the emergency department.
METHODS
Traumatic department registers for pediatric patients admitted to the King Khalid hospital (Majmaah, Saudi Arabia) between 1st February and 31st December 2018 were retrospectively studied for all diagnostic (plain radiographs examinations) imaging did on pediatric (<18 years old) trauma patients. The entrance surface dose was used to calculate the total radiation dose for each patient. One hundred and twenty patients encountered the inclusion criteria of the study and their doses (chest, skull, and extremities) were assessed.
RESULTS
The mean of radiation exposure factors were 65.4 ± 7.9 (71.3 - 89.9) and 1.3 ± 0.2 (0.3-2.5) for X-ray tube potential (kVp) and current (mAs), respectively. The measured dose for pediatric patients were 0.10 ± 0.02 (0.09 - 0.37), 0.18 ± 0.04 (0.06 -0.59) and 0.09 ± 0.03 (0.03 -0.45) for chest, skull, and extremities, respectively. The mean Entrance surface dose received by trauma patients was 0.03-0.59 mGy. 51.7% (62 patients) of the patients received ≤ 0.25 mGy while around 48.3% (58 patients) received ≥ 0.26 mGy radiation dose from those examinations.
CONCLUSION
Trauma patients attending to traumatic radiology department obtain substantial Entrance surface dose from chest, skull, and extremities imaging procedures within their initial assessment. The radiation exposure can also be lowered by optimizing each examination, therefore more studies are recommended for this task. The results obtained can be used as the basis for local reference dosages for X-ray examinations.
背景
本研究旨在测量沙特阿拉伯迈马阿的哈利德国王医院儿科患者放射检查的入口皮肤剂量。
介绍
由于儿童被视为特别容易受到潜在危害的人群，因此他们受到了特别关注。与成人相比，某些肿瘤类型的儿科人群更容易受到辐射。
目的
本研究旨在确定接受急诊的儿科患者的入口表面剂量（ESD）量。
方法
对 2018 年 2 月 1 日至 12 月 31 日期间在哈利德国王医院（迈马阿，沙特阿拉伯）就诊的儿科（<18 岁）创伤患者的所有诊断（普通射线照相检查）成像进行回顾性研究。使用入口表面剂量来计算每位患者的总辐射剂量。有 120 名患者符合本研究的纳入标准，评估了他们的剂量（胸部、颅骨和四肢）。
结果
X 射线管电压（kVp）和电流（mAs）的平均辐射暴露因素分别为 65.4 ± 7.9（71.3-89.9）和 1.3 ± 0.2（0.3-2.5）。儿科患者的测量剂量分别为 0.10 ± 0.02（0.09-0.37）、0.18 ± 0.04（0.06-0.59）和 0.09 ± 0.03（0.03-0.45），用于胸部、颅骨和四肢。创伤患者的平均入口表面剂量为 0.03-0.59 mGy。51.7%（62 名患者）的患者接受的剂量≤0.25 mGy，而约 48.3%（58 名患者）的患者接受的剂量≥0.26 mGy 来自这些检查。
结论
在最初评估中，接受创伤放射学部门的创伤患者从胸部、颅骨和四肢成像程序中获得大量入口表面剂量。通过优化每次检查，可以降低辐射暴露，因此建议进行更多研究。获得的结果可用作 X 射线检查的本地参考剂量的基础。
