目的：研究在不同介入治疗过程中受检者和医生的受照剂量，探讨影响辐射剂量的因素及其减少辐射剂量的途径和方法。方法：选择广西4家三甲医院开展的冠状动脉造影、脑血管造影和肝动脉栓塞术3种介入治疗手术共67例患者，采用热释光剂量计元件贴敷在受检者和医生体表处，测量不同部位受照体表剂量，并进行统计分析。结果：冠状动脉造影手术、肝动脉栓塞术和脑血管造影手术中患者最高表面受照剂量分别为13.35 mSv、17.75 mSv和107.18 mSv；在3种介入手术中，医生眼睛部位、左手和左脚表面受照剂量均较其他部位大，有防护情况下受照剂量低于无防护条件下受照剂量。结论：在不同手术中同一部位表面受照剂量相差较大，在同一手术中各部位表面受照剂量同样存在较大差异。在介入手术治疗中需增强辐射防护意识，以减少医生和患者的医疗照射。%Objective: To investigate the radiation dose of operators and patients during therapeutic interventional procedures, analyze the factors which influence radiation dose as well as the way to decrease dose, and strengthen radiological protection. Methods: A total of 67 interventional procedures from the 4 Top Three hospitals in Guangxi province were selected, including coronary angiography surgery, cerebral angiography and hepatic artery embolization. Theromoluminescence dosimeter was used to measure the X-ray radiation dose of operators and patients in different position and exposed surface dose of different body parts. Results: Surface dose was different at the same body parts in the different interventional procedure as well as the different parts in the same interventional procedure. The maximum surface radiation dose in the patients in Coronary angiography surgery, Cerebral angiography and hepatic artery embolization was respectively 13.35 mSv, 17.75 mSv and 107.18 mSv. Surface radiation dose to eyes, left hand and left foot was larger than the other parts in the three kinds of interventional procedures. Furthermore, radiation dose under protection was less than which without protection. Conclusion:We should strengthen the non-surgical interventional radiology projection, especially shielding sensitive body part in patients. In addition operator should enhance the awareness of radiation protection and operational proficiency, to reduce occupational exposure and medical exposure of patients.
