摘要
目的：测量出血性脑血管病在介入放射学诊疗过程中患者及介入医生所受到的X线辐射剂量，分析探讨影响X线辐射剂量的因素及其减低剂量的途径和方法。方法：应用热释光测量法对我院介入中心近期120例出血性脑血管病进行介入放射学检查和（或）介入治疗时患者及介入医生辐射剂量测量。结果：出血性脑血管病患者行全脑血管造影时患者皮肤剂量范围在0．013～4．032Gy，介入医生所受剂量范围在0．113～1．601mGy；行栓塞治疗时患者皮肤剂量范围在2．231～10．868Gy，介入医生所受剂量范围在0．307～2．548mGy。结论：全脑血管造影是诊断出血性脑血管病的金标准，介入治疗是治疗脑血管病的重要而有效的方法之一，但患者及介入医生所受的X线辐射剂量很大，因此应该采取有效的防护措施来减低X线辐射剂量。
Objective：To investigate the X-ray radiation dosage of patients and physicians in the interventional examination and embolization in haemorrhagic cerebrovascular disease and analyze the factors which influence X-ray radiation dosage as well as the ways to decrease the dosage. Methods： Thermoluminescence was used to measure the X-ray radiation dosage of patients and physicians in the interventional examination and embolization in haemorrhage cerebrovascular disease of 120 cases in our department. Results： The dosage of skin in the patients who accepted spinal angiography was 0. 013 4. 032Gy, while the dosage of skin in the physicians was 0.113 - 1. 601mGy. The dosage of skin in the patients who accepted interventional embolization was 2. 231-10. 868Gy,while the dosage of skin in the physicians was 0. 307-2. 548mGy. Conclusion：Cerebrovascular angiography is the golden standard for diagnosing haemorrhagic cerebrovascular disease and interventional embolization is now looked upon as an important therapeutic tool for cerebrovascular disease. But,since in the interventional examination and embolization both the patients and physicians are exposed to too much X-ray radiation,more effective protection measures should be taken to decrease the X-ray radiation dosage accepted by patients and physicians.
