| 目的 调查北京地区成人介入放射诊疗手术的辐射剂量相关数据,为建立北京地区介入放射诊疗诊断参考水平(DRL)提供依据。方法 对北京地区30家医疗机构进行调查,涵盖介入放射诊疗手术类型包括:冠状动脉、结构性心脏病、永久性起搏器、电生理射频消融、神经系统、腹部系统、下肢血管,以空气比释动能面积乘积(PKA)和入射参考点空气比释动能(Ka,r)作为主要调查参数,取75%位数作为DRL值,基于整体水平和医疗机构水平分析DRL。结果 此次调查共收集7类介入放射诊疗手术病例3 331例。诊断检查的DRL(PKA和Ka,r)分别为冠状动脉(37.87 Gy·cm2、509.00 mGy)、电生理检查(9.34 Gy·cm2、48.00 mGy)、神经介入检查(218.50 Gy·cm2、901.70 mGy)、腹部介入检查(81.00 Gy·cm2、302.20 mGy)、下肢介入检查(83.37 Gy·cm2、214.69 mGy)。介入治疗(含诊断和治疗)的DRL(PKA和Ka,r)分别为冠状动脉(135.00 Gy·cm2、1 897.58 mGy)、结构性心脏病(26.91 Gy·cm2、172.30 mGy)、永久性起搏器(27.77 Gy·cm2、87.75 mGy)、电生理射频消融(34.46 Gy·cm2、247.00 mGy)、神经介入(214.36 Gy·cm2、12 82.80 mGy)、腹部介入(196.64 Gy·cm2、875.71 mGy)、下肢介入(108.25 Gy·cm2、523.25 mGy)。结论 本研究经调查统计得到北京地区介入放射诊疗的辐射剂量DRL,部分介入放射诊疗程序需加强放射防护最优化。 |

| Objective To investigate the relevant data on radiation dose in interventional radiodiagnosis and radiology of adults in Beijing and to provide a basis for establishing relevant diagnostic reference levels (DRLs) in this region. Methods A total of 30 medical institutions in Beijing were surveyed, covering interventional radiodiagnosis and radiology surgeries for coronary artery, structural heart diseases, permanent cardiac pacemaker implantation, electrophysiological study and radiofrequency ablation, nervous systems, abdominal systems, and the blood vessels of the lower limbs. The primary parameters investigated included the air kerma area product (PKA) and incident air kerma (Ka,r). The 75th percentiles of radiation dose were considered DRLs, which were analyzed at both the overall and individual medical institution levels. Results A total of 3 331 cases of the abovementioned radiodiagnosis and radiology surgeries were collected. The DRLs (i.e., PKA and Ka,r) of various diagnostic examinations were 37.87 Gy·cm2 and 509.00 mGy for coronary artery, 9.34 Gy·cm2 and 48.00 mGy for electrophysiological study and radiofrequency ablation, 218.50 Gy·cm2 and 901.70 mGy for nervous systems, 81.00 Gy·cm2 and 302.20 mGy for the abdominal system, and 83.37 Gy·cm2 and 214.69 mGy for the blood vessels of the lower limbs. In contrast, the DRLs (i.e., PKA and Ka,r) for interventional radiodiagnosis and radiology were determined at 135.00 Gy·cm2 and 1 897.58 mGy for coronary artery, 26.91 Gy·cm2 and 172.30 mGy for structural heart diseases, 27.77 Gy·cm2 and 87.75 mGy for permanent cardiac pacemaker implantation, 34.46 Gy·cm2 and 247.00 mGy for electrophysiological study and radiofrequency ablation, 214.36 Gy·cm2 and 1282.80 mGy for the nervous system, 196.64 Gy·cm2 and 875.71 mGy for abdominal system, and 108.25 Gy·cm2 and 523.25 mGy for the blood vessels of the lower limbs. Conclusions The DRLs of radiation dose in interventional radiodiagnosis and radiology in Beijing were determined through a survey and statistic analysis. These findings suggest that for certain interventional procedures, the optimized radiation protection should be enhanced. |
