摘要
目的建立本机构介入诊断与治疗典型值,以此为工具评估患者医疗暴露剂量,并进行放射防护措施优化。方法2023年6月—12月,采集593台成人心血管介入诊疗手术的信息,包括手术类型、设备型号、空气比释动能-面积乘积(KAP),入射参考点空气比释动能(Ka,r)和透视时间(FT)、曝光模式。结果2023年度本机构的心血管介入诊断的典型值为27.5 Gy·cm^(2);心血管介入治疗的典型值为70.0 Gy·cm^(2)。介入治疗手术的透视时间、KAP值、Ka,r值均显著高于介入诊断(P<0.01)。透视时间、KAP值、Ka,r值间有显著相关性(P<0.01)。结论本研究结果与其他研究差别较小,为北京市心血管介入诊断与治疗剂量水平提供了典型数据参考值,有助于不同医疗机构之间实现剂量优化。
Objective To establish typical values for interventional diagnosis and treatment at our institution,use these values as a tool to evaluate patient medical exposure doses,and optimize radiation protection measures.Methods From June to December 2023,we collected information on 593 adult cardiovascular interventional diagnosis and treatment surgeries,including surgery type,equipment model,air kerma-area product(KAP),incident reference point air kerma(Ka,r),perspective time(FT),and exposure mode.Results The typical value of cardiovascular interventional diagnosis at our institution in 2023 was 27.5 Gy·cm^(2).The typical value of cardiovascular interventional treatment was 70.0 Gy·cm^(2).The FT,KAP,and Ka,r of interventional surgeries were significantly higher than those of interventional diagnosis(P<0.01).There were significant correlations between FT,KAP,and Ka,r(P<0.01).Conclusion The results of this study were slightly different from those of other studies.They provide typical data and reference values for cardiovascular interventional diagnosis and treatment dose levels in Beijing and are helpful for dose optimization between different medical institutions.
