目的 探讨心脏专用数字平板DSA机器和多用途数字平板DSA机器在标准8体位冠状动脉造影术的辐射剂量对比.方法 用西门子AXIOM Artis-dfc心脏专用数字平板DSA机器随机记录患者50例、用GE Innova IGS530多用途数字平板DSA机器随机记录患者50例,最后用15 cm厚的有机玻璃体模加线对测量卡对两机器再做一次标准8体位冠状动脉造影;用20 cm厚的有机玻璃体模加线对测量卡对两机器在介入参考点位进行正位透视和电影采集,对取得的数据进行对比分析.结果 西门子机器累计剂量CD(cumulative dose)值是153.7 mGy、剂量面积乘积DAP(dpsearea product)值是11.42 mGy·cm2;GE机器累计剂量CD(cumulative dose)值是410 mGy、剂量面积乘积DAP(dpse area product)值是37.22 mGy·cm2.结论 心脏专用数字平板DSA机器辐射剂量明显小于多用途数字平板DSA机器.“,”Objective To discuss the radiation dose contrast between heart special FD DSA machine and FD DSA machine in the standard 8 position coronary artery angiography.Methods 50 cases were rearded with siemens AXIOM-Artisdfc heart FD DSA machine while the same samples with GE Tnnova IGS530 FD DSA machine.Todo stardard 8 position coronary artery angiography was done with 15 cm thick organic vireous die line measurement card for the two machines again.And then normal perspective and movie collection was done with 20 cm thick organic vitreous die line measurement card for the two machinesin referfnce point.At last the data was analyzed.Results The value of cumulative dose for simens and GE were 153.7 mGy and 410 mGy respectively.The value of dpse-area product for simens and GE were 11.42 mGy * cm2 and 37.22 mGy * cm2 respectively.Conclusion The radiation dose of the heart FD DSA machine was obviously less than that of the FD DSA machine.
