摘　　要：采用穿透电离室型剂量测量系统,对在某医院行脑血管介入放射学操作的130例患者所受的辐射剂量进行了测量。结果表明,造影组的剂量面积乘积和累积剂量分别为(17937±15874)cGy·cm2和(759±958)mGy,栓塞组的剂量面积乘积和累积剂量分别为(28119±17828)cGy·cm2和(1335±717)mGy,栓塞组明显高于造影组。在所研究的130例患者中,约有4.6%的患者累积剂量超过2Gy,主要是脑血管栓塞术患者,提示要加强对这些患者的防护。By using a dose measurement system equipped in digital subtraction angiography, the radiation dose data were collected on 130 instances of cerebral vessels interventional radiology procedures at a hospital. The resuhs showed that the dose values of DAP, CD in angiography group were respectively （ 17 937 ± 15 874） cGy·cm^2, （759 ± 958） mGy; and in embolisation group were （28 119 ± 17 828） cGy·cm^2, （1 335 ± 717） mGy, respectively, radiation dose of embolisation group was evidently higher than that of angiography group. In 4.6 % of instances, which were cerebral embolisation, CD was greater than 2 Gy. These data showed that radiation protection for these patients must be enhanced.
