神经血管介入放射学(NERO-IR)过程往往需要较长的透视曝光时间和重复的数字减影血管造影术。在神经IR内科医生中，评估使用直接眼剂量计测量眼晶状体剂量的实际情况是很重要的。86例患者接受了DOSIRIS(TM)(IRSN，法国)[3 mm剂量当量，HP(3)]的直接剂量测量。此外，颈部个人剂量计(玻璃徽章)[0.07 mm剂量当量，HP(0.07)]被佩戴在颈部左侧防护围裙外。放射防护眼镜外、内平均每例受照剂量分别为0.04mSv/例和0.02mSv/例。防辐射玻璃的防护效果约为60%。医生眼镜片的剂量往往被颈玻璃徽章测量高估了。神经IR内科医生需要使用DOSIRIS(TM)等眼部剂量计正确评估晶状体剂量[HP(3)]。
Neurovascular interventional radiology (neuro-IR) procedures tend to require an extended fluoroscopic exposure time and repeated digital subtraction angiography. To evaluate the actual measurement of eye lens dose using a direct eye dosemeter in neuro-IR physicians is important. Direct dosimetry using the DOSIRIS (TM) (IRSN, France) [3 mm dose equivalent, Hp(3)] was performed on 86 cases. Additionally, a neck personal dosemeter (glass badge) [0.07mm dose equivalent, Hp(0.07)] was worn outside the protective apron to the left of the neck. The average doses per case of neuro-IR physicians were 0.04 mSv/case and 0.02 mSv/case, outside and inside the radiation protection glasses, respectively. The protective effect of radiation protection glasses was approximately 60%. The physician eye lens dose tended to be overestimated by the neck glass badge measurements. A correct evaluation of the lens dose [Hp(3)] using an eye dosemeter such as DOSIRIS (TM) is needed for neuro-IR physicians.
