To determine the proportion of radiation exposure from fluoroscopy during the performance of hysterosalpingography, using a digital image intensifier.
20 women with primary or secondary sterility were examined. The total radiation dose was measured and the proportion due to fluoroscopy was determined. The use of a computer programme permitted accurate differentiation of the dose obtained by fluoroscopy and radiography. Total mean radiation dose was 256 cGy x cm2; fluoroscopy contributed 187 cGy x cm2. On average, fluoroscopy contributed 69% of total radiation dose.
During hysterosalpingography with a digital image intensifier, fluoroscopy should be as brief as possible since it contributes most of the radiation dose.
使用数字影像增强器确定子宫输卵管造影术过程中透视检查所产生的辐射暴露比例。
对20例原发性或继发性不孕症女性进行检查。测量总辐射剂量并确定透视检查所致的比例。使用计算机程序可准确区分透视检查和放射摄影所获得的剂量。总平均辐射剂量为256 cGy×cm²；透视检查贡献了187 cGy×cm²。平均而言，透视检查占总辐射剂量的69%。
在使用数字影像增强器进行子宫输卵管造影术时，透视检查应尽可能简短，因为它贡献了大部分辐射剂量。
