The aim of this study was to determine ovarian dose, effective dose and associated radiogenic risks from hysterosalpingography (HSG), and to provide data for the estimation of radiogenic risks related to HSG studies performed in any laboratory. The fluoroscopy time, number of radiographs taken and entrance surface dose were measured in a series of 78 consecutive patients undergoing HSG as part of their infertility work-up. Organ-dose values per radiograph and per minute of fluoroscopy were separately determined using an anthropomorphic phantom and thermoluminescence dosimetry. The radiogenic risk for deleterious effects on a possible future embryo and the radiogenic risk for cancer induction on the patient undergoing HSG were estimated. The average HSG procedure in our laboratory involves a mean fluoroscopic time of 0.3 min and a mean number of radiographs of 3.2. The dose to female gonads from an average HSG procedure was 2.7 mGy and the patient effective dose was 1.2 mSv. The risk for radiogenic anomalies in a future embryo of the woman undergoing an average HSG procedure and the risk for radiogenic fatal cancer induction in the exposed woman were estimated to be less than 10(-3) of the correspondent nominal risks. Radiation risks from a typical HSG are low, but they may be elevated if fluoroscopic and/or radiographic exposures are prolonged for any reason. Present data allow the estimation of radiogenic risks associated with HSG procedures performed in other laboratories with use of different equipment, screening time and number of radiographs taken.
本研究的目的是确定子宫输卵管造影术（HSG）的卵巢剂量、有效剂量及相关辐射风险，并为估算在任何实验室进行的HSG研究相关辐射风险提供数据。在一系列78例连续接受HSG检查以评估不孕情况的患者中，测量了透视时间、拍摄的X光片数量和体表入射剂量。使用人体模型和热释光剂量测定法分别确定每张X光片和每分钟透视的器官剂量值。估算了对未来可能胚胎产生有害影响的辐射风险以及接受HSG检查患者的致癌辐射风险。我们实验室的平均HSG检查程序包括平均0.3分钟的透视时间和平均3.2张X光片。平均HSG检查程序对女性性腺的剂量为2.7毫戈瑞，患者有效剂量为1.2毫希沃特。接受平均HSG检查程序的女性未来胚胎发生辐射性异常的风险以及受照女性发生辐射性致命癌症的风险估计低于相应标称风险的10^(-3)。典型HSG的辐射风险较低，但如果因任何原因延长透视和/或X光照射时间，风险可能会升高。现有数据可用于估算在其他实验室使用不同设备、筛查时间和拍摄X光片数量进行HSG检查程序时的辐射风险。
