Although radionuclide hysterosalpingography (RNHSG) has been suggested as an efficient procedure for assessing function of fallopian tubes, the radiation dose to the ovaries was addressed as an important issue to be taken into consideration. We describe a modified method of RNHSG, calculating the radiation dose to the ovaries. A small dose of approximately 18.5 MBq (0.5 mCi) of [99mTc]pertechnetate was administered directly into the uterine cavity without overpressure. The accuracy of the method was 84.5% as compared with the contrast hysterosalpingography. The estimated average dose to the ovaries was 0.057 mGy/MBq (0.21 rad/mCi) or 1.08 mGy (108 mrad) per study. RNHSG is an accurate method for functional study of fallopian tube patency with low radiation dose.
尽管放射性核素子宫输卵管造影术（RNHSG）已被认为是评估输卵管功能的有效方法，但卵巢所接受的辐射剂量仍是一个需要考虑的重要问题。我们描述了一种改良的RNHSG方法，并计算了卵巢所接受的辐射剂量。将小剂量约18.5 MBq（0.5 mCi）的高锝[99mTc]酸盐直接注入子宫腔，且不过压。与子宫输卵管造影对比，该方法的准确率为84.5%。每次检查时，卵巢所接受的估计平均剂量为0.057 mGy/MBq（0.21 rad/mCi）或1.08 mGy（108 mrad）。RNHSG是一种用于输卵管通畅性功能研究的准确方法，且辐射剂量低。
