Abstract: | 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. |
