Patient dosimetry in hysterosalpingography: a comparative study

Ovarian doses for 45 women undergoing hysterosalpingography (HSG) at our institution were calculated. Lithium borate thermoluminescent dosemeters were used to measure entrance surface doses in standard positions. The study compares the estimated dose received by 21 patients undergoing the procedure using an analogue fluoroscopic unit and standard film-screen radiography with that received by 24 patients who were imaged using a digital screening system with a C-arm. Our results show significant dose reduction is obtainable for patients undergoing HSG when a digital system is employed.
