title: [Radiation exposure during digital hysterosalpingography: how much is due to fluoroscopy?].
abstract: OBJECTIVE
  To determine the proportion of radiation exposure from fluoroscopy during the performance of hysterosalpingography, using a digital image intensifier.
  
  
  METHODS
  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.
  
  
  CONCLUSIONS
  During hysterosalpingography with a digital image intensifier, fluoroscopy should be as brief as possible since it contributes most of the radiation dose.
