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.

D011829	Radiation Dosage	The amount of radiation energy that is deposited in a unit mass of material, such as tissues of plants or animal. In RADIOTHERAPY, radiation dosage is expressed in gray units (Gy). In RADIOLOGIC HEALTH, the dosage is expressed by the product of absorbed dose (Gy) and quality factor (a function of linear energy transfer), and is called radiation dose equivalent in sievert units (Sv).

D011856	Radiographic Image Enhancement	Improvement in the quality of an x-ray image by use of an intensifying screen, tube, or filter and by optimum exposure techniques.
