text: [Radiation dosage during hysterosalpingography using a digital image intensifying technique].
  Hysterosalpingography using a digital and conventional image intensification technique was carried out on two groups of 32 patients as part of investigation for infertility. Radiation dose was recorded as surface dose. In 51.7% of digital images and 54.8% of conventional images the findings were normal. Surface dose with conventional technique was 442 +/- 144 cGy/cm2, significantly higher than 207 +/- 113 cGy/cm2 with digital image intensification. The number of exposures was also significantly higher when using the conventional technique. The digital images showed no lack of diagnostic detail when compared with the conventional 100 mm films.
