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.
作为不孕症调查的一部分，对两组各32例患者进行了使用数字和传统影像增强技术的子宫输卵管造影。辐射剂量记录为表面剂量。在51.7%的数字图像和54.8%的传统图像中，检查结果正常。传统技术的表面剂量为442±144 cGy/cm²，显著高于数字影像增强技术的207±113 cGy/cm²。使用传统技术时的曝光次数也显著更多。与传统的100毫米胶片相比，数字图像在诊断细节上并无欠缺。
