A technology called monochromatic X-ray imaging could reduce radiation dose per mammogram by a factor of five to 10 times, according to a research review published in the European Journal of Radiology. However, the radiation delivered by the technique has been a focus of debates regarding possible cancer risk associated with breast screening.
