Digital strategies aim to reduce breast imaging radiation dose

April 1, 2008 Diagnostic Imaging. Digital strategies aim to reduce breast imaging radiation dose WOMEN'S HEALTH Karen Sandrick -------------------------------------------------------------------------------- Because modern digital detectors can be tuned to be more efficient than screen-film systems, they automatically lower the radiation dose to the patient while maintaining the image quality radiologists crave. Photon-counting, the method used in Sectra's detector, for example, minimizes patient exposure to radiation. In a 2006 analysis, the British National Health Service Breast Screening Programme reported that the Sectra MicroDose Mammography system achieved significant dose savings over screen-film mammography. The average mean glandular dose of the MicroDose System in this analysis was 0.57 mGy, 75% lower than average dose levels in film imaging systems.
