    Area of Science:

    • Medical Imaging
    • Radiological Physics
    • Oncology

    Context:

    • Xeromammography is a medical imaging technique used for breast cancer screening.
    • Conventional xeroradiography and foilless film methods have associated radiation doses.
    • Optimizing radiation dose is crucial in mammography to minimize potential risks.

    Purpose:

    • To evaluate the effectiveness of a 3 mm aluminum filter in reducing radiation dose during xeromammography using the Senographe system.
    • To compare the radiation dose and diagnostic quality of the filtered system with conventional xeroradiography and foilless film mammography.

    Summary:

    • Implementing a 3 mm aluminum filter in xeromammography with the Senographe system substantially reduces radiation exposure.
    • Radiation dose is decreased by a factor of 2-3 compared to conventional xeroradiography and 10-12 compared to foilless film.
    • The applied tissue dose ranges from 0.14 to 0.30 rad per exposure, lowering the hypothetical radiogenic cancer risk.

    Impact:

    • This technique lowers the radiation dose in mammography, potentially reducing the risk of radiation-induced carcinoma.
    • The use of the aluminum filter does not compromise the quality of the radiographs or the diagnostic validity of the mammograms.
    • Offers a safer mammography screening option by significantly reducing patient radiation exposure while maintaining diagnostic accuracy.
