Mean glandular dose
Amount of radiation absorbed by a breast during mammography
In mammography, mean glandular dose (MGD) is a quantity used to describe the absorbed dose of radiation to the breast. It is based on a measurement of air kerma and conversion factors. MGD can be calculated from measurements made with poly(methyl methacrylate) (PMMA) blocks. It is often used to compare typical doses to patients between different centres or internationally, and is the preferred measure of the potential risk from mammography.[1][2][3]
