进行了一项调查，以估计接受乳腺X线摄影的女性的平均腺体剂量（MGD），并报告剂量分布、压缩乳房厚度、腺体组织含量和所用的乳腺X线摄影技术因素。从6,006名妇女的24,471张乳房X线照片中收集了临床数据。调查数据包括使用钼（Mo）阳极和Mo或铑（Rh）过滤器的七个现代单位的乳房X线照片。每次乳房X线照片的曝光系数自动记录在每个装置的软盘上。所有乳房X线摄影装置均使用不同腺体含量的乳腺组织等效衰减片单独校准，因此可以根据曝光因子和压缩乳房厚度估计乳腺腺体含量。根据标准化腺体剂量和计算的空气中入口暴露量，估计每次乳房X线摄影的MGD。调查发现MGD中位数为2.6 mGy。乳房腺体组织含量中位数为28%，乳房受压厚度中位数为5.1 cm。此外，将患者衰减数据转换为等效BR-12和丙烯酸厚度，以帮助确定乳腺X射线摄影装置自动曝光控制性能评估所需的适当体模厚度。
A survey was conducted to estimate the mean glandular dose (MGD) for women undergoing mammography and to report the distribution of doses, compressed breast thickness, glandular tissue content, and mammographic technique factors used. From 24,471 mammograms, of 6,006 women, clinical data were collected. The survey data included mammograms from seven modern units using a molybdenum (Mo) anode and either Mo or rhodium (Rh) filter. Exposure factors for each mammogram were recorded automatically onto a floppy disk on each unit. All mammography units were calibrated individually using breast tissue equivalent attenuation slabs of varying glandular content, so the breast glandular content could be estimated on the basis of exposure factors and compressed breast thickness. The MGD was estimated for each mammogram based on the normalized glandular dose and calculated entrance exposure in air. The survey found a median MGD of 2.6 mGy. The median breast glandular tissue content was 28% and the median compressed breast thickness was 5.1 cm. Also, patient attenuation data were converted to equivalent BR-12 and acrylic thickness to help determine appropriate phantom thicknesses required for mammography unit automatic exposure control performance assessment.
