Explain mammography procedure to patient (*e.g., positioning, compression). Compression helps to spread out the normal fibroglandular (dense) tissue of the breast making it easier for radiologists to see through the breast tissue and detect abnormalities that might be hidden by the overlying tissue. A link to download the new manual at no charge was emailed to the facility and technologist contacts (the persons with the ACR Mammography Accreditation login information) at all ACR-accredited mammography facilities on November 19, 2018, with instructions to share the link with their colleagues at the facilities, including their medical physicists. As a suggested mammographic guideline, compression pressures of approximately 10kPa aid in image acquisition reproducibility both within and between women; pain levels decrease, with minimal variations to breast thickness, AGD and image quality. The compression test was undertaken to check that the mammography system provides an adequate compression in manual and automatic mode, to check the accuracy (or deviation) of the indicator of the compression force which is present on the equipment and to check the accuracy of the compression thickness indicator. Questions like these inspired Hologic researchers and scientists to develop Hologic 3D.
