The number of breast imaging facilities equipped with digital mammography (also called computed radiography mammogram (CRM), CR mammogram) is growing due to a number of advantages. Digital images can be stored directly in a picture archiving and communication system (PACS) and allows the printing, enhancement, magnification, or brightness and contrast manipulation for further evaluation. The sensitivity of digital mammography compared to film mammography is better in women with dense breasts, a population at higher risk for breast cancer, due to these post processing possibilities. 'The American College of Radiology's (ACR) Imaging Network found that digital mammography detected up to 28 percent more cancers than film-screen mammography in women age 50 and younger, premenopausal and perimenopausal women, and women with dense breasts, as reported in October 2005 in the New England Journal of Medicine.' Advantages of digital mammography:
•
Faster image acquisition;
•
shorter examination time;
•
improved contrast between dense and non-dense breast tissue;
•
under or over x-ray exposure can be corrected without repeated mammograms;
•
post processing of breast images for more accurate detection of breast cancer;
•
Easy storage and transmission over phone lines or a network.
Existing mammography equipment can be converted to 'digital' operation, which allows cost savings compared to integrated digital mammography systems. See also Breast MRI. • View NEWS results for 'Digital Mammography' (2). Further Reading: Basics:

This term usually refers to the storage of patient data and images.
Images are best archived in digital form (e.g., on optical disks, DVDs, PACS systems) and not only on films (hard copies, prints). Data compression via a reduction in matrix size, pixel depth or CT numbers, will result in a loss of spatial and contrast resolution. Digital images should be converted into a universal format such as DICOM. Raw data saving is necessary when additional image reconstructions are required.
