Q How is digital mammography different from conventional mammography?
A Both digital and film mammography use low-dose x-rays to produce an image of the breast.
Conventional mammography uses x-ray film. The film is developed, and reviewed by a radiologist.
Digital mammography takes an electronic image of the breast and stores it directly in a computer. The technologist will not have to wait to develop film, and will know immediately if the images are satisfactory, so the exam time can be reduced by 15-20 minutes. Recent research suggests that digital mammography is more accurate in women under 50 or women with dense breasts. Digital mammography also facilitates computer-assisted detection. In addition to the review of the images by the radiologist, computer software also searches for any potential abnormalities.
