What is Digital Mammography with CAD?

One of the most recent advances in x-ray mammography is digital mammography. Digital (computerized) mammography is similar to standard mammography in that x-rays are used to produce detailed images of the breast. From the patient's perspective, a digital mammogram is the same as a standard film-based mammogram in that breast compression and radiation are necessary to create a clear image of the breast. However, conventional film mammography requires several minutes to develop the film while digital mammography provides the images on the computer monitor in less than a minute. Thus, digital mammography provides a shorter exam time.

Digital Mammography has benefits which include:

  • Improved contrast between dense and non-dense breast tissue
  • Faster image acquisition
  • Shorter exam time
  • Easier film storage
  • Physician manipulation of breast images for more accurate detection of breast cancer

A significant breakthrough in mammography, Selenia Full Field Digital Mammography system provides higher image clarity and quality and the largest detector available today. It requires fewer exposures and provides faster imaging and less discomfort for women.

What is CAD?

Computer-Aided Detection (CAD) is used by radiologists as "a second pair of eyes" when reading mammograms. Radiologists review a mammogram then activate the CAD software and re-evaluate the marked area(s) before issuing a final report. This software identifies features on medical images and brings them to the attention of the radiologist. It does not replace the imaging technology; rather it is an interpretive aid to be used during image review.
