Digital Mammograms at University of Colorado Hospital
The Breast Center at University of Colorado Hospital uses two state-of-the-art digital imaging machines to perform mammograms. UCH implemented this digital process in Fall 2008 to improve diagnostic accuracy as well as your satisfaction as a patient.

A large-scale study of digital imaging for mammograms supports the benefits of the new system. Results from the The Digital Mammographic Imaging Screening Trial, a study of nearly 50,000 women, showed that digital mammograms were 15 percent to 28 percent more effective than film mammograms at detecting breast cancer in young women, women with dense breasts, and in pre-menopausal women.
Radiologists can adjust the brightness and contrast of digital images, which improves their ability to interpret the mammogram. This is a capability they did not have with film.
The digital equipment also offers a "computer-aided detection" (CAD) feature. A CAD mammogram includes marks that tell radiologists to check areas that the computer thinks could indicate cancer.
The Breast Center at UCH is also using CAD for breast magnetic resonance imaging (MRI), which produces 3,000 to 3,500 images for each patient, which aids in MRI-guided breast biopsies.
Improved efficiency, more comfort
Digital imaging improves efficiency because it eliminates the time needed to process filmed images. Once taken, a digital image appears immediately on the computer screen, and the patient can quickly be repositioned if necessary. Patients no longer have to go to the waiting room while a technologist checks the suitability or clarity of a film image.
The new equipment includes tungsten x-ray tubes, which lessen considerably the radiation dose a patient receives. University of Colorado Hospital is the first in the state to use this new technology. (Tyler Smith, managing editor, UCH Insider)
3-D mammograms available to patients
At the end of May 2012, University of Colorado Hospital made its new 3-D mammogram machine available to patients.
The machine was purchased with proceeds from the UCH Foundation's Men for the Cure event.
