Digital Mammography with CAD (Computer Aided Detection), just like
traditional film mammography, is used by radiologists to screen for and
diagnose breast cancer. For the patient, the procedures are the same: in
both cases, X-rays of compressed breast tissue create an image of the
inside of the breast. For the physician, however, the results of a
digital mammogram offer the following benefits that are not always
afforded by film mammography:
- Speed: Digital mammograms appear on a
high-resolution monitor in mere seconds. Technicians and physicians
don’t have to wait for film to develop.
- Detail: Because the digital mammogram can be
enhanced or refined, magnified and manipulated by the radiologist
through the use of a computer, even small differences between normal and
abnormal breast tissue are seen more easily than they would be on film.
- Less Radiation over Time: Thanks to the detailed
nature of digital mammography, fewer follow-up procedures are necessary
than with film mammography. This can result in less exposure of
radiation to the patient over time.
- Storage and Sharing: Stored digitally, mammogram
files do not take up physical office space. Additionally, they can
easily be shared between health care providers when coordinating care.
Recommended guidelines for both digital and film mammography are the
same. The American Cancer Society, the American College of Radiology,
and the American Medical Association recommend a baseline mammogram at
or before age 40, and a screening mammogram every year after age 40.
Not everyone needs or should have digital mammography. Some cases are
better suited to film mammography. Your physician will suggest the best
course of action based on the details of your case.
