Questions over use of computer aid for mammograms

New questions are being raised about the effectiveness of a high tech aid for mammograms.

Computer-Assisted Detection, or CAD, works almost like a spell check. It looks for potential abnormalities on a mammogram that a radiologist might otherwise miss.

A study in the Journal of the National Cancer Institute analyzed detection rates of facilities that did and didn't use CAD.

Authors report use of the computer increased false positive results and did not improve the detection of real abnormalities.

Researchers say it's possible some radiologists don't use CAD to its full effect.
