Dear AuntMinnie Member,
A study on computer-aided detection (CAD) that we're highlighting today in our Advanced Visualization Digital Community adds weight to the body of evidence accumulating in support of CAD's value in mammography screening.
Norwegian researchers used CAD to analyze baseline mammograms from a study group of nearly 24,000 women. The screening program had already performed double reading by two radiologists, and CAD was applied to mammograms that had cancers missed by one or both readers.
The researchers found that if CAD had been part of the original screening protocol, and CAD marks were correctly acted upon, the cancer detection rate would have increased for film-screen as well as full-field digital mammography, both of which were used in the screening program.

Delayed CT for trauma
In news from our CT Digital Community, Italian researchers found that whole-body CT of trauma patients could detect additional signs of injury if the protocol included an additional scan five minutes after contrast administration. But delayed scanning was only worth the extra time and radiation dose some of the time. Learn more by clicking here, or visit the CT Digital Community at ct.auntminnie.com.
CMS and cardiac MRI flow studies
Last but not least comes word that the U.S. Centers for Medicaid and Medicare Services (CMS) has initiated a new national coverage analysis regarding flow studies performed with cardiac MRI. A coalition of imaging organizations had asked for the opportunity to present evidence on the usefulness of such studies.
