An educational session at the Radiology Society of North America's annual conference, Nov. 27-Dec. 2 in Chicago, will explore new trends in computer-assisted decision support systems for breast cancer care.

These systems, called CAD, currently are used to analyze digital mammograms and detect suspicious areas that could be abnormalities. Newer technologies--computer-assisted diagnostics--are appearing that go beyond simple detection, says Maryellen Giger, PhD, a professor of radiology at the University of Chicago.

Some detection systems can give clinicians the size of a lesion and some descriptive features. Computer-assisted diagnostic systems under development may further characterize the lesion, and with quantitative image analysis could potentially aid in assessing prognosis or response to therapy, Giger says.

Giger, co-presenting the three-part session, will review current and developing CAD technologies, and encourage robust validation and subsequent adoption. Other parts of the session cover computer-aided detection, and clinical aspects of computer-assisted detection and diagnosis systems.

Course No. RC421, "New Trends in Breast CAD," is scheduled at 4:30 p.m. on Tuesday, Nov. 29, in Room E352 at McCormick Place. More information is available at
