Dear Advanced Visualization Insider,

Computer-aided detection (CAD) technology has been explored for a number of applications, including breast imaging, virtual colonoscopy, and the evaluation of lung nodules. But its use to date in musculoskeletal applications has been limited.

Up to now, that is. A team of researchers from the University of Maryland School of Medicine recently evaluated a homegrown CAD application with knee MR images. The researchers found that their algorithm performed comparably to radiologists working without CAD support in detecting meniscal tears, but didn't fare quite as well in evaluating articular injuries.

Dr. Nabile Safdar presented the findings at last week's Society for Imaging Informatics in Medicine (SIIM) meeting, and our coverage of his talk is the subject of this month's Insider Exclusive article. You have access to the story before it is published for the rest of our AuntMinnie.com members. To learn more about the potential of CAD with knee MR studies, click here.

In other articles we're featuring from SIIM 2008, hear about why some experts believe that 3D has become a necessary service expected from radiologists by surgeons and other clinicians. Contributing writer Cynthia Keen has that story here.

In addition, the society's Transforming the Radiology Interpretation Process (TRIP) conducted a study of compression techniques, and found that lossy compression of thin-slice multidetector-row CT (MDCT) images was perceptible at even low ratios. Stay tuned for further coverage of the SIIM meeting in the coming weeks.

Also this month in the Advanced Visualization Digital Community, virtual colonoscopy CAD was found to detect polyps in either prepped or unprepped patients. You can find that article by staff writer Eric Barnes here.

We've recently given the community a new look, and we'd love to know what you think. Feel free to send your feedback to me at the address below.
