Dear AuntMinnie Member,
Computer-aided detection (CAD) isn't just for breast imaging anymore. Two stories we're highlighting this week point to increased CAD usage across a variety of modalities and applications, from conventional radiography to virtual colonoscopy.
Dear AuntMinnie Member,
Computer-aided detection (CAD) isn't just for breast imaging anymore. Two stories we're highlighting this week point to increased CAD usage across a variety of modalities and applications, from conventional radiography to virtual colonoscopy.
In our first article, Austrian researchers explain a CAD application they've developed to detect signs of rheumatoid arthritis. The group's goal was to speed up the review of radiography studies of metacarpal bone defects while maintaining a high level of accuracy, according to staff writer Eric Barnes.
The CAD software analyzes digitized radiography images and compares them to a database of normal subjects. Although the study sample was small and the research remains preliminary, the algorithm worked quickly and had a low error rate.
In our second story, University of Chicago researchers led by virtual colonoscopy pioneer Dr. Abraham Dachman discussed their results applying CAD technology to that emerging technique. As reported by contributing writer Jerry Ingram, Dachman and colleagues found that CAD increased the performance of radiologists and a gastroenterologist participating in the study. You might be surprised at who benefited the most from computer assistance.
In another study in the same article, Dr. Ronald Summers and colleagues from the National Institutes of Health in Bethesda, MD, found that contrast enhancement improved their CAD's performance slightly.
You'll find all of these studies in our Advanced Visualization TrendWatch special section, your home on AuntMinnie for articles on cutting-edge image visualization topics.
