Mob rule: VC results from 'crowdsourcing' competitive with CAD
Can computer workers without medical training distinguish true polyps from false ones as effectively as virtual colonoscopy computer-aided detection (CAD) software? Actually, they do almost as well as CAD -- and sometimes better -- according to a study of Web-based "crowdsourcing" applied to polyp classification.

JACC: Questions remain about cardiac radiation's link to cancer
There are still no strong data linking the use of ionizing radiation in cardiac imaging to the development of cancer, though several studies have found that higher radiation exposure may increase the risk of developing cancer, concludes a paper published online January 30 in the Journal of the American College of Cardiology.

Follow-up protocol performs well in CT lung screening
Researchers reported good results with a protocol for working up patients with nodules found on CT lung screening, according to research in the February American Journal of Roentgenology. The algorithm produced low false-positive rates, and could make the establishment of large-scale CT screening programs more feasible.
