March 6, 2009 - Medicsight PLC launched ColonCAD API 4.0, the latest version of its computer-aided detection software, today at ECR 2009 in Vienna. The software is designed to assist radiologists in the detection of colorectal polyps in CT colonography image data. Version 4.0 includes a significant increase in the performance of the polyp detection algorithm, reducing the number of false positive CAD marks displayed for each patient case. David Burling, M.D., Consultant Gastrointestinal Radiologist and VC Program Director at St. Mark's Hospital, London, UK, said, "We welcome this latest improvement to Medicsight's ColonCAD product. CAD is now an integral part of our reading strategy in routine clinical practice. It improves interpretation accuracy and is complimentary to workflow." Internal testing on a dataset of 91 patient cases showed that the ColonCAD API 4.0 maintains the same high levels of sensitivity to the previous version but displays a 50 percent reduction in false positives, with the CAD now returning a mean of 6.5 false positive marks per patient case, according to data Medisights’ data on file. ColonCAD API 4.0 has been CE Marked and will be available for sale in Europe through Medicsight's network of partners. For more information: www.mgtci.com

A new artificial-intelligence-based approach to image reconstruction, called AUTOMAP, yields higher quality images from less data, reducing radiation doses for CT and PET and shortening scan times for MRI. Shown here are MR images reconstructed from the same data with conventional approaches, at left, and AUTOMAP, at right. Athinoula A.
