A new study published in the December 2006 issue of Gastroenterology that investigated the effect of CAD on readers' interpretation of CT colonography showed that Medicsight CAD (computer-aided detection) significantly improved reader interpretation of CT colonography.
The study, performed by Professor Steve Halligan and colleagues from University College Hospital London and the Centre for Statistics in Medicine, Oxford, UK, tested the effect of CAD assistance on the performance of 10 readers who were 'non-expert' in the interpretation of CT colonography. Each participant read 107 CT colonography cases: 60 patients had 142 polyps and the remaining 47 had normal colons. The cases were first read without the assistance of CAD and then two months later the studies were read with the assistance of CAD, using Medicsight ColonCAR. The results found that readers detected significantly more polyps with CAD than without, and that with CAD 41, or 68 percent, of the 60 patients with polyps were more likely to be detected by readers.
