Medicsight PLC Presents New Data at RSNA 2008 Further Supporting Relevance of Computer-Aided Detection (CAD) and Image Analysis Software in Early Colon Cancer Screening and...( Chicago Dec. 3 /- Medicsight PLC an i...),Health

Chicago, Dec. 3 /PRNewswire/ -- Medicsight PLC, an industry leader in and principal developer of Computer-Aided Detection (CAD) and medical image analysis software today announced clinical results from a new study that demonstrated CAD significantly increased the sensitivity of readers in the detection of colorectal cancers in multi-row detector CT (MDCT) colonography (CTC). The results also demonstrate that when both expert and non-expert CTC readers used CAD, it increased their sensitivity in detecting and diagnosing colorectal cancers. Medicsight presented data from this study and from additional abstracts that demonstrate the clinical relevance of CAD in early detection and diagnosis of colon cancer at the 94th Scientific Assembly and Annual Meeting of the Radiological Society of North America (RSNA) being held through December 5, 2008 in Chicago, IL, USA.

The study (Abstract # SSM10-06: Colorectal Cancers: Effect of Computer-aided Detection in Multirow Detector CT-Colonography - [December 3, 3:50 PM CST]), conducted in Beijing, China, included 60 patients previously diagnosed with colorectal cancers. The patient data was retrospectively reviewed, first without CAD and then with CAD, by four radiologists (two expert and two non-expert radiologists) blinded to colonography and pathology findings. Results showed that CAD increased the sensitivity of expert readers from 80% to 93% (P=0.01) and 97% (P=0.007), and the sensitivity of non-expert readers from 73% and 67% to 90% (P=0.008, P=0.001), respectively.

Medicsight has recently submitted its application for 510(k) clearance to the U.S. Food and Drug Administration (FDA) for its product, ColonCAD(TM), an advanced CAD algorithm used to analyze CT scans of the colon and automatically highlight suspicious areas that may be indicators of disease.
