Medicsight unveils new version of ColonCAD at ECR 2009

Friday 6th March 2009

Medicsight PLC, industry leader in the development of Computer-Aided Detection (CAD) and image analysis software which assists in the early detection and diagnosis of disease, is pleased to announce it has launched ColonCAD API 4.0, the latest version of its computer-aided detection software, today at the European Congress of Radiology (ECR 2009) show 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. 

Dr David Burling, Consultant Gastrointestinal Radiologist and VC Program Director at St Mark's Hospital, London, UK commented today: "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% reduction in false positives, with the CAD now returning a mean of 6.5 false positive marks per patient case.

ColonCAD API 4.0 demonstrates the following sensitivity:

Size of Polyp                          Sensitivity
2mm-50mm                            85%
6mm-9mm                              90%
10mm+ (clinically significant)    92%+

The patient data used in this testing remained independent from the development of the CAD and have been endoscopically validated and reviewed by a panel of expert radiologists to determine the ground truth against which the CAD performance was assessed.

Allan Rowley, Chief Executive of Medicsight, commented: "Previous research has shown Medicsight's ColonCAD significantly improves the performance of radiologists in the detection of polyps in CT colonography image data.  The reduction in the numbers of false positives returned by our latest version of CAD is expected to further improve the performance of radiologists, by reducing the number of CAD marks which must be assessed when reviewing a patient dataset."

ColonCAD API 4.0 has been CE Marked and will be available for sale in Europe through Medicsight's network of partners.
More than 17,000 medical and industry professionals from over 95 countries will be attending this year's ECR which is taking place in the Austria Center, Vienna from 6-10 March.

Visitors will be able to see demonstrations of the Medicsight ColonCAD software integrated into their partners' 3D advanced visualisation workstations at the company's exhibition booth no 506 in Expo E.
