The latest version of CT colonography software from Medicsight debuted this week at ECR 2009. The newly enhanced software, dubbed ColonCAD API 4.0, uses a more powerful algorithm to uncover colorectal polyps in CT data. The CE-Marked product, which will be sold through the company’s European distributors, offers increased specificity that cuts the number of false positive CAD marks per case.
Internal tests involving patient cases demonstrated that the ColonCAD API 4.0 remains as sensitive as the previous version, but displays 50% fewer false positive marks. This works out to a mean of 6.5 false marks per patient case, according to the company. Sensitivity is 85% for polyps 2mm to 50 mm; 90% for polyps 6mm to 9 mm; and 92% for polyps 10mm and larger.
