The device is logically called Second Look®, and it received approval from the U.S. Food and Drug Administration Feb. 1. It's made by CADx, a Canadian firm, a subsidiary of a British company. Second Look is a computer-aided detection system that is used in screening mammograms and diagnosing some results that might need additional examination.
The new system looks at existing mammograms through a device called a Mammagraph®. This device enhances the mammogram imaging and may detect cysts and lumps initially missed.Some researchers have estimated as much as 20 percent of breast cancer tumors may be missed by a mammogram alone.
More than 200,000 breast cancer cases are reported in the United States each year. Early detection is a key to survival and to treatment options.
This information from the Hospital Management.net -- an organization that follows developments in hospital operations -- gives an evaluation of the Second Look® system.
And this section of the CADx site describes how the device works.
