Bellevue-based Confirma, a maker of MRI imaging analysis products, has been acquired by Merge Healthcare in a stock deal valued at $22 million.

Confirma's CADstream product -- with 1,200 systems implemented at facilities throughout the world -- provides more detailed analysis and reporting for MRI studies related to breast and prostate cancers.

Last year, Confirma scored $17.5 million in venture financing from Telegraph Hill Partners, Fluke Venture Partners, Northwest Venture Associates, Prism Ventureworks and Versant Ventures. The company -- which has partnerships with McKesson, GE Healthcare and Philips Medical -- is led by Wayne Wager, a former venture capitalist at Encompass Ventures.

“By combining our patented CAD applications with Merge’s broader health IT solutions and global presence, we can better take advantage of current and future growth opportunities and, thus, extend our solutions to more clinicians,” Wager said in a release.
