CDI Acquires Stake in EPIC Imaging


Center for Diagnostic Imaging has entered into a partnership with EPIC Imaging to operate its four imaging centers in greater Portland, Oregon.

The agreement bolsters CDI’s presence in the Northwest, which includes centers in Northern California and Seattle. CDI, which merged with Insight Imaging in 2012, is the nation’s second-largest diagnostic imaging center chain. It operated 100 imaging centers in 2015, about evenly divided between wholly owned centers and joint ventures.

The fifteen radiologists who own EPIC Imaging will continue to provide interpretations. With the exception of one interventional radiologist who performs IR procedures at two local hospitals, the practice is 100% outpatient-imaging based.

“EPIC Imaging is a natural fit for CDI,” said Rick Long, CDI president and CEO, in a prepared statement. “We share a long history and commitment to quality, value, access, and service excellence. And we’re thrilled to have them part of our network while maintaining the same great center staff and strong local clinical teams, including their subspecialized radiologists that are so well-known and respected in the community.”

EPIC was founded more than 50 years ago by radiologist Gerald Warnock, MD. Warnock sold majority interest in the practice and imaging center assets to the then-employed radiologists in 2009 and will retire at the end of this year. The practice was an early adopter of PACS in 2000 and its imaging centers and radiologists enjoy an excellent reputation for clinical quality in the Portland medical community. Warnock continues to be listed as chair emeritus on the EPIC website.

“Partnering with CDI allows us to extend and expand the breadth of our high-quality diagnostic imaging services and procedures in Portland,” said John Griffith, former CIO and operations director for EPIC, now CDI VP operations and business development for the Portland centers. “By tapping into CDI’s robust operational platforms and best practice sharing, our patients and the medical providers locally will have even greater access to state-of-the-art, industry-leading care and services.”

EPIC Imaging made news in 2005 when Warnock sued the dominant local hospital provider Providence Health Systems in federal court seeking an injunction against the termination of a preferred provider contract with the outpatient imaging provider.  The judge in that case ruled against the plaintiffs, saying that they failed to raise a question about the probability of monopoly power.
