Rhode Island Medical Imaging and its 90 physicians have agreed to join independent practice coalition Strategic Radiology, the two announced Wednesday.

Around for over 80 years, RIMI has a network of 16 private diagnostic imaging facilities overseen by its staff of subspecialized radiologists. The practice also performs procedures and interprets images for 10 Rhode Island hospitals and one more in Massachusetts.

Practice President John Pezzullo, MD, said Rhode Island Medical Imaging made the decision to help preserve its autonomy.

“RIMI is proud to join the Strategic Radiology community and is committed to continuing as a physician owned and operated independent practice,” Pezzullo, an associate professor of diagnostic imaging at Brown University, said in a statement. “In becoming part of this esteemed organization, we not only expect to strengthen our independent practice model by taking advantage of SR’s operational efficiencies, but also contribute to the future success of the organization by sharing best practices.”

Rhode Island Medical Imaging is currently developing a peer learning program and maintains a “sophisticated” quality infrastructure, Strategic Radiology noted. The American College of Radiology has recognized its outpatient offices as Centers of Excellence, and the ACR and Joint Commission have accredited the academic and community hospital radiology departments RIMI serves.

“RIMI’s commitment to quality patient care, independent practice, and the future of the specialty are private practice hallmarks shared by all Strategic Radiology members,” Scott Bundy, MD, chair and CEO of Strategic Radiology, said in the same statement.

The practice reached its considerable size, in part, through acquisition, adding Radiology Associates and its three locations in 2015.

Strategic Radiology now represents over 40 privately owned, independent practices employing 1,800-plus physicians. Most recently, Wake Radiology in Raleigh, North Carolina, and its 60 rads joined SR earlier this month.
