About Radiology Partners
Radiology Partners operates as a physician-led and physician-owned radiology practice in the United States. It was co-founded in 2012 by Rich Whitney and Dr. Anthony Gabriel, who identified an opportunity to consolidate and transform the fragmented radiology market. Whitney, the Chairman and CEO, brought a strong background in healthcare services and finance, having previously been the CFO of DaVita Inc. His experience includes leading, founding, and investing in various healthcare companies. Co-founder Dr. Gabriel, a seasoned healthcare executive and physician, served as the practice's President and Chief Operating Officer, combining clinical expertise with business acumen from his time at DaVita and an MBA from UCLA.
Read full description
The company's business model is centered on a B2B strategy, partnering with hospitals, imaging centers, clinics, and other healthcare facilities to manage their radiology services. This model allows individual radiology practices to join Radiology Partners' larger network, gaining access to significant resources while maintaining local physician leadership and a degree of autonomy. Revenue is primarily generated through fee-for-service arrangements with these healthcare providers and payers for diagnostic and interventional radiology services. The company provides its partners with comprehensive support, including clinical and leadership development, IT infrastructure, data analytics, recruitment, billing, and legal services.
Radiology Partners offers a wide array of services, including diagnostic imaging interpretation, interventional radiology, and teleradiology, with a focus on providing subspecialty expertise around the clock. To address rising imaging demand and workflow inefficiencies, the company has invested in technology, recently launching Mosaic Clinical Technologies. This division features MosaicOS, a proprietary, cloud-native operating system that integrates AI-powered tools and smart workflows. Key features include 'Mosaic Reporting,' which uses ambient voice AI and LLMs to automate report structuring, and 'Mosaic Drafting,' which employs multimodal AI to pre-draft X-ray reports, allowing radiologists to focus on image interpretation. Serving thousands of healthcare facilities across all 50 states, the practice has grown substantially through strategic acquisitions and partnerships, becoming the largest radiology practice in the U.S.
