Imaging Center Consolidation Wave Continues, With Challenges
A new era of consolidation is underway in the outpatient imaging and ASC sector, as private equity firms and large chains pursue acquisitions to gain scale and payer leverage. However, some physician-owned platforms are experiencing "deal fatigue" and questioning the promised financial synergies, with some groups even unwinding previous deals.
- The shift of imaging services to lower-cost, outpatient settings is a significant trend, with approximately 40% of all radiology volume now occurring in outpatient centers rather than hospitals. This move is driven by the convenience and cost-effectiveness of these centers. Health systems are responding by acquiring or partnering with freestanding imaging centers to recapture patient volume. - Reimbursement changes are a major factor in this trend, with Medicare payment rates for physicians, including radiologists, seeing a 2.9% average decrease in 2025. Concurrently, the gap between what Medicare pays for services in a hospital outpatient department versus a physician's office has widened significantly, from a 12% difference in 2011 to a 40% difference in 2021 for the median service. - Private equity firms are increasingly active in the imaging sector, with notable 2025 deals including Capitol Imaging's acquisition of Houston MRI & Diagnostic Imaging and Outpatient Imaging LLC, and Panos Partners' acquisition of Desert Imaging. This interest is fueled by opportunities for geographic expansion and service line consolidation. - Major players in the imaging market continue to expand their footprint through acquisitions. RadNet, for example, entered the Midwest market by acquiring six outpatient centers from Northwest Radiology and also acquired seven centers in the Houston area. Similarly, RAYUS Radiology expanded its presence in Central Florida by acquiring Sand Lake Imaging. - The mobile medical imaging services market is projected to grow from USD 17.31 billion in 2026 to USD 21.13 billion by 2031. Key companies in this sector include Akumin Inc., DMS Health Technologies, and Front Range Mobile Imaging. Recent activity includes DMS Health's acquisition of Advanced Imaging Management. - The FDA is rapidly approving AI-enabled medical devices, with the total number reaching 882 as of May 2024; nearly 80% of these are for medical imaging. From August 2023 to March 2024 alone, 151 new AI/ML-enabled devices were cleared. - In response to the proliferation of AI, the American College of Radiology (ACR) has released draft practice parameters to provide a national framework for its integration into clinical practice. The ACR has also developed programs like ARCH-AI to set standards for the safe and effective use of AI in imaging. - While the FDA has cleared a significant number of AI/ML-enabled devices, reimbursement from the Centers for Medicare & Medicaid Services (CMS) has been approved for only about 10 of them, creating a gap between regulatory approval and clinical payment.
