Largest imaging center corporations in the U.S.
The medical imaging market is one of the fastest-growing and most profitable segments of the healthcare industry. In fact, the medical imaging market is estimated to be worth $35B by 2026, according to a recent study by MarketsandMarkets.
There are multiple factors that could be contributing to this growth, including advancements in technology, an increase in demand for preventative diagnostic screenings, and an increasing population of older adults in the U.S. For companies serving this space, the opportunity to support clinical efficiency and patient outcomes has never been greater.
What is an imaging center corporation?
Imaging center corporations are large radiology companies, such as RadNet or Touchstone Medical Imaging, that own and operate extensive networks of outpatient diagnostic imaging centers. These corporations typically grow their footprint through strategic acquisitions, expanding their presence across regions and markets.
As the medical imaging landscape evolves, major players are adapting to stay ahead of the curve. Many are actively investing in new technologies and acquiring additional imaging centers to enhance service offerings, improve patient access, and drive innovation.

Which medical imaging company owns the most imaging centers?
California-based RadNet ranks first on our list, with 347 imaging center members primarily in California as well as Delaware, Florida, Maryland, and New York. The corporation with the second most imaging centers is The US Oncology Network, based in The Woodlands, Texas. This corporation has 129-member imaging centers across more than 18 states. Rounding out the top three is RAYUS Radiology, based out of Minneapolis, Minnesota, with 125 imaging center members across 16 states.
The ten corporations on this list have more than 1,100 member imaging centers, which accounts for about 25% of all imaging centers that belong to a corporation tracked using ImagingView.
What is an imaging exam?
An imaging exam is a diagnostic procedure that produces detailed visual representations of internal structures and organs within the body. These exams are critical tools in modern medicine, enabling clinicians to detect, diagnose, and monitor a wide range of conditions with precision and efficiency.
Common modalities include mammography, magnetic resonance imaging (MRI), and computed tomography (CT), all of which are noninvasive. By generating high-resolution, cross-sectional images, these technologies provide clinicians with the anatomical and sometimes functional insights needed to guide evidence-based clinical decisions and treatment plans.
What is radiology?
Radiology is a specialized branch of medicine focused on the use of medical imaging technologies to diagnose, monitor, and, in some cases, treat disease. Radiologists—physicians trained in interpreting medical images—typically work in hospitals, imaging centers, or integrated health systems, collaborating closely with other clinical specialists to inform patient care.
While radiology is often associated with radiation-based modalities like X-rays and CT scans, the field encompasses a broad spectrum of imaging techniques. These include magnetic resonance imaging (MRI), which uses magnetic fields and radio waves, and ultrasound, which relies on high-frequency sound waves—both of which are radiation-free. The choice of modality depends on the clinical context, patient factors, and the anatomical structures being examined.
Radiology continues to play a central role in advancing diagnostic accuracy, guiding minimally invasive procedures, and supporting personalized treatment approaches across nearly every medical specialty.
