Largest imaging center corporations in the U.S. 

The medical imaging market is one of the fastest-growing and profitable segments of the healthcare industry year-over-year. 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 the launch of new and innovative equipment, an increase in demand for preventative diagnostic screenings and an increasing population of older adults in the U.S. 

And big medical imaging corporations are noticing the shifts in the market and are making moves to stay ahead of (and even capitalize on) these changes. Many corporations, such as the ones listed below, are investing in and acquiring new diagnostic imaging centers, which can likely lead to even more innovation.  

Here is a list of the 10 largest imaging center corporations ranked by the number of member centers within their network.

What is an imaging exam? 

An imaging exam is a type of test that makes detailed pictures of areas inside a patient’s body.  

Traditional diagnostic imaging tests include mammograms, MRIs and CT scans which are all painless, noninvasive approaches to creating multiple cross-sectional images of a patient’s body. Physicians then use these images to make more accurate diagnoses and more effectively treat medical conditions.  

What is the difference between radiology and medical imaging? 

Radiology is a branch of medicine. Radiologists, who practice radiology, use medical imaging equipment to treat and diagnose patients with certain diseases or conditions.  

When you think about radiology, it’s likely that “radiation” is the first thing that comes to mind. And while radiology may use radiation in some tests, this isn’t always the case. X-rays, one of the most common imaging tests, uses low-dose radiation in order to produce images of the bones and joints. Ultrasounds, however, use high-frequency sound waves to create images of various structures within the body without the need for radiation.  

What is an imaging center corporation?

Large radiology firms like RadNet or Touchstone Medical Imaging are also considered to be imaging center corporations. These companies own and operate dozens or hundreds of outpatient diagnostic imaging centers across their sales territories through corporate acquisition.
