RadNet Reports Third Quarter Financial

California, November 9, 2015 - RadNet, Inc. (NASDAQ: RDNT), a national leader in providing

high-quality, cost-effective, fixed-site outpatient diagnostic imaging services through a network of 297 owned and/or operated

outpatient imaging centers, today reported financial results for its third quarter of 2015.

Dr. Howard Berger, President and Chief Executive

Officer of RadNet, commented, "We are pleased with the continuing improvement of our business since the first quarter of

this year. This third quarter, we had our highest Revenue and EBITDA of 2015, reflective of growth and expansion initiatives we

completed throughout the year and continued focus on managing costs. Although we are far from the full optimization of the infrastructure

investments we made at the end of last year and throughout the first quarter of 2015, we are beginning to experience some of the

operating leverage from the increased capacity these investments provided. Despite having more work to do to grow into this infrastructure,

I am encouraged by utilization trends that I see in our business."

"I'm most encouraged by strong

volumes we are experiencing in many of our regional networks. Aggregate volumes increased 12.0% and same center volume increased

5.2% as compared with last year's third quarter. Capitation in California continues to grow as well. As compared with last

year's third quarter, capitation revenue increased 21.5%," added Dr. Berger.

Dr. Berger continued, "During the quarter,

we completed the expansion of our New Jersey Imaging Joint Venture with Barnabas Health and established a new joint venture in

the Baltimore, Maryland region with LifeBridge Health. Partnering with hospitals and health systems will continue to be an important

part of our growth strategy. The Affordable Care Act encourages alliances between providers, and hospitals and health systems are

more interested than ever in aligning with ancillary outpatient service providers like RadNet. These partnerships validate our

expertise in all facets of imaging, from operating outpatient centers to managing in-hospital radiology departments, providing

information technology solutions and provisioning off-site teleradiology services. "

"Subsequent to the end of the third quarter,

we completed the acquisition of Diagnostic Imaging Group, LLC ("DIG" ). DIG should incrementally provide us over $70

million of annual revenue, over 750,000 patient exams per year and 17 new facilities in densely populated New York metropolitan

markets. The acquisition enhances our already-leading position in the New York metropolitan area, bolstering our presence in Brooklyn,

Manhattan and the Bronx, while establishing us in Queens. The acquisition furthers our ability to pursue unique contracting and

population health opportunities, and I believe there are substantial additional growth opportunities on which we can capitalize;"

concluded Dr. Berger.
