RadNet Reports Third Quarter Financial Results and Reaffirms

Previously Announced 2018 Guidance Levels

LOS ANGELES, California, November 9,

2018 - RadNet, Inc. (NASDAQ: RDNT), a national leader in providing high-quality, cost-effective,

fixed-site outpatient diagnostic imaging services through a network of 341 (adjusted for centers added on October 1, 2018 related

to the previously announced Medical Arts Imaging and EmblemHealth transactions) owned and/or operated outpatient imaging centers,

today reported financial results for its third quarter of 2018.

Dr. Howard Berger, President and Chief

Executive Officer of RadNet, commented, "I am pleased with our results this quarter. We compared favorably in all metrics

relative to last year's third quarter. We demonstrated Revenue, Adjusted EBITDA(1) and earnings growth as well

as positive same center revenue and procedural increases."

Dr. Berger continued, "Immediately

after quarter-end, we completed two important initiatives that further our strategy in New York and set the stage for growth in

the coming quarters. First, under a capitation arrangement we announced in August, we commenced operations on October 1st to provide

imaging to approximately 200,000 members of EmblemHealth's AdvantageCare Physicians medical group in Long Island and the

boroughs of New York City. The contract included RadNet assuming operations in 26 AdvantageCare offices. During this third quarter,

we hired and trained the employees needed to staff the new offices and procured the equipment necessary to support the anticipated

patient volumes. While capitation has been an important and successful aspect of our operating strategy in California, this is

our first inroad into risk-based contracting on the east coast. We are in discussions with other east coast medical groups and

payors about network contracting and population health opportunities and are very interested in expanding through managing the

imaging for larger patient populations."

Dr. Berger added, "The second transaction

in New York, the acquisition of Medical Arts Imaging, was completed on October 1st and expanded our New York metropolitan network

into Nassau and Suffolk counties of Long Island. The ten centers of Medical Arts are instrumental in providing the capacity and

coverage necessary to effectively service the EmblemHealth capitated members. Expanding our platform into Long Island with EmblemHeatlh

and Medical Arts has already surfaced additional opportunities to grow our operations in New York. Launching this capitation contract

and integrating both the Medical Arts and AdvantageCare locations into the RadNet network will be our primary area of focus for

the remainder of the year."
