RadNet Reports Fourth Quarter and Full Year 2015 Results

and Releases 2016 Financial Guidance

California, March 14, 2016 - RadNet, Inc. (NASDAQ: RDNT), a national leader in providing high-quality, cost-effective,

fixed-site outpatient diagnostic imaging services through a network of 300 owned and/or operated outpatient imaging centers, today

reported financial results for its fourth quarter and full year ended December 31, 2015.

Fourth Quarter Report:

For the fourth quarter of 2015, RadNet

reported Revenue of $215.7 million, Adjusted EBITDA(1) of $32.6 million and Net Income of $881,000. Revenue increased

$30.2 million (or 16.3%), Adjusted EBITDA(1) increased $608,000 (or 1.9%) and Net Income decreased $3.3 million over

the fourth quarter of 2014.

Net Income for the fourth quarter was $0.02

per diluted share, compared to a Net Income of $0.10 per diluted share in the fourth quarter of 2014. These per share values are

based upon a weighted average number of diluted shares outstanding of 46.5 million in the fourth quarter of 2015 and 44.2 million

of diluted shares outstanding in the fourth quarter of 2014.

Income in the fourth quarter of 2015 were certain non-cash expenses and non-recurring items including: $1.2 million of non-cash

employee stock compensation expense resulting from the vesting of certain options and restricted stock; $1.1 million legal settlement

related to an unusual medical malpractice case; $448,000 of severance paid in connection with headcount reductions related

to cost savings initiatives; $92,000 loss on the disposal of certain capital equipment; $611,000 gain on the sale of imaging centers;

and $1.4 million of amortization of deferred financing fees and discount on issuance of debt related

to our existing credit facilities.

For the fourth quarter of 2015, as compared

with the prior year's fourth quarter, MRI volume increased 14.2%, CT volume increased 12.0% and PET/CT volume increased 12.7%.

Overall volume, taking into account routine imaging exams, inclusive of x-ray, ultrasound, mammography and other exams, increased

16.2% over the prior year's fourth quarter. On a same-center basis, including only those centers which were part of RadNet

for both the fourth quarters of 2015 and 2014, MRI volume increased 4.8%, CT volume increased 5.8% and PET/CT volume increased

3.3%. Overall same-center volume, taking into account routine imaging exams, inclusive of x-ray, ultrasound, mammography and other

exams, increased 3.0% over the prior year's same quarter.

Dr. Howard Berger, President and Chief

Executive Officer of RadNet, commented "We made a number of strides in the fourth quarter, many of which position us for

improved performance during 2016. The most important one was related to integrating our recently acquired operations of Diagnostic

Imaging Group and New York Radiology Partners. For acquisitions of this magnitude, it often takes two to three quarters of focused

attention from all of our operational disciplines to right-size and optimize these businesses. Among other things, efforts include

migrating billing and site-level clinical systems, evaluating, training and enhancing the capabilities of personnel, revamping

marketing and branding strategies and migrating supply relationships and vendor contracts."

Dr. Berger continued, "During the

quarter, we also made a final push to complete the migration of certain information technology systems to common platforms. This

included our eRAD clinical operating system and our billing platform. In regards to our billing systems, by the end of the second

quarter of 2016, we will have completed the migration of our financial operations to a new billing software after changing course

mid last year, which led us away from using an alternative provider."

"While I'm happy to report

that we completed much of this necessary heavy-lifting associated with these efforts, the integration of the acquired operations

and the migration of our information technology systems negatively affected the profitability performance of our company during

the quarter. During the quarter, we estimate a $4 million negative impact associated with the expenses related to the Diagnostic

Imaging Group and NYRP integrations as well as the addition of an accounts receivable reserve associated with the collectability

of certain patient accounts affected by the billing system migration. This combined impact was the primary reason for us falling

short of our EBITDA expectations for the quarter and the year."

"While it's not pleasant to

absorb the short term impact from these initiatives, I'm confident there will be no ongoing effects. We expect that both

Diagnostic Imaging Group and NYRP will meet their projections in 2016 and that RadNet will benefit substantially from being on

one information technology platform for each of billing and clinical operations," concluded Dr. Berger.

For full year 2015, the Company reported

Revenue of $809.6 million, Adjusted EBITDA(1) of $121.7 million and Net Income of $7.7 million. Revenue increased

$92.1 million (or 12.8%) and Adjusted EBITDA(1) decreased $4.8 million (or 3.8%). Net Income for 2015 was $0.17 per

diluted share, compared to Net Income of $0.03 per diluted share in 2014 (based upon a weighted average number of diluted shares

outstanding of 45.2 million and 43.1 million in 2015 and 2014, respectively).

Income in 2015 were certain non-cash expenses and non-recurring items including: $7.6 million of non-cash employee stock compensation

expense resulting from the vesting of certain options and restricted stock; $1.1 million legal settlement related to an unusual

medical malpractice case; $745,000 of severance paid in connection with headcount reductions related to cost savings initiatives;

$866,000 loss on the disposal of certain capital equipment; $5.4 gain on the sale of imaging centers; and $5.4

million of amortization and write off of deferred financing fees and discount on issuance of debt related to our existing credit

facilities and refinancing transaction.

For the year ended December 31, 2015, as

compared to 2014, MRI volume increased 12.8%, CT volume increased 13.0% and PET/CT volume increased 6.9%. Overall volume, taking

into account routine imaging exams, inclusive of x-ray, ultrasound, mammography and other exams, increased 12.8% for the twelve

months of 2015 over 2014.

Actual 2015 Results vs. 2015 Guidance:

The following compares the Company's

actual 2015 performance with previously announced revised guidance levels.

2016 Fiscal Year Guidance

For its 2016 fiscal year, RadNet announces

its guidance ranges as follows:

Dr. Berger commented, "As reflected

in our guidance, we are optimistic about 2016. First, 2016 is the first year since 2006 that we will avoid a negative reimbursement

impact from Medicare. This gives us the year to focus on improving our business in the absence of external pressures on pricing.

Second, we will experience the full-year contributions of the New York Radiology Partners and Diagnostic Imaging Group acquisitions,

completed in April and October of last year, respectively. Lastly, in the fourth quarter of 2015, we commenced a number of initiatives

focused on increasing Revenue and lowering costs that should amount to $7-10 million of contribution during 2016. With respect

to Revenues, we are in the midst negotiating for increased capitation rates from several of our newer contracts which began in

late 2014. These contracts negatively impacted our profitability in 2015 because of expenses we incurred related to unanticipated

utilization and capacity issues. Additionally, we are renegotiating certain commercial payer contracts in several of our east coast

markets, which we also anticipate will result in material increases to our Revenue in those regions. Furthermore, additional Revenue

is expected in 2016 from our steady adoption of 3D breast imaging. Medicare is already reimbursing for these services and private

health plans and patients are more willing to incur additional cost to have these more advanced procedures."

Dr. Berger continued, "With respect

to costs, we are working on a number of initiatives to lower our operating expenses. These include projects to lower costs related

to telecommunications and connectivity, equipment service (most notably on our routine imaging), savings from medical supply vendors

and employee health plan efficiencies. While I'm certain that these revenue and enhancements and cost savings are available

to the company, the key for our management team is to execute these initiatives as quickly as possible so that more of their benefits

can be realized during 2016."
