RadNet Reports Third Quarter

LOS ANGELES, California,

November 11, 2013 - RadNet, Inc. (NASDAQ: RDNT), a national leader in providing high-quality, cost-effective, fixed-site

outpatient diagnostic imaging services through a network of 251 owned and/or operated outpatient imaging centers, today reported

financial results for its third quarter of 2013.

Third Quarter Financial

For the third quarter of

2013, RadNet reported Revenue, Adjusted EBITDA(1) and Net Loss Attributable to RadNet,

Inc. Common Stockholders ("Net Loss") of $175.2 million, $25.4 million and $(467,000), respectively. Revenue increased

$14.7 million (or 9.2%), Adjusted EBITDA(1) decreased $3.2 million (or 11.3%) and

Net Income decreased $2.7 million (adjusting for the $2.8 million gain in the third quarter of 2012 from the deconsolidation of

a joint venture), respectively, over the third quarter of 2012. Net Loss for the third quarter was $(0.01) per diluted

share, compared to a Net Income of $0.06 per diluted share in the third quarter of 2012 (again adjusting for the gain from the

deconsolidation of the joint venture). These per share values are based upon a weighted average number of diluted shares

outstanding of 39.2 million and 39.9 million for these periods in 2013 and 2012, respectively.

Affecting operating results

in the third quarter of 2013 were certain non-cash expenses and non-recurring items including: $463,000 of non-cash

employee stock compensation expense resulting from the vesting of certain options and restricted stock; $72,000 of severance paid

in connection with headcount reductions related to cost savings initiatives from previously announced acquisitions; $5,000 gain

on the disposal of certain capital equipment; and $1.2 million of non-cash amortization of deferred loan costs and discount on

issuance of debt as part of our existing credit facilities.

For the third quarter of

2013, as compared to the prior year's third quarter, MRI volume increased 12.7%, CT volume increased 3.7% and PET/CT volume

decreased 0.3%. Overall volume, taking into account routine imaging exams, inclusive of x-ray, ultrasound, mammography

and other exams, increased 12.0% over the prior year's third quarter. On a same-center basis, including only those

centers which were part of RadNet for both the third quarters of 2013 and 2012, MRI volume decreased 2.2%, CT volume increased

1.6% and PET/CT volume increased 1.8%. Overall same-center volume, taking into account routine imaging exams, inclusive

of x-ray, ultrasound, mammography and other exams, was flat over the prior year's same quarter.

Dr. Howard Berger, President

and Chief Executive Officer of RadNet, commented "We have been experiencing pressured reimbursement and lower than anticipated

utilization all year. The lower utilization and pricing of imaging services has not been unique to RadNet and has been

an industry-wide phenomenon in the outpatient, free-standing marketplace during 2013."

combination of pricing and utilization declines, we have worked hard to create and begin executing a cost savings program targeted

at saving $30 million of annual operating costs. Some of the initiatives comprising this plan have been implemented

during the third quarter or will be implemented by year-end, which will provide us with a full-year's impact of their benefits

in 2014. Other initiatives will be implemented during 2014. Areas of savings include elimination of salaries

and personnel, savings from Information Technology implementations (including our continued migration to eRAD RIS and PACS and

voice recognition transcription), certain supplies and purchasing programs and corporate savings from changes to our workers compensation,

healthcare and property and casualty insurance, commercial banking fees and physician compensation."

result of our continual efforts to mitigate industry pressures. Unfortunately, we were unable to affect some of these

programs in the last three quarters, which resulted in our performance lagging behind our expectations. Our focus is

for these initiatives to outpace the continuing pressures in 2014, so that 2014 will show, in addition to continued aggregate revenue

growth, improvements in EBITDA and profitability. I'm further encouraged by very strong volumes we have experienced

in the fourth quarter so far, relative to last year's same period," added Dr. Berger.

Nine Month Financial

For the nine months ended

September 30, 2013, RadNet reported Revenue, Adjusted EBITDA(1) and Net Income of

$524.6 million, $81.0 million and $877,000, respectively. Revenue increased

$36.8 million (or 7.6%), Adjusted EBITDA(1) decreased $8.1 million (or 9.1%) and

Net Income decreased $4.2 million (adjusting for the $2.8 million gain in the third quarter of 2012 from the deconsolidation of

a joint venture), respectively, over the first nine months of 2012. Net Income for the nine month period ended September

30, 2013 was $0.02 per diluted share, compared to Net Income of $0.13 per diluted share in corresponding nine month period of 2012

(again adjusting for the gain from the deconsolidation of the joint venture). These per share values are based upon

a weighted average number of fully diluted shares outstanding of 39.9 million and 39.2 million for these periods in 2013 and 2012,

Affecting operating results

in the nine months ended September 30, 2013 were certain non-cash expenses and non-recurring items including: $2.0 million

of non-cash employee stock compensation expense resulting from the vesting of certain options and restricted stock; $312,000 of

severance paid in connection with headcount reductions related to cost savings initiatives from previously announced acquisitions;

$357,000 loss on the disposal of certain capital equipment; and $3.3 million of non-cash amortization of deferred loan costs and

discount on issuance of debt as part of our existing credit facilities.

RadNet has revised its previously

announced 2013 fiscal year guidance ranges:

Dr. Berger added, "The

challenges we've experienced in our same center revenue performance has caused us to revise downward our Adjusted EBITDA

projections and Free Cash Flow Generation guidance levels for 2013. While I'm confident that the costs savings

plans we are implementing will help mitigate in 2014 the challenging utilization and pricing environment, the effects of these

challenges have impacted our same center performance this year."

"Aside from operational

changes and cost reductions, we continue to pursue opportunities to lower our cost of capital. This includes evaluating

refinancing plans for our 10 3/8% senior unsecured notes, which become callable in April of next year. Lowering our

interest expense will allow us to have more cash flow to deleverage our balance sheet through debt paydown or expand our EBITDA

through acquisitions and investments that we would otherwise fund through future borrowings. We anticipate building

a cash balance at the end of 2013 of between $5 million and $10 million. This is the result of expected incremental

free cash flow in the fourth quarter resulting from having front-loaded the vast majority of our capital expenditures in the first

three quarters of 2013."
