RadNet Reports Third Quarter Financial

California, November 9, 2012 - RadNet, Inc. (NASDAQ: RDNT), a national leader in providing

high-quality, cost-effective, fixed-site outpatient diagnostic imaging services through a network of 236 owned and/or operated

outpatient imaging centers (inclusive of 21 facilities held in Joint Ventures), today reported financial results for its

third quarter of 2012.

Third Quarter Financial Results

For the third quarter of 2012, RadNet reported

Revenue, Adjusted EBITDA(1) and Net Income Attributable to RadNet, Inc. Common Stockholders ("Net Income")

of $167.0 million, $28.6 million and $5.1 million, respectively. Revenue increased $18.4 million (or 12.4%), Adjusted

EBITDA(1) increased $1.6 million (or 6.0%) and Net Income increased $5.0 million over the third quarter of 2011. Net

Income for the third quarter was $0.13 per diluted share, compared to a Net Income of $0.00 per diluted share in the third quarter

of 2011 (based upon a weighted average number of diluted shares outstanding of 39.9 million and 38.5 million for these periods

in 2012 and 2011, respectively). Excluding a $2.8 million gain in the third quarter of 2012 from the de-consolidation of a joint

venture, net income increased from $0.00 per share in the third quarter of 2011 to $0.06 per share in the third quarter of 2012.

results in the third quarter of 2012 were certain non-cash expenses and non-recurring items including: $2.8 million gain from the

de-consolidation of a joint venture, $433,000 of non-cash employee stock compensation expense resulting from the vesting of certain

options, warrants and restricted stock; $66,000 of severance paid in connection with headcount reductions related to cost

savings initiatives from previously announced acquisitions; $45,000 gain on the disposal of certain capital equipment; $767,000

of non-cash Deferred Financing Expense related to the amortization of financing fees paid as part of our existing credit facilities;

and $1.2 million fair value gain from our interest rate swaps, net of the amortization of an Accumulated Comprehensive Loss existing

prior to April 6, 2010.

For the third quarter of 2012, as compared

to the prior year's third quarter, MRI volume increased 16.0%, CT volume increased 15.3% and PET/CT volume increased 15.9%.

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

10.2% 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 2012 and 2011, MRI volume increased 2.7%, CT volume was flat and PET/CT volume decreased 0.1%. Overall

same-center volume, taking into account routine imaging exams, inclusive of x-ray, ultrasound, mammography and other exams, decreased

2.2% over the prior year's same quarter.

Dr. Howard Berger, President and Chief Executive

Officer of RadNet, commented "Our business remains steady and continues to consistently perform in a difficult economic environment.

During the third quarter, we drove significant increases in Revenue, Adjusted EBITDA(1) and Net Income. In particular,

we achieved Net Income of $5 million in the quarter as compared to a breakeven quarter last year."

Dr. Berger continued, "Furthermore, during

the third quarter of 2012, we had 63 business days of operation compared with 64 work days during last year's third quarter.

Our metrics have always been very sensitive to the number of business days of operation in the calendar quarters. While our same

center volumes and revenue on a per day basis were very consistent with last year's third quarter, having one less business

day of operation this quarter affected these metrics by an estimated 1.5% in aggregate for the quarter. The impact on the quarter's

Adjusted EBITDA(1) from this issue is even more pronounced since many of our costs are fixed. Fortunately, this phenomena

reverses in the fourth quarter of this year, where we have one additional business day as compared with the fourth quarter of 2011."

Dr. Berger continued, "Shortly after

the close of the third quarter, on October 10th, we completed a very successful refinancing of our senior term loan and revolving

credit facility. Not only were we able to slightly reduce the cost of these facilities and push-out their maturities until 2017

and 2018, but the credit agreement provides us with materially more flexibility to continue to grow our business into the future.

The refinancing further positions us to remain the principal consolidator in our markets, while allowing us to drive strong free

cash flow to further grow and to deleverage our balance sheet. The combination of the lower cost of our new facilities along with

the expiration of our interest rate swaps in less than a week should provide us with over $7 million of additional free cash flow

in 2013 relative to 2012."

Nine Month Financial Results

For the nine months ended September 30, 2012,

RadNet reported Revenue, Adjusted EBITDA(1) and Net Income of $507.3 million, $89.1 million and $7.9 million, respectively.

Revenue increased $61.2 million (or 13.7%), Adjusted EBITDA(1) increased $5.9 million (or 7.1%) and Net Income

increased $5.2 million over the first nine months of 2011. Net Income for the nine month period ended

September 30, 2012 was $0.20 per diluted share, compared to Net Income of $0.07 per diluted share in corresponding nine month period

of 2011 (based upon a weighted average number of fully diluted shares outstanding of 39.2 million and 39.1 million for these periods

in 2012 and 2011, respectively).

results in the first nine months of 2012 were certain non-cash expenses and non-recurring items including: $2.8 million gain from

the de-consolidation of a joint venture, $2.1 million of non-cash employee stock compensation expense resulting from the vesting

of certain options, warrants and restricted stock; $678,000 of severance paid in connection with headcount reductions related

to cost savings initiatives from previously announced acquisitions; $255,000 loss on the disposal of certain capital equipment;

$2.3 million of non-cash Deferred Financing Expense related to the amortization of financing fees paid

as part of our existing credit facilities; and $3.4 million fair value gain from our interest rate swaps, net of the amortization

of an Accumulated Comprehensive Loss existing prior to April 6, 2010.

Dr. Berger added, "Hurricane Sandy has

had an impact on the lives of millions of Americans. We are pleased to report that all of our East Coast operations are now back

online. During the storm and for many days after it, our business suffered from site closures, loss of power and the disruption

of normal patient flows because of difficult travel conditions for patients and the impact that the storm had on our referring

physician communities. We continue to assess the effects of Hurricane Sandy on our Eastern operations and are hopeful that the

extra business day in this year's fourth quarter along with the potential for insurance proceeds will help to soften the

impact. Regardless of Sandy's ultimate impact on our business, it should be recognized that the effects are one-time and

non-recurring in nature. Our operations teams have responded wonderfully, causing our facilities to be some of the first medical

operations to return to normalcy in their respective local healthcare communities."

Dr. Berger continued, "Many RadNet employees

were personally affected by the trauma of the storm, including those who are facing extensive personal property damage and disruption

in their daily living conditions. I am very proud that our other employees, including many RadNet employees in California, have

responded by making significant financial donations (which were matched by RadNet) that are earmarked to assist those affected

members of the RadNet family. Our hearts and prayers go out to those RadNet team members and their families who were affected by
