LOS ANGELES, Calif., May 12, 2008 - RadNet, Inc. (NASDAQ: RDNT), a national
leader in providing high-quality, cost-effective diagnostic imaging services
through a network of fully-owned and operated outpatient imaging centers, today
reported financial results for its first quarter ended March 31, 2008.

For its first quarter of fiscal 2008, RadNet reported Revenue and Adjusted
EBITDA(1) of $114.7 million and $22.1 million, respectively. Revenue increased
8.4% (or $8.9 million) and Adjusted EBITDA(1) increased 8.5% (or $1.7 million),
respectively over the prior year's quarter. The results reflect improved volume
in existing centers as well as the contribution of acquisitions and operating
initiatives.

For the first quarter of 2008, as compared to the prior year's quarter, MRI
volume increased 3.3%, CT volume decreased 1.6% and PET/CT volume increased
33.1%. Overall volume, taking into account routine imaging exams, inclusive of
x-ray, ultrasound, mammography and other exams, increased 4.2% over the prior
year's quarter.

Net Loss for the first quarter was $5.5 million, or $(0.15) per share, compared
to a net loss of $5.6 million or $(0.16) per share, reported for the three month
period ended March 31, 2007 (based upon a weighted average number of fully
diluted shares outstanding of 35.7 million and 34.4 million for these periods in
2008 and 2007, respectively). Affecting net income in the first quarter of 2008
were certain non-cash expenses and non-recurring items including:

     o    $951,000  non-cash  loss on the fair  value of  interest  rate  hedges
          related to the Company's credit facilities;
     o    $700,000  expense related to a payment to the settlement of a business
          dispute
     o    $532,000 of Deferred  Financing Expense related to the amortization of
          financing  fees  paid as part of our $405  million  credit  facilities
          drawn  down  in  November  2006  in  connection  with  the  Radiologix
          acquisition  and the  incremental  term  loans  and  revolving  credit
          facility arranged in August 2007 and February 2008;
     o    $454,000 of non-cash  employee stock  compensation  expense  resulting
          from the vesting of certain options and warrants;
     o    Approximately  $400,000 in bonus  compensation paid to our some of our
          physician  groups for their  assistance with our transition to digital
          mammography

(1) Definition of EBITDA, a non-GAAP measure, is found on the last page of this
release.





During this first quarter, RadNet's accomplishments included the following:

     o    Substantially  completing the transition of its Maryland operations to
          digital mammography;
     o    Completing the construction of its second interventional radiology and
          imaging center. This facility, located in Rancho Mirage, CA opened for
          business  during  the  first  week in  May.  It  complements  RadNet's
          portfolio of multi-modality  services in the Palm Springs/Palm  Desert
          market,  a market where RadNet has six other  imaging  facilities  and
          where it has substantial procedural backlogs;
     o    Replacing  two centers  that were  acquired as part of  Radiologix  in
          Yonkers,  NY and Pleasanton,  CA. These centers opened for business in
          May;
     o    Completing the acquisition of the Papastavros Group of imaging centers
          in  the  middle  of  March.   RadNet  also  began  the  transition  of
          Papastavros' operations to digital mammography;
     o    Acquiring the Rolling Oaks imaging centers in Westlake/Thousand  Oaks,
          CA in February;
     o    Expanding two newly  restructured  joint  ventures with Carroll County
          and St. Joe's hospitals in Maryland; and
     o    Installing  five  additional  MRI  systems  within  RadNet's  existing
          operating centers.

"We are pleased with our progress in the first quarter of 2008, not only because
the financial results reflect increasing volumes, revenue and EBITDA from the
prior year's quarter, but also because of our completion of a number of key
operational accomplishments. I believe these operational accomplishments will
set the stage for significant improvement in our financial performance during
the rest of the year." said Dr. Howard Berger, Chairman and Chief Executive
Officer of RadNet.

"Although we have made the investments and incurred operating costs associated
with many of the acquisitions and initiatives we recently completed, our first
quarter results did not include the financial contribution from most of them.
Our reported results do not yet include full-quarter contributions from our
acquisitions of Rolling Oaks and Papastavros, nor do they include a significant
portion of the anticipated benefit from our conversion to digital mammography,
expanded joint venture relationships and five new MRI systems. Additionally, our
results exclude contributions from the acquisition of five imaging centers from
Insight Health, our Breastlink breast oncology acquisitions and related
initiatives and our new interventional radiology and imaging center in Rancho
Mirage, CA." said Dr. Berger. All of these acquisitions and initiatives should
contribute materially to our second quarter and subsequent quarters."

Dr. Berger added, "Our industry continues to present us with growth
opportunities at an accelerating pace. We remain highly selective regarding the
opportunities we pursue, which we require to be consistent with our focused
multi-modality and geographic clustering approach. We continue to believe that
we are extremely well positioned to capitalize on opportunities to grow our
business significantly."

results. The Company believes that, in addition to GAAP metrics, these non-GAAP

provides a basis for measuring the Company's financial condition against other
quarters. Such information should not be considered as a substitute for any

Footnote
- --------


(1) The Company defines Adjusted EBITDA as earnings before interest, taxes,
depreciation and amortization, each from continuing operations and adjusted for
losses or gains on the disposal of equipment, debt extinguishments and non-cash
equity compensation. Adjusted EBITDA includes equity earnings in unconsolidated
operations and subtracts minority interests in subsidiaries, and is adjusted for
non-cash or extraordinary and one-time events taken place during the period.


Adjusted EBITDA is reconciled to its nearest comparable GAAP financial measure.
Adjusted EBITDA is a non-GAAP financial measure used as analytical indicator by
RadNet management and the healthcare industry to assess business performance,
and is a measure of leverage capacity and ability to service debt. Adjusted
EBITDA should not be considered a measure of financial performance under GAAP,
and the items excluded from Adjusted EBITDA should not be considered in
isolation or as alternatives to net income, cash flows generated by operating,
investing or financing activities or other financial statement data presented in
the consolidated financial statements as an indicator of financial performance
or liquidity. As Adjusted EBITDA is not a measurement determined in accordance
with GAAP and is therefore susceptible to varying methods of calculation, this
metric, as presented, may not be comparable to other similarly titled measures
of other companies.
