            Digirad Announces Successful Completion of Clinical
        Testing of Its Mobile Cardius(R)-3 Camera and Plans for
                Phased Upgrade of Its Mobile DIS Fleet

    POWAY, Calif.--(BUSINESS WIRE)--Dec. 29, 2005--Digirad Corporation
(NASDAQ:DRAD), a leading provider of cardiovascular imaging services and
solid-state nuclear medicine imaging products to physician offices, hospitals
and imaging centers, announced today the successful completion of the clinical
testing of its mobile Cardius-3M imaging system. Digirad's subsidiary, Digirad
Imaging Solutions (DIS), said that it plans to upgrade its fleet of mobile
imaging systems over the next three years with this proprietary triple-head
digital gamma camera. Digirad anticipates that the first Cardius-3M systems will
be placed into regular operation in DIS in the first quarter of 2006.
    "The upgrade of our DIS fleet is an important element of our strategy to
bring the benefits of Digirad's most advanced mobile cardiac imaging technology
to our DIS physician clients and their patients," said Chief Executive Officer
Gary Burbach. "The Cardius-3M offers excellent image quality and faster imaging
compared to traditional single and dual-head camera systems, which we believe
will enhance workflow during the servicing day and increase DIS customer
satisfaction. We also expect the Cardius-3M to create efficiencies in delivering
the DIS service, as faster imaging should result in shorter work days for our
technologists, reducing direct labor costs and employee turnover and helping to
offset the anticipated higher system costs."
    Mark Casner, President of DIS, added, "Our leadership in mobile nuclear
cardiac imaging has supported a growing stream of revenue for Digirad. Together
with our programs to increase the effectiveness of our sales efforts and address
a lengthening sales cycle, we expect the roll-out of our Cardius-3M system to
our DIS fleet to enhance our position in this market."
    In connection with the DIS fleet upgrade, the Company said that it expects
to report a non-cash charge of approximately $1.1 million in the fourth quarter
ending December 31, 2005 related to a reduction in the depreciable life of its
current DIS cameras to five years. Accordingly, while the Company continues to
expect revenue for the fourth quarter of 2005 to be between $16.2 million and
$17.0 million, it now anticipates the fourth quarter loss to be between $3.5
million and $4.1 million. For 2006, the Company anticipates incremental
depreciation expense of approximately $1.0 million, of which approximately
$700,000 is expected to be reflected in the Company's financial results for the
year's first half. Digirad said that it expects to invest between $4.0 million
and $5.0 million on the fleet upgrade during 2006.
    Mr. Casner said, "We are pleased to bring our newest imaging technology to
our valued DIS customers and believe that by doing so, we will also be able to
increase our operational efficiencies in DIS. This is a significant element of
our plan to improve our overall performance during 2006 and beyond."
