                                       FOR
                         ANNUAL MEETING OF STOCKHOLDERS
                            TO BE HELD JUNE 10, 2003

                SOLICITATION, VOTING AND REVOCABILITY OF PROXIES

GENERAL

    The Board of Directors of Radiologix, Inc. ("Radiologix" or the "Company")
is soliciting the accompanying proxy card for use at the Company's Annual
Meeting of Stockholders to be held on Tuesday, June 10, 2003, at 8:00 a.m.
Dallas, Texas, time (the "Annual Meeting") and at any adjournments of the Annual
Meeting, for the purposes set forth in this proxy statement and in the
accompanying Notice of Annual Meeting of Stockholders. The Annual Meeting will
be held at 2200 Ross Avenue, 39th Floor, Dallas, Texas 75201-2776. The Company's
telephone number is (214) 303-2776. This proxy statement, the accompanying proxy
card and a copy of the Company's 2002 Annual Report to Stockholders are first
being sent or given to stockholders on or about April __, 2003.

RECORD DATE; OUTSTANDING SHARES

    Stockholders of record at the close of business on April 28, 2003 (the
"Record Date"), are entitled to notice of and to vote at the Annual Meeting and
any adjournments. On the Record Date, 21,695,153 shares of the Company's Common
Stock, par value $.0001 per share ("Common Stock"), were issued and outstanding.

REVOCABILITY OF PROXIES

    Any proxy given in response to this solicitation may be revoked by the
person giving it at any time before it is voted. Proxies may be revoked before
they are voted at the Annual Meeting by (i) filing a written notice of
revocation bearing a later date than the accompanying proxy card with the
Company's Secretary (Paul M. Jolas), (ii) executing a later dated proxy card
relating to the same shares and delivering it to the Company's Secretary before
or at the Annual Meeting or (iii) attending the Annual Meeting and voting in
person. Attendance at the Annual Meeting will not in and of itself constitute
revocation of a proxy.

VOTING AND SOLICITATION

    Each share of Common Stock is entitled to one vote for each director to be
elected and upon all other matters submitted for a vote at the Annual Meeting.
Cumulative voting for the election of directors is not permitted.

    Radiologix will pay the cost of soliciting proxies. In addition to
soliciting proxies by mail, Radiologix may solicit proxies by personal
interview, telephone, and similar means. No director, officer, or employee of
Radiologix will be specially compensated for these activities. [Radiologix has
retained ______________, a proxy soliciting firm, to assist in the solicitation
of proxies. ______________'s solicitation fee is $_______, plus reimbursement of
certain out-of-pocket expenses.]

QUORUM; ABSTENTIONS, BROKER NON-VOTES

    The required quorum for transacting business at the Annual Meeting is the
presence in person or by proxy of a majority of the shares eligible to be cast
by holders of Common Stock issued and outstanding on the Record Date. Shares
voted "FOR," "AGAINST" or "ABSTAIN" are treated as being present at the meeting
for purposes of establishing a quorum. They are also treated as shares entitled
to vote at the Annual Meeting (the "Votes Cast").

    While no definitive Delaware statutory or case law addresses the proper
treatment of abstentions, we believe that abstentions should be counted to
determine the total number of Votes Cast with respect to a proposal (other than
the election of directors). In the absence of a controlling precedent to the
contrary, we intend to treat abstentions the same as a vote against a proposal.



                                       2


    Brokers who hold shares in street name for customers generally may not vote
on certain matters unless they have received instructions from beneficial
owners. Brokers who do not receive instructions, however, may vote on the
election of directors. In this proxy statement, "broker non-votes" means votes
that brokers could have cast on other matters with respect to uninstructed
shares if the brokers had received their customers' instructions. The Delaware
Supreme Court has held that, while broker non-votes should be counted to
determine the presence or absence of a quorum, broker non-votes should not be
counted in determining the number of Votes Cast with respect to a particular
proposal on which a broker has expressly not voted. Radiologix intends to treat
broker non-votes in this manner. Accordingly, a broker non-vote will not have
any effect on the outcome of the voting on proposals other than the proposal to
approve an amendment to the Amended and Restated Certificate of Incorporation. A
broker non-vote will have the effect of a vote against approval of that
amendment.


                        PROPOSAL I: ELECTION OF DIRECTORS

NOMINEES

    The Company's Board of Directors consists of six members, each of whom is a
nominee for re-election at the Annual Meeting. Unless otherwise instructed, the
proxy holders will vote all proxies received FOR the Company's nominees named
below. If any nominee becomes unable or declines to serve as a director at the
time of the Annual Meeting, proxies will be voted for any nominee designated by
the present Board to fill the vacancy. Radiologix is not aware of any nominee
who will be unable or will decline to serve as a director. The term of office of
each person elected as a director will continue until the next annual meeting of
stockholders or until his successor has been elected and qualified.

    The nominees' names and certain information about each of them are set forth
below.

                                       4


    The Board has established Audit, Compensation and Stock Plan Administration,
and Nominating Committees to devote attention to specific subjects and to assist
it in the discharge of its responsibilities. The functions of those committees,
their current members and the number of meetings held during 2002 are described
below.

    Audit Committee. The Audit Committee provides the opportunity for direct
communication between the independent public accountants and the Board. The
Audit Committee meets with the certified public accountants periodically to
review their effectiveness during the annual audit program and to discuss the
Company's internal control policies and procedures. Members of the Audit
Committee are Marvin S. Cadwell, Joseph C. Mello and Paul D. Farrell. The Audit
Committee met seven times in 2002.

    Compensation and Stock Plan Administration Committee. The Compensation and

recommendations to the Board regarding salaries and other compensation of
Radiologix executive officers. During the first part of 2002, the nonemployee

                   PROPOSAL II: RATIFICATION OF APPOINTMENT OF
                         INDEPENDENT PUBLIC ACCOUNTANTS

    Ernst & Young LLP has been appointed as the Company's independent public
accountants for 2003, subject to stockholder ratification. Representatives of
Ernst & Young LLP, the Company's independent public accountants for 2002, are
expected to be present at the Annual Meeting with the opportunity to make a
statement if they so desire and to be available to respond to appropriate
questions.

    From the Company's inception through 2001, Arthur Andersen LLP served as the
Company's independent public accountants. As a result of its indictment by the
United States Department of Justice following the bankruptcy of Enron Corp.,
Radiologix released it from future service to the Company effective April 22,
2002. Arthur Andersen LLP's report on the Company's financial statements never
contained an adverse opinion or disclaimer of opinion, nor was it ever qualified
or modified as to uncertainty, audit scope, or accounting principles. Radiologix
and Arthur Andersen LLP never had any disagreement on any matter of accounting
principles or practices, financial statement disclosure or auditing scope or
procedure. The Company's Audit Committee recommended and approved the decision
to release Arthur Andersen LLP.

VOTE REQUIRED

    The affirmative vote of a majority of the shares of Common Stock present in
person or represented by proxy at the Annual Meeting and entitled to vote is
required to ratify the appointment of Ernst & Young LLP.

    THE BOARD RECOMMENDS A VOTE FOR THE PROPOSAL TO RATIFY THE APPOINTMENT OF
ERNST & YOUNG LLP.


AUDIT COMMITTEE REPORT

    The Audit Committee of the Board of Directors (the "Audit Committee")
operates under a written charter adopted by the Board of Directors in June 2000
in accordance with Securities and Exchange Commission and American Stock
Exchange rules. Members of the Audit Committee are Marvin S. Cadwell, Paul D.
Farrell and Joseph C. Mello.





                                       5


    Management is responsible for the Company's internal controls and the
financial reporting process. The independent public accountants are responsible
for performing an independent audit of the Company's consolidated financial
statements in accordance with generally accepted auditing standards and to issue
a report. The Audit Committee's responsibility is to monitor and oversee these
processes. The Audit Committee also recommends to the Board of Directors the
selection of the Company's independent public accountants.

    In this context, the Audit Committee met and held discussions with
management, who represented to the Audit Committee that the Company's
consolidated financial statements were prepared in accordance with accounting
principles generally accepted in the United States. The Audit Committee reviewed
and discussed the consolidated financial statements with both management and the
independent public accountants. The Audit Committee also discussed with the
independent public accountants matters required to be discussed by Statement on
Auditing Standards No. 61 (Communication with Audit Committees). The Company's
independent public accountants also provided the Audit Committee with written
disclosures required by Independence Standards Board Standard No. 1
(Independence Discussions with Audit Committees), and the Audit Committee
discussed with the independent public accountants their independence.

    Based upon the Audit Committee's discussion with management and the
independent public accountants, and the Audit Committee's review of management's
representation and the independent public accountants' report to the Audit
Committee, the Audit Committee recommended that the Board of Directors include
the audited consolidated financial statements in the Company's Annual Report on
Form 10-K for 2002, filed with the Securities and Exchange Commission.

                                       Members of the Audit Committee:
                                       Paul D. Farrell (Chairman)
                                       Marvin S. Cadwell
                                       Joseph C. Mello


INDEPENDENT ACCOUNTANT FEES

    2002 Audit Firm Fee Summary. During 2002, Radiologix retained Ernst & Young
LLP to provide services in the following categories and amounts:


                                       
Audit Fees..............................  $  261,135
Financial Information Systems Design
   and Implementation Fees..............  $        0
All Other Fees*.........................  $   61,886



*   Includes accounting, transaction, and securities regulatory assistance, and
    tax services (compliance, returns, and planning)

    The Audit Committee considered the services that Ernst & Young LLP performed
for Radiologix other than in conjunction with the audit and review of its
consolidated financial statements and determined that those services are
compatible with maintaining Ernst & Young LLP's independence.


       PROPOSAL III: TO APPROVE AN AMENDMENT TO THE COMPANY'S AMENDED AND
                      RESTATED CERTIFICATE OF INCORPORATION

    The Board of Directors has unanimously determined that an amendment to the
Company's Amended and Restated Certificate of Incorporation ("Charter") is
advisable and voted to recommend the amendment to the stockholders for approval.
The proposed amendment to the Charter is summarized and set forth below.

BACKGROUND OF THE PROPOSED AMENDMENT

    Prior to the Company's initial public offering in 1997, the Company's Bylaws
were amended and restated. Among other changes, requirements were added to
Article III, Section 2 of the Bylaws that if the number of members of the Board
of Directors increases to either seven or nine, then at least two or three
members,






                                       6


respectively, must be physicians who provide services to a business acquired by
the Company. The primary reason for this addition to the Bylaws was that many of
the physicians who provide or provided such services received Company Common
Stock in connection with the initial public offering, in exchange for the sale
of their business operations other than the practice of medicine. With so many
physicians holding an equity stake in the Company, this provision provided for
representation of their interests on the Board of Directors.

    Since the Company's Charter provides that the Company's Board of Directors
has the power to amend the Company's Bylaws, and thereby remove the
above-described requirement for physician representation on the Board, the
Company's Charter was also amended. A restriction was added to Article VII of
the Charter that prohibits the Board from altering, amending, or repealing the
Article III, Section 2 Bylaw requirement for physician representation on the
Board.

    In the years following the Company's initial public offering, most of the
doctors who received stock in connection with the initial public offering have
disposed of that stock. As a result, the circumstances that led to the addition
of the Bylaw requirement for physician representation on the Board, and the
addition of the Charter amendment prohibiting the Board from changing the Bylaw
requirement, no longer exist.

    In addition, since the passage of the Sarbanes-Oxley Act of 2002 to impose
certain corporate governance reforms, the New York Stock Exchange and the
American Stock Exchange have proposed rules to require publicly held companies
to elect boards of directors having a majority of independent directors.
Historically, the Company has been of the opinion that directors who are or were
physicians who provide services to a business acquired by the Company are not
independent. If the size of the Company's Board grows, the Bylaw requirement for
physician representation on the Board of Directors would prevent the Company
from having more independent board membership. The Board has no authority to
change this requirement unless the proposed Charter amendment is approved.

    If the Company's stockholders approve the proposed Charter amendment, then
the Board of Directors intends to repeal the Article III, Section 2 Bylaw
requirement for physician representation on the Board.

DESCRIPTION OF THE PROPOSED AMENDMENT

    Article VII of the Company's Amended and Restated Certificate of
Incorporation states as follows:

                  The management of the business and conduct of the affairs of
         the Corporation shall be vested in its Board. The number of directors
         which shall constitute the whole Board shall be fixed by, or in the
         manner provided in, the Bylaws of the Corporation. In furtherance and
         not in limitation of the Board's power to manage the business and
         conduct the affairs of the Corporation, the Board shall have the power,
         upon the affirmative vote of at least a majority of the Directors then
         serving, to adopt, amend or repeal from time to time the Bylaws of the
         Corporation, subject to the right of the stockholders entitled to vote
         thereon to adopt, amend or repeal the Bylaws. Notwithstanding the
         foregoing, the Board shall not have the power to alter, amend or repeal
         THE SECOND OR THIRD SENTENCES OF THE FIRST PARAGRAPH OF ARTICLE III,
         SECTION 2 OF THE BYLAWS REGARDING THE COMPOSITION OF THE BOARD, OR any
         OTHER Bylaw (or Article or Section thereof) that expressly provides
         that it cannot be altered, amended or repealed by the Board.

    The proposed amendment would remove the words highlighted and underlined
above from the text of Article VII of the Charter.

VOTE REQUIRED

    The affirmative vote of a majority of the shares of Common Stock entitled to
vote is required to approve the proposed amendment to Article VII of the
Charter. Brokers holding shares for which beneficial owners do not provide
voting instructions are not entitled to vote to approve the proposed amendment.
Therefore, broker non-votes will have the effect of votes AGAINST this matter.

    THE BOARD RECOMMENDS A VOTE FOR THE PROPOSAL TO APPROVE AN AMENDMENT TO THE
AMENDED AND RESTATED CERTIFICATE OF INCORPORATION.

     (1)  The exercise price may be paid in shares of Common Stock owned by the
          Named Executive, in cash, or in any other form of valid consideration
          as determined by the Compensation Committee in its discretion.

     (2)  Dollar amounts in these columns represent the value that might be
          realized upon exercise of the options immediately before they expire,
          assuming that the market price of Common Stock appreciates from the
          grant date at assumed annual rates of 5% and 10% (compounded annually)
          until the end of the 10-year term. The Securities and Exchange
          Commission prescribed the assumed appreciation rates. They are not
          intended to forecast future appreciation, if any, of the price of the
          Common Stock. These numbers do not take into account option provisions
          for early expiration following termination of employment,
          nontransferability or vesting periods.

EMPLOYMENT CONTRACTS

     Radiologix has employment agreements with Messrs. Linehan, Abbasi, and
Jolas, each of whom receive annual salaries at the rate of $440,000, $286,000,
and $229,500, respectively. Until their termination of employment with
Radiologix, Radiologix also had employment agreements with Messrs. Wagar and
Martin, who received annual salaries at the rate of $442,000 and $338,000,
respectively. Each employment agreement has or had a term of one year with
automatic successive one year renewals. Each employment agreement provides that
if Radiologix terminates the employee (i) other than for cause or (ii) upon
disability, or (iii) if the employee voluntarily terminates employment due to an
adverse change in duties, Radiologix will pay the employee one year's annual
base salary at the most current rate in one lump sum, plus all accrued but
unpaid wages and expense reimbursements. If the employee's employment terminates
following a change in control transaction (as defined in the employment
agreements), then Radiologix will pay the employee two times the employee's most
recent annual base salary and two times the amount of the employee's most recent
bonus, as well as provide up to two years of other employee benefits. Each
employment agreement contains a covenant not to compete with Radiologix for a
period of one year following termination of employment.

     Effective February 4, 2003, Radiologix entered into a six-month consulting
agreement with Mark L. Wagar, its former Chairman of the Board and Chief
Executive Officer. Mr. Wagar is entitled to receive $18,416.67 per month during
which he serves as a consultant to Radiologix.

     Radiologix has also entered into a consulting arrangement with Derace L.
Schaffer, M.D., a member of the Board of Directors. The arrangement is described
in the "Certain Transactions" section of this proxy statement.

DIRECTOR COMPENSATION

     Pursuant to the Company's Amended and Restated Bylaws, Board members may be
compensated in a manner and at a rate determined from time to time by the Board.
Directors who are Radiologix employees do not receive additional compensation
for service as a director. Under the Company's 1996 Stock Option Plan, directors
who are not Radiologix employees receive options to purchase 10,000 shares of
Common Stock per year of service. Non-employee directors are paid a monthly
retainer of $1,000 for Board service, $500 for committee service, and $250






                                       12


for service as a committee chair. They receive $1,000 for personal attendance at
any Board or committee meeting and $500 for attendance by telephone.

    Marvin S. Cadwell was appointed Chairman of the Board effective December 4,
2002. In consideration of his service as Chairman, Mr. Cadwell receives $5,000
per month. He also received an option to purchase 50,000 shares of Radiologix
Common Stock at an exercise price of $4.69, which was the closing price of the
Common Stock on the American Stock Exchange on the date the option was granted.
The option will vest for 30,000 shares on December 4, 2003, and thereafter for
833 shares per month for 24 months.

DEDUCTIBILITY OF COMPENSATION

    Section 162(m) of the Internal Revenue Code limits the tax deduction of a
public company to $1,000,000 for compensation paid to its chief executive
officer or any of its four other highest paid officers. Radiologix has not
adopted a policy with respect to annual executive compensation in excess of
$1,000,000.


                        REPORT ON EXECUTIVE COMPENSATION

COMPENSATION PHILOSOPHY

    The Compensation Committee is composed of independent directors and advisors
who are not employees of Radiologix and who qualify as disinterested persons for
purposes of Section 16(b) under the Securities Act of 1934. The Compensation
Committee is responsible for reviewing all aspects of the Company's executive
compensation programs and administering the Company's 1996 Stock Option Plan. In
addition, the Compensation Committee is responsible for reviewing and
recommending to the Board policies and programs for the development of
management personnel and management structure and organization. Members of the
Compensation Committee are Messrs. Cadwell, Farrell, and Mello. Mr. Mello chairs
Compensation Committee meetings. The Compensation Committee meets during the
fiscal year to establish target base compensation levels for the Company's
executive officers for that year and to finalize bonuses for the previous year's
performance with the concurrence of the Board.

    The Compensation Committee believes that compensation for the Company's
employees, including the Named Executives, must be in amounts sufficient to
attract, retain and motivate employees, while at the same time maintaining a
productive relationship to the Company's service and financial performance.
Moreover, the Compensation Committee believes that compensation decisions should
foster career opportunities for, and aid the development of, employees and
encourage and reward employees who put the Company's interests ahead of their
own.

    The Company's compensation philosophy is based on the following general
principles:

    o   To achieve compensation levels for employees through base salaries and
        bonuses (based on Company and individual performance) to attract and
        retain the most qualified individuals.

    o   To align employees' and stockholders' interests in maximizing
        stockholder value by granting options to purchase Common Stock.

    The nonemployee members of the Board of Directors performed the functions of
the Compensation Committee during the first part of 2002, when decisions
regarding compensation of the Chief Executive Officer and the other Named
Executives were made. In November 2002, Marvin S. Cadwell, Joseph C. Mello, and
Paul D. Farrell were appointed as sole members of the Compensation Committee.

COMPENSATION OF THE CHIEF EXECUTIVE OFFICER AND OTHER EXECUTIVE OFFICERS

    Radiologix entered into an employment agreement with Mark L. Wagar in May
1998 upon his appointment as President and Chief Executive Officer. Mr. Wagar's
employment agreement established a base salary and provided for bonuses
determined by the Compensation Committee. The other Named Executives have
similar agreements.





                                       13


    In 2002, the Board approved salary increases for all of the Named
Executives. The salaries of Messrs. Wagar, Martin, Abbasi, and Jolas were
increased by $17,000, $13,000, $11,000, and $4,500, respectively. These
increases were based upon costs of living increases and executive performance
during 2001.

    In 2002, the Board also approved option grants to all of the Named
Executives. In determining the number of shares to grant under these options,
the Board took into account the Company's performance, individual job
performance, employee morale, and the Company's desire to properly compensate
the executives. No specific weights were assigned to any of these factors.

    In addition, the Company has a Company-wide cash compensation incentive
program designed to encourage all employees to focus on results that will build
sustainable value for patients, other customers and stockholders. The program
gives every employee an opportunity for additional cash compensation if results
are favorable on a variety of factors including patient satisfaction, revenue
growth, EBITDA, days sales outstanding and resource management. Senior managers
and executive officers have an additional factor related to economic value added
based on return on invested capital. No incentive payments were paid to any of
the Named Executives for fiscal year 2002 Company performance.


    Radiologix has entered into an employment agreement with Stephen D. Linehan,
who was appointed President and Chief Executive Officer effective February 4,
2003. Mr. Linehan's employment agreement establishes a base salary of $440,000
per year and includes options to acquire up to 900,000 shares of the Company's
Common Stock.

           COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
                            IN COMPENSATION DECISIONS

    The Company's Board of Directors participated in compensation decisions
during 2002. No director is or has been an officer or employee of any entity on
which any executive officer of Radiologix or its subsidiaries serves as a
director or a member of the compensation committee.


                              CERTAIN TRANSACTIONS

    During 2002, Advanced Radiology, P.A. (the radiology group for which Dr.
Sherman serves as Chairman) and The IDE Group, P.C. (the radiology group for
which Dr. Schaffer serves as a director) paid Radiologix $76,891,719 and
$31,476,269, respectively, in service fees pursuant to the agreements between
Radiologix and each radiology group.

    Derace L. Schaffer, M.D., a member of the Board of Directors, provided
consulting services to Radiologix during March and April 2003. He received
$10,000 for each month that he provided consulting services to Radiologix. As of
the date of this proxy statement, the Board of Directors has not considered or
approved of a consulting arrangement with Dr. Schaffer for future services.


             SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

    Section 16(a) of the Securities Exchange Act of 1934, as amended, requires
the Company's directors, executive officers and beneficial owners of more than
10% of the Common Stock to file with the Securities and Exchange Commission
initial reports of ownership and reports of changes in ownership of Common Stock
and other equity securities of Radiologix. A Form 5 reporting the automatic
grant of a director stock option to Dr. Schaffer upon his re-election as
director in 2002 inadvertently was not filed for 2002. The option award has now
been reported. Based solely upon its review of copies of the forms received,
Radiologix believes that all other such reports were submitted on a timely basis
during 2002.


                              STOCKHOLDER PROPOSALS

    Pursuant to Securities and Exchange Commission rules, stockholder proposals
must be delivered to Radiologix at its principal executive offices no later than
December 31, 2003, to be considered for inclusion in the Company's proxy
statement for the 2004 annual meeting of stockholders. Stockholder proposals
should be directed to Radiologix, Inc., 3600 JP Morgan Chase Tower, 2200 Ross
Avenue, Dallas, Texas 75201-2776, Attention: Chief Executive Officer.


                                     GENERAL

    The 2002 Annual Report to Stockholders, which includes the Company's Report
on Form 10-K, is being mailed to the stockholders with this proxy statement.
