      RE:  REGISTRATION OF SECURITIES OF MEDQUEST, INC.

Ladies and Gentlemen:

      Reference is made to the Registration Statement (the "Registration
Statement") on Form S-4 (File No. 333-101399) of MedQuest, Inc., a Delaware
Corporation (the "Company"), in connection with the Company's offer (the
"Exchange Offer") to exchange up to $180,000,000 principal amount of the
Company's 11 7/8 % Senior Subordinated Notes due 2012 that have been registered
under the Securities Act of 1933 (the "New Notes"), which New Notes will be
guaranteed (the "Guarantee") by, among others, Kansas Diagnostic Imaging, Inc.,
a Kansas corporation (the "Kansas Guarantor"), for a like principal amount of
the Company's outstanding 11 7/8 % Senior Subordinated Notes due 2012 (the "Old
Notes"), which Old Notes have also been guaranteed by such guarantor.

      We have acted as counsel to the Kansas Guarantor in connection with the
above transaction. We have examined originals or copies, certified or otherwise
identified to our satisfaction, of such documents, corporate company records,
certificates of public officials and other instruments we have deemed necessary
or advisable for the purpose of rendering this opinion, including, without
limitation, the Officer's Certificate of the Secretary and Treasurer of the
Kansas Guarantor dated February 13, 2003.

      Upon the basis of the foregoing, and assuming compliance with all
applicable federal and state securities laws, we are of the opinion that when
the New Notes have been duly executed, authenticated and delivered in accordance
with the Indenture dated as of August 15, 2002, as supplemented (the
"Indenture"), among Company, MQ Associates, Inc., as guarantor, the Subsidiary
Guarantors parties thereto and Wachovia Bank, National Association, as Trustee,
in exchange for the Old Notes in accordance with the Indenture and the Exchange
Offer, the Guarantee of the Kansas Guarantor will be the legally valid and
binding obligations of the Kansas Guarantor.
