Item 3    SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

      Mr. Smolik and Drs. Wachter, Dees, Fisher and Scott acquired their 
Common Stock from the Issuer on May 16, 1997 as a result of the merger 
between Photogen, Inc. (of which they were  the sole stockholders) and a 
wholly-owned subsidiary of Issuer.  The consideration for the Common Stock 
Mr. Smolik and Drs. Wachter, Dees, Fisher and Scott received from the Issuer 
was their interest in Photogen, Inc. 

      Dr. Weinstein and his wife acquired 3,239,350 shares of Common Stock on 
December 9, 1994 from the Issuer in a private transaction (adjusted to 
reflect a subsequent two-for-one reverse stock split).  The purchase price 
was $.0231528 per share, which Dr. Weinstein and his wife paid with their 
personal funds.

                                      -14-
<PAGE>

      On May 16, 1997, the Issuer sold 2,975,359 shares of Common Stock to 
Dr. and Mrs. Weinstein in a private transaction.  The purchase price was 
$.28568 per share, which Dr. Weinstein and his wife paid with their personal 
funds.  (These purchases were part of a stockholder restructuring in which 
Dr. Weinstein and his wife transferred 2,714,288 shares to the Issuer's 
treasury for cancellation.)

      Subsequently, Robert J. Weinstein, M.D. and Lois Weinstein conveyed 
1,400,000 shares of common stock to the W.F. Investments Enterprises Limited 
Partnership, a family partnership, and a 100,000 shares of Common Stock to 
the Robert and Lois Weinstein Family Foundation, Inc., a not-for-profit 
corporation, both of which are jointly controlled by Dr. and Mrs. Weinstein.  
Dr. and Mrs. Weinstein retain beneficial ownership of all 100,000 shares of 
stock held by the family foundation and all 1,400,000 shares held by the 
limited partnership.

      On or about June 30, 1998, both Walter Fisher, Ph.D. and Timothy 
Scott, Ph.D., conveyed 2,300,000 shares each of Photogen Technologies, Inc. 
common stock to the Fisher Family Investment Limited Partnership and the 
Scott Family Investment Limited Partnership, respectively.  Dr. Fisher and 
Dr. Scott each retain beneficial ownership of the shares held by their 
respective family partnerships.

Item 4.   PURPOSE OF TRANSACTION.

      The reporting persons filed their original Schedule 13D as a result 
of the Issuer's registration of its common stock under Section 12(g) of the 
Securities Exchange Act of 1934 pursuant to a Form 10-SB filed with the 
Securities and Exchange Commission.  All of the shares of Common Stock 
subject to this Schedule 13D have been owned by the reporting persons prior 
to the effectiveness of the Issuer's Section 12(g) registration.

      Mr. Smolik and Drs. Wachter, Dees, Fisher and Weinstein are officers 
and/or directors of the Issuer, and they are in a position to influence 
management of the Issuer.  In that capacity, they may consider from time to 
time various plans for the Issuer to raise additional capital which may have 
the effect of changing the present capitalization of the Issuer. 

       The shares of Common Stock beneficially owned by the reporting persons 
are subject to an Amended and Restated Voting Agreement and, accordingly, the 
parties to the Amended and Restated Voting Agreement may be deemed to share 
voting power with respect to their shares.  The reporting persons originally 
entered into a Voting Agreement dated May 16, 1997 (the "Original 
Agreement"), which was amended and replaced by the Amended and Restated 
Voting Agreement dated June 17, 1998 (the "Amended Agreement").  The Original 
Agreement was amended to reflect the increase in size of the Board of 
Directors from five to six and to remove Theodore Tannebaum, Stuart P. Levine 
and Thomas B. Rosenberg as parties.  The Amended and Restated Voting 
Agreement was entered into among Eric Wachter, Ph.D., Craig Dees, Ph.D., 
Walter Fisher, Ph.D., Tim Scott, Ph.D. and John Smolik (the "Tennessee 
Stockholders") and  Robert Weinstein, M.D. (the "Chicago Stockholder").  The 
Amended Agreement generally provides that the Tennessee Stockholders and 
Chicago Stockholder will vote shares of common stock beneficially owned by 
them (i) in accordance with the unanimous recommendation of the Board of 
Directors with respect to any amendments to the Articles of Incorporation or 
Bylaws, 

                                      -15-
<PAGE>

(ii) to fix the number of directors at six, (iii) to elect to the Board of 
Directors four persons nominated by holders of 80% of the shares of the 
Tennessee Stockholders and one person nominated by holders of 80% of the 
shares of the Chicago Stockholder (and to remove any such director at the 
request of the stockholders who nominated him), and (iv) to fix the number of 
directors on the Board's Executive Committee at three, two of whom will be 
selected by the Tennessee Stockholders and one of whom will be selected by 
the Chicago Stockholder.  The original Voting Agreement was amended effective 
as of June 17, 1998 and arrangements to finalize the amendment and other 
matters related to the amendment were completed on July 27, 1998.  The 
Amended Agreement is attached as Exhibit 1 to this Schedule 13D.

      Except as described above, no reporting person has any current plans or 
proposals that relate to or would result in:

a.    The acquisition by any person of additional securities of the Issuer, 
      or the disposition of securities of the Issuer;

b.    An extraordinary corporate transaction, such as a merger, reorganization 
      or liquidation, involving the Issuer or any of its subsidiaries;

c.    A sale or transfer of a material amount of assets of the Issuer or any of 
      its subsidiaries;

d.    Any change in the present board of directors or management of the Issuer,
      including any plans or proposals to change the number or term of directors
      or to fill any existing vacancies on the board;

e.    Any material change in the present capitalization or dividend policy of 
      the Issuer;

f.    Any other material change in the Issuer's business or corporate structure;

                                                               EXHIBIT 2

                        AMENDED AND RESTATED VOTING AGREEMENT

     This Amended and Restated Voting Agreement ("Agreement") is entered into 
as of the 17th day of June, 1998, by and among Eric A. Wachter, Ph.D. 
("Wachter"), Craig Dees, Ph.D. ("Dees"), Walter G. Fisher, Ph.D. ("Fisher"), 
Tim Scott, Ph.D. (individually and as General Partner of Scott Family 
Investment Limited Partnership, a Delaware limited partnership, "Scott"), 
John Smolik ("Smolik"), and Robert J. Weinstein, M.D. (individually, and as a 
General Partner of W.F. Investments Enterprises, Limited Partnership, a 
Georgia Limited partnership, "Weinstein") (individually, each a "Stockholder" 
and collectively the "Stockholders"), and joined into by Photogen 
Technologies, Inc. for purposes of Sections 1(c) and 1(d) herein.  Wachter, 
Dees, Fisher, Scott and Smolik are sometimes collectively referred to herein 
as the "Tennessee Stockholders;" Weinstein is sometimes referred to herein as 
the "Chicago Stockholder;" and the Chicago Stockholder or Tennessee 
Stockholders are each sometimes referred to herein as a "Stockholder." 

                                       RECITALS

     The Stockholders collectively own as of the date of this Agreement 
approximately 75% of the issued and outstanding shares of common stock, $.001 
par value per share (the "Common Stock"), of Photogen Technologies, Inc., a 
Nevada corporation (the "Company").  The Company owns all of the issued and 
outstanding shares of Photogen, Inc., a Tennessee corporation ("Subsidiary"). 
 

     The shares of Common Stock together with all other capital stock or 
securities of the Company, whether authorized or outstanding as of the date 
hereof or at any time hereafter, are collectively referred to as the "Shares."

     The Stockholders and Theodore Tannebaum ("Tannebaum"), Stuart P. Levine 
("Levine") and Thomas B. Rosenberg ("Rosenberg") were parties to that certain 
Voting Agreement dated May 16, 1997 (the "Original Agreement").  The parties 
desire to amend the Original Agreement to reflect an increase in the number 
of directors of the Company, to release the Shares of Tannebaum, Levine and 
Rosenberg from the provisions of this Agreement, and to restate the Original 
Agreement as set forth herein.

                                      AGREEMENT

     Now, therefore, in consideration of the mutual promises herein and other 
consideration, the receipt and adequacy of which is acknowledged, the parties
