Explanation of Responses:

*	If the form is filed by more than one reporting person, see Instruction 4(b)(v).
**	Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1)	This option became exercisable as to 10,000 shares upon optionee's completion of one year of service as a director on June 10, 2003, and thereafter became exercisable as to 833 shares per month for 24 months.
(2)	This option becomes exercisable as to 30,000 shares upon optionee's completion of one year of service as Chairman of the Board on December 3, 2003, and thereafter as to 833 shares per month for 24 months.
(3)	The derivative securities included in the table are restricted stock units (RSUs) that are granted to independent directors automatically each year under the Radiologix, Inc. 2004 Long-Term Incentive Compensation Plan (LTICP). RSUs are scheduled to vest in full on the one year anniversary of the grant date, but at that time they will convert automatically into deferred stock units (DSUs). They will remain deferred until one year after the reporting person's retirement, resignation, or termination from Board service, or a change in control of Radiologix, as defined in the 2004 LTICP. DSUs do not have an expiration date. Unvested RSUs are subject to forfeiture if the reporting person ceases to serve on the Board of Directors at any time during the year following the grant date.
Remarks: This amendment is being filed to correct typographical errors in the date exercisable of the RSU granted June 2, 2005.

Note: File three copies of this Form, one of which must be manually signed. If space is insufficient, see Instruction 6 for procedure.
