Notes to Financial Statements
Subsequent Events [Text Block]	On October 10, 2012 we completed the refinancing of our senior secured credit facilities for an aggregate of $451.25 million. The refinancing includes a new credit agreement providing for a $350 million senior secured term loan and a $101.25 million senior secured revolving credit facility. See Note 1 for further details regarding this debt refinancing. On October 1, 2012 we acquired a 100% controlling interest in one of our non-consolidated joint venture imaging centers in which we previously held a 50% non-consolidated equity investment. As a result of this transaction, we began consolidating this imaging center, recording all of its assets and liabilities at their fair value at October 1, 2012. On October 29, 2012, Hurricane Sandy made landfall on the east coast of the United States bringing with it tropical storm force or hurricane winds and massive rains and flooding. This resulted in a negative impact to our operations in Maryland, Delaware, New York and New Jersey. We experienced site closures, loss of power and other related business disruptions. While our procedural volumes in our East Coast operations suffered as a result of the inability of patients to honor their scheduled appointments, the inability to schedule new appointments and the difficulties in patients getting to our locations as a result of dangerous travel conditions, we retain business interruption insurance to assist us in the mitigation of these circumstances. It is too early to estimate the extent of the financial impact of these events on our business.
