Equity Method Investments and Joint Ventures [Abstract]

INVESTMENT IN JOINT VENTURES

We have ten unconsolidated joint ventures with ownership interests ranging from 35% to 50%. These joint ventures represent partnerships with hospitals, health systems or radiology practices and were formed for the purpose of owning and operating diagnostic imaging centers. Professional services at the joint venture diagnostic imaging centers are performed by contracted radiology practices or a radiology practice that participates in the joint venture. Our investment in these joint ventures is accounted for under the equity method.   

The following table is a roll forward of our investment in joint ventures during the three months ended March 31, 2015 (in thousands):

Balance as of December 31, 2014	$	32,123
Equity in earnings in these joint ventures		1,102
Distribution of earnings		(3,041	)
Balance as of March 31, 2015	$	30,184

We earned management service fees from the centers underlying these joint ventures of approximately $2.4 million in each of the three months ended March 31, 2015 and 2014, respectively. At the end of the period we eliminate from total fees recorded the uncollected portion of these fees that are associated with our ownership interests and offset this with an increase to our equity earnings.
