RADIOLOGY 100 | The Nation’s Private Radiology Practices Grow Up 35 to 49 FTE Radiologists 50 to 65 FTE Radiologists > 65 FTE Radiologists 15 15 100 83 12 12 77 71 9 8 7 6 6 5 30 31 29 30 4 2 2 2 radiologists. A hospital-based prac- tice, Advanced Radiology Services has no imaging centers, 113 FTE employ- ees and serves 14 hospitals. Southwest Diagnostic Imaging (SDI), Phoenix, Ariz., slipped from the third to the fourth position on the list, with 101 FTE radiologists, the same as last year, the same number of hospital clients, 15, and with roughly the same number of procedures: 1,821,680 versus 1,823,551 in 2014. The practice, however, grew in few other ways. SDI added three imaging centers for a total of 28, making it not only a leading provider of outpatient imag- ing services in the Phoenix Metro- politan Area, but tied with ProScan Imaging as a top private-practice pro- vider of outpatient imaging-center services. The practice also is the No. 1 employer among its peers with 851 employees, up from 752 last year. 20 Radiology Business Journal | October/November 2015 | RadiologyBusiness.com 2013 2010 2015 0 Figure 2.

University Radiology added 10 FTE radiologists for a total of 106 FTEs, leap-frogging from fifth on the list last year to become the second-largest prac- tice in the U.S. The group had 61 FTE radiologists when it first appeared on the list at number 14 in 2009, with eight imaging centers and 300 FTE employ- ees. It performed 1,242,000 studies. Bucking the divestiture trend, the practice continues to grow its imaging center assets, adding one center last year for a total of 16. University Radiol- ogy employs 474 FTE employees. Michigan-based Advanced Radiol- ogy Services, a veteran of the top five since we began conducting the sur- vey, occupies the No. 3 spot on the list this year with a total of 106 FTE 2 0 2010 2 2011 2 3 1 0 Figure 1.

Radia has grown steadily since 2008, when it debuted on the list at No. 9 with 65 radiologists. At the time, it operated four imaging centers but in 2015, the practice is down to two. The group’s 100 radiologists read 1,300,000 studies last year. Mergers and acquisitions For the first time since launching the annual survey, the median number of FTE radiologists increased in every practice-size cohort, but most signifi- cantly in the largest. The median num- ber of FTE radiologists increased from 82.9 to 85.5 in practices with more than 65 FTE radiologists; from 55.1 to 56.8 in the 50 to 65 cohort; from 37.8 to 40 in the 36 to 49 cohort; and from
