History

RadNet was founded in 1981 as a small imaging center in Los Angeles.^{[citation needed]}

In 1992 the company was bought by Primedex Health Systems, a California-based management company that catered to small medical clinics. Many of the company's new initiatives were centered around diagnostic imaging services, which were managed by RadNet. By the end of the 1990s, RadNet had replaced Primedex as the parent company, with many of Primedex's assets being folded into subsidiaries of RadNet.^[2][3]

In the early 2000s RadNet acquired smaller radiology firms.^[4] The company repurchased its debt in 2005 and in 2006 worked with General Electric to secure a $450 million syndicated loan with which to continue its corporate acquisitions.^[5] 2006 also saw RadNet and Primedex split their stock, resulting in RadNet becoming the official parent company and Primedex becoming a subsidiary.^{[citation needed]}

RadNet joined the S&P 600 in November 2019, replacing American newspaper provider Gannett Co.^[6]
