Last week MEDNAX, Inc. (NYSE: MD), which now brands itself as a national medical company, has kept a steady focus on its Pediatrix Medical Group and American Anesthesiology divisions for years. But last week marked its foray into radiology and telemedicine, with the $500 million acquisition of Virtual Radiologic Corporation (vRad). The deal adds a network of 350 radiologists, more than 75% percent of whom are subspecialty trained. They read and interpret more than five million diagnostic imaging studies annually, which are archived in vRad’s proprietary picture archive and communication system (PACS). MEDNAX gains radiology coverage in more than 2,100 healthcare facilities across all 50 states, and international markets. vRad’s current management team will remain with the company as part of MEDNAX, and don’t be surprised if more radiology groups come under their wing.
