We’re pleased to announce that St. Anthony's Arnold Diagnostic XR joined Mercy Clinic effective October 1, 2018. This is an exciting time for our organizations and for health care in the St. Louis area. All participating St. Anthony’s providers, co-workers and office locations will be integrated into Mercy to provide expanded services and better coordination of your care and wellness.

The best treatment comes from the best diagnosis. Our imaging center provides the latest technology and a trusted team. All tests are interpreted by a board-certified radiologist.
