What we do

Our mission is simple. Eastern Radiological Associates serves the patient and physician community of the region (Montana, Wyoming, and surrounding) by providing the highest quality diagnostic imaging and interventional services in a caring and compassionate atmosphere.

The Interventional Radiology Clinic (IR Clinic) is operated by Dr. Christensen as part of Eastern Radiological Associates. The IR Clinic is independent, but all state-of-the-art procedures are performed in specialized areas at St. Vincent Healthcare. Most patients are referred to the IR clinic by oncologists, nephrologists, or other treating physicians and professionals, however, patients may also be self-referred.
