About the Interventional Radiology (IR) Clinic

The Interventional Radiology (IR) Clinic is part of Eastern Radiological Associates and is led by Dr. Brian Christenson, an interventional radiologist. Procedures are performed using advanced, minimally invasive techniques in the state-of-the-art Interventional Radiology Suite at St. Vincent Regional Hospital in Billings, Montana.

Most patients are referred to the IR Clinic by their oncologist, nephrologist, primary care provider, or another treating healthcare professional. While self-referrals are welcome, a referral from your healthcare provider often helps expedite the process by ensuring we have the medical records and imaging needed to evaluate your condition.

We work closely with you and your other physicians to provide the services to you.
