Welcome to the Dotter Interventional Institute website. Established in 1990, the Dotter Institute is a multidisciplinary, free-standing clinical, research, and educational division within the Oregon Health & Science University (OHSU). This Institute is named in honor of Dr. Charles Dotter, a Radiologist who on January 14, 1964 initiated a paradigm shift in medicine when he performed the first percutaneous angioplasty. From this single innovation has grown Interventional Radiology, Interventional Cardiology, Endovascular Surgery, Interventional Neurosurgery, and many other specialties. More important, millions of patients have benefited from less invasive and often more effective image-guided interventions. I am honored to succeed Drs. Josef Rösch and Frederick Keller as the new Director of the Institute.

Within this website you will find information about the Institute, it’s faculty and staff, the many innovations that it has produced, and the numerous research and clinical programs, services, and activities that it supports. Hopefully, you will also be able to share in the excitement that we have for the present and future of image-guided interventions. We encourage you to explore this website, and better yet, contact or come visit us.
