Department and Faculty

Interventional radiology resident explaining a scan to a patient at Mayo Clinic in Rochester, Minnesota.

Mayo Clinic radiologists and staff provide the highest quality diagnostic and interventional imaging services in a caring and efficient manner, while sustaining outstanding programs in research and education.

The 115-year-old Department of Radiology — one of the first of its kind — is fully integrated with all the medical services available throughout Mayo Clinic. More than 180 radiologists and physicists cooperate with 1,300 support staff to provide diagnostic and therapeutic radiology services to patients.

Experts in all areas of radiology consult with specialists in other departments to "provide the best care to every patient every day." Radiologists work with state-of-the-art equipment, assisted by skilled technologists and nurses, to perform and interpret more than 1 million examinations yearly. This large number of cases, integrated with ongoing research and education, results in wide-ranging expertise in the imaging and treatment of diseases affecting patients of all ages.

From the program directorChad Fleming, M.D.

Welcome to the Interventional Radiology Integrated Residency Program. We utilize the integrated clinical, research, and educational practice at Mayo Clinic Rochester to train our residents to provide the most innovative, safest, and highest quality care through compassionate consultation, procedural intervention, and post-procedural care.  Each resident develops an increased awareness of quality patient care and clinical competence through immersion in a clinical practice dedicated to maintaining a multidisciplinary, team approach to build a trusting environment where the highest quality and most effective interventional therapies are taught, researched, and performed. 

The biggest strengths of our training program are the people and culture of Mayo Clinic. From the moment you begin training in our program, you are immersed in a collegial learning environment where leadership qualities are fostered. The Mayo Clinic Leadership Model promotes inspiring values, engaging colleagues, driving results, and thinking in a bold and forward way.  We seek and promote these qualities in our trainees as they are the interventional radiology leaders of the future.  Mayo Clinic’s core value that the needs of the patient come first is the foundation to all of our educational, clinic, and research endeavors imparted to all of our trainees.

I am incredibly proud to be a graduate of this program, and I am confident that you will say the same.

Facilities

The department has 30 clinical magnetic resonance (MR) scanners, including 16 3-Tesla magnets. The department has an additional three full-time dedicated research magnets. Additionally, there are 19 clinical computerized tomography (CT) scanners, including nine dual source scanners. An additional two CT scanners are dedicated to research. The department's equipment also includes 45 ultrasound machines, seven interventional suites and four neurointerventional suites.

The nuclear radiology practice includes 20 nuclear medicine cameras, two cardiac positron emission tomography (PET) scanners, five PET/CT scanners, one PET/MR scanner and two cyclotrons.

Faculty

In addition to caring for patients in their clinical practices, Mayo Clinic's faculty is committed to teaching and facilitating the growth of medical knowledge. Many faculty members have published and lectured extensively and are highly regarded in their fields.

Residents have direct access to radiology faculty throughout the training program.

Advisers and mentors

Residents are assigned dedicated faculty advisers who can provide comprehensive educational advice and personal support. Trainees meet with their advisers periodically throughout the residency to review progress and career goals, and ensure that their educational needs are being met. Advisers also serve as a contact point for introducing residents and their families to Rochester, Minnesota, and the Mayo Clinic system.

Visiting professors

Many prominent professors visit Mayo Clinic each year. They present their work during lectures, participate in hospital rounds and have informal discussions with trainees. Residents are encouraged to take full advantage of these educational opportunities.
