The ACGME-accredited Independent Vascular and Interventional Radiology (IR) Residency at Memorial Sloan Kettering Cancer (MSK) is dedicated to providing future interventional radiologists with complete IR training that encompasses the broad spectrum of IR, including but not limited to oncology, vascular care, palliative interventions, and pediatric procedures. At a time when many IR programs have lost much of their vascular procedures to turf battles, with specialties such as vascular surgery and cardiology adopting parts of traditional IR practice, including peripheral artery disease, MSK’s IR training uniquely provides vascular experience to trainees. Our IR residency boasts an extensive vascular program that comprises chronic and acute deep vein thrombosis, pulmonary embolisms, and peripheral arterial disease, including limb salvage.
Our residency program has trained many distinguished IR specialists who have entered private practice or academia and have gone on to become leaders and experts in the field. MSK’s academic programs and resources, tradition of clinical and scientific excellence, and high-quality procedures and subspecialty programs provide residents with a supportive and collaborative environment for clinical learning and scholarship. In addition to offering unparalleled oncologic training administered by world experts, MSK has taken a conscientious and proactive approach to providing the most holistic IR training program around.
Mission Statement
The IR residency program prepares residents for a successful career in IR by teaching them:
- The role of image-guided interventions
- The multidisciplinary options to perform image-guided interventions independently
- How to use clinical skills to support the establishment of an effective, patient-centered private, academic, inpatient, or outpatient IR practice. Providing thoughtful and compassionate professional care as a clinician and in support of colleagues.
Program Aims
- Create an environment for IR residents to gain proficiency in the independent performance of image-guided interventions by leveraging dedicated support from leadership, attendings, practice extenders, ancillary staff, and institutional and departmental facilities and resources.
- Promote lifelong learning to understand the role of image-guided interventions, multidisciplinary options, and effective clinical management of patients through didactic lectures, conferences, morning rounds, self-guided learning, and patient care.
- Train IR residents on thoughtful and compassionate patient-centered inpatient and outpatient clinical care by requiring patient ownership, evaluation, and management.
- Cultivate a desire for quality research- and evidence-based practice by securing protected time away from procedure rooms to recuperate, learn, and conduct research.
- Encourage professionalism and productive interpersonal and communication skills.
Yolanda Bryce, MD, RPVI – IR Residency Program Director
Yolanda Bryce, MD, RPVI joined Memorial Sloan Kettering Cancer Center in 2016 and is an Assistant Attending Radiologist at Memorial Hospital and an Assistant Professor in the Weill Cornell Medical College. She specializes in vascular disease in oncologic patients and is board-certified through the American Board of Vascular Medicine and holding a Registered Physician Vascular Interpretation (RPVI) certification. In 2018, Dr. Bryce became the founding director of MSK’s Noninvasive Vascular Imaging Center (Vascular Lab) and started the institution’s Peripheral Arterial Disease (PAD) program, which seeks to improve the mobility and quality of life of some of the most vulnerable patients — those with both cancer and life-limiting PAD. Given her dual training in breast imaging and interventional radiology, Dr. Bryce probes the intersection of these subspecialties, pioneering minimally invasive cryoablation techniques to treat locoregional disease in patients who are poor candidates for surgery. She also co-leads the metastatic breast cancer interventional oncology program at MSK, which provides treatment to breast cancer survivors with oligometastases, oligoprogression, and those needing salvage interventions.
Dr. Bryce earned her medical degree from Loma Linda University School of Medicine in 2009 and completed a residency in Diagnostic Radiology at Mount Auburn Hospital in Cambridge, Massachusetts in 2014, followed by subspecialty training in Breast Imaging at MSK in 2015, and finally, a fellowship in Vascular and Interventional Radiology at the world-renowned Miami Cardiac and Vascular Institute in 2016. She is a sought-after speaker in her niches of peripheral arterial disease in patients with cancer, as well as interventional oncology (IO) interventions in primary and metastatic breast cancer and serves as the principal investigator of prospective studies within these fields. She accepted the program directorship of the IR Residency and IO Fellowship programs at MSK in January 2020 and has since revamped their infrastructure and vision.

Adrian J. Gonzalez-Aguirre, MD – IR Residency Associate Program Director
Adrian J. Gonzalez-Aguirre joined Memorial Sloan Kettering Cancer Center (MSK) in 2014 as an interventional oncology fellow and later became an assistant attending radiologist at Memorial Hospital and an assistant professor at Weill Cornell Medical College. Before coming to MSK, Dr. Gonzalez-Aguirre was an interventional radiologist (IR) at top academic centers in Mexico and has been closely involved in the training of IR specialists since 2011. In 2012, he joined the National Cancer Institute in Mexico as the first IR and was responsible for formally starting its IR clinical and training program. He specializes in the treatment of liver metastasis, specifically in neuroendocrine tumors. At the same time, he works closely with the pediatric team at MSK in an effort to offer minimally invasive diagnostic and therapeutic procedures for pediatric cancer.
Dr. Gonzalez-Aguirre earned his MD from the Universidad Autónoma de Ciudad Juárez. He subsequently joined the Radiology Residence at Instituto Nacional de Ciencias Médicas y Nutrición “Salvador Zubiran”(INCMNSZ), where he did his IR fellowship. Together with Dr. Bryce, Dr. Gonzalez-Aguirre works to provide the interventional radiology and interventional oncology training programs with support to fulfill MSK’s mission of training the next generation of leaders in these areas.
Program Description
IR residents choose the procedure rooms that best align with their learning journey on a daily basis. Room selection is based on a rotating hierarchy picking system; on the first day of the week, the resident has the first pick of rooms; on the second day, they have the second pick; on the third day they have the third pick, and so on and so forth. Daily choice options include three hybrid rooms (soon to be five) as well as an advanced standalone fluoro suite and a positron emission tomography (PET) procedural suite at the Main Hospital, three hybrid rooms and a PET procedural suite at the Koch Center, and the American Endovascular Office-Based Lab (OBL) in Harlem, New York, with Dr. Joseph Shams and Dr. Noam Spinowitz. Residents see patients before their respective procedures and follow the patients through sign off, establishing patient ownership and care.
IR residents also regularly take part in the IR clinic, where they see patients both virtually and in person, and read for the Vascular Lab, which prepares residents to sit for the Registered Physician in Vascular Interpretation (RPVI) exam. Residents enjoy a post-call, out-of-rooms day for research and investments in well-being. They typically complete at least one research project to present at meetings and produce author papers. In addition, there is a two-month rotation at NewYork-Presbyterian/Weill Cornell, where there are additional opportunities experience with consultation and non-oncologic interventions.

Residents on the IR Program
“The training program at MSK provides a great deal of autonomy and is particularly robust in advanced vascular and oncologic interventions. Additionally, our rotations at Cornell and several office-based labs through American Endovascular provide us with broad training in various practice settings. As a result, I feel well-prepared across the gamut of IR procedures. Additionally, due to the diverse and accomplished faculty, trainees have excellent mentors, which enable clinical and career advancement.”
—Akshaar Brahmbhatt, MD, Independent IR Track
“Since day one at MSK, I’ve felt welcomed and supported by amazing people who are dedicated to their patients, knowledgeable, and always working as a team. Everyone loves to share their knowledge and at the same time, gives you enough autonomy, which is so important during the last year of training. The variety of the procedures we perform daily, experience in the clinic or outpatient PAD [Peripheral Arterial Disease] center, multidisciplinary conferences, and research work altogether give me great confidence that I am well-prepared to become an independent interventional radiologist.”
