Some career paths are meticulously planned, while others emerge from life’s unexpected turns. For Dr. Franco Orsi, a leading figure in interventional radiology, the journey into his field was born from a deeply personal experience—one that shaped both his professional trajectory and his dedication to pushing the boundaries of minimally invasive medicine.
Today, he serves as the Chief of the Clinical Department of Interventional Radiology at the European Institute of Oncology (IEO) in Milan, a role he has held since 2015. Over the years, he has pioneered advancements in interventional oncology, performing thousands of procedures and mentoring generations of physicians in the ever-evolving world of image-guided therapies.
In February 1985, at the age of 21, Franco Orsi was a second-year medical student when his life took an unexpected and dramatic turn. A severe car accident left him critically injured and fighting for survival through months of hospitalization. He endured multiple complications—severe respiratory failure, a medically induced coma, and even a cardiac arrest. At one point, he was administered the last rites.
During his hospitalization, doctors suspected a pulmonary embolism and performed a pulmonary angiogram—a procedure that would unknowingly set the course of his career. Seeing the angiographic images of his own lungs sparked an unexpected fascination. As he gradually recovered over the following year, he found himself deeply intrigued by the medical specialty that had played a role in his diagnosis and care.
Once back in his medical studies, he sought to understand who performed such procedures and how they were done. He soon discovered the world of interventional radiology—a field still in its early stages at the time. Driven by curiosity and ambition, he approached the Institute of Radiology at Sapienza University in Rome, where he was fortunate to meet Prof. Plinio Rossi, a visionary who had just returned from the United States. This mentorship ignited his journey into IR, shaping a future that would become instrumental in advancing the field.
After obtaining his MD with honours from Sapienza University in Rome, Dr. Orsi specialized in diagnostic and interventional radiology. His thirst for knowledge led him abroad, where he trained at some of the world’s leading institutions, including the Royal Postgraduate Medical School in London, the Armed Forces Institute of Pathology in Washington D.C., and Massachusetts General Hospital in Boston.
In 1994, a pivotal moment in his career arrived when the legendary Prof. Umberto Veronesi, one of the most influential figures in modern oncology, invited him to join the newly established European Institute of Oncology in Milan. Here, he played a fundamental role in developing interventional oncology, helping to cement these disciplines as critical pillars of modern cancer treatment.
Over the years, Dr. Orsi has performed thousands of procedures, including:
- 1,500+ vascular interventions (TACE, TAE, HIAC, SIRT, PHP, UFE)
- 2,000+ percutaneous, laparoscopic, and open surgical ablations (liver, lung, kidney, bone, adrenal, thyroid…)
- 400+ high-intensity focused ultrasound (HIFU) treatments
- 4,000+ image-guided biopsies
His expertise spans both research and clinical practice, with a commitment to integrating cutting-edge technology into minimally invasive therapies.
Beyond his clinical work, Dr. Orsi has been instrumental in shaping international standards and education in interventional oncology. He has held leadership roles in key organizations, including:
- CIRSE Fellow
- Scientific Program Committee member of ECIO
- Board President of SIO
- Past-President of IESIR and ISMINIM
- Assessor for IASIOS
- Advisory Board member of INTERACT-Europe 100 project
As an educator and mentor, he has been a speaker at over 500 international congresses and has authored more than 100 peer-reviewed publications. His contributions have shaped clinical guidelines and best practices worldwide.
Dr. Orsi’s journey from a critically injured patient to a world leader in interventional radiology is a testament to resilience, curiosity, and an unyielding passion for medical innovation. His experience underscores the transformative power of IR—not only for patients but also for those who dedicate their lives to its advancement.
As he prepares to deliver the Andreas Grüntzig Lecture at CIRSE 2025 in Barcelona, his story serves as an inspiration for the next generation of interventionalists. It is a reminder that sometimes, the most profound professional callings emerge from life’s most unexpected moments.
Josef Roesch Lecturer 2025 | Dr. Yuji Okuno
Since its introduction in 2003, the Josef Roesch Lecture has been given by a number of prominent interventional radiologists who have taken this opportunity to reflect on the statues of interventional radiology and its various treatments.

Dr. Yuji Okuno is an interventional radiologist specializing in embolization treatments for pain management. Raised in Japan by a father who was a creative interventional oncologist and a mother who was a visionary psychiatrist, he grew up with a strong drive to innovate rather than follow medical trends. From an early age, he was encouraged to explore new ideas and develop treatments that had never been done before. His exposure to psychology through his family also shaped his patient-centred approach, particularly in understanding the psychological factors influencing pain.
During medical school, a solo trip to Bangladesh deepened his awareness of healthcare accessibility and the economic challenges of medical treatment. This experience fuelled his commitment to developing cost-effective and widely available therapies. Initially pursuing interventional oncology, he was inspired by his father’s work and observed that rheumatoid arthritis patients undergoing angiography exhibited abnormal blood vessel patterns. This led him to explore embolization as a novel approach to treating joint pain.
To strengthen his research foundation, Dr. Okuno studied vascular pathology at Keio University, where he investigated the microscopic structure of abnormal blood vessels. In 2012, he initiated a clinical study that later resulted in groundbreaking publications, demonstrating the effectiveness of embolization for joint pain. Recognizing the high costs and complexity of traditional interventional radiology, he sought to make treatments more accessible. By refining techniques, utilizing smaller 3Fr catheters, and streamlining procedures, he developed a minimally invasive, outpatient-based model—bringing IR closer to everyday medical practice, much like dentistry.
In 2017, he established Okuno Clinic, an independent medical practice dedicated to embolization treatments. Since then, he has expanded to 10 clinics across Japan, offering innovative pain management solutions to thousands of patients. His contributions to the field have been widely recognized, and in 2023, he was honoured with the CIRSE Award of Excellence and Innovation in IR, acknowledging his pioneering work and dedication to advancing interventional radiology.
Beyond embolization, Dr. Okuno has continued to develop new interventional techniques. Following the success of TAME (transcatheter arterial micro-embolization), he introduced DOCHU (direct arterial injection therapy), a simplified catheter-based treatment designed to further improve accessibility and efficiency. These advancements have revolutionized minimally invasive procedures, and his team now performs over 5,000 procedures annually.
Though his approach was initially uncharted, it gained recognition, and by 2016, other physicians began adopting similar techniques. Committed to the democratization of medical knowledge, Dr. Okuno actively contributes through academic publications, online content, books, and media appearances. He also founded the VENTI conference, an international platform dedicated to ensuring the safe and effective implementation of embolization treatments worldwide.
Dr. Okuno continues to push the boundaries of interventional radiology, expanding applications beyond musculoskeletal conditions to include areas such as chronic prostatitis. Through ongoing research, innovation, and education, he remains dedicated to improving patient care and making cutting-edge treatments widely available.
