"This was really the first of its kind where we had individual physicians as part of these societies give answers locally, what IR service is like and what education is like in their place of practice and where they trained. This was really the first time we were able to get firsthand information ... It really is something we need to know so that we can target efforts as an IR community."—Justin Guan, MD

In this Journal of Vascular and Interventional Radiology (JVIR) audio episode, lead author Justin Guan, MD, speaks with journal Managing Editor Ana Lewis about his May 2025 paper "Results of a Global Survey on the State of Interventional Radiology 2024"

Not everyone in an underserved hospital is going to want to do all advanced procedures. And so fortunately, one of the things we have been able to do, as Dr. Ian Wilson coined, is we work where we're needed and live where we want to." -- J. Dana Dunleavy, MD

In this episode, host Ezana M. Azene, MD, PhD, speaks with J. Dana Dunleavy, MD, about the triumphs and tribulations of small and rural IR practices, particularly in the realm of spinal interventions.

"We had no tools. We just had to improvise. In a way, like you said, that was what made us think, 'How can I do this?' Because you had no tools, you had to think of ways to use what you had available to do procedures that otherwise you wouldn't have been able to do back then." —Wilfrido R. Castaneda-Zuniga, MD, FSIR, on innovation in early interventional radiology

In this episode, part of the ongoing celebration of the Society of Interventional Radiology (SIR) 50th anniversary, hosts Keith Horton, MD, FSIR, and Hector Ferral, MD, FSIR, speak with interventional radiology pioneer Wilfrido R. Castaneda-Zuniga, MD, FSIR, reflecting on lessons learned working with Kurt Amplatz, MD, FSIR, and others, stories of how their most seminal work came into being, the importance of peer mentorship, and more.
