2019 Dr. Charles T. Dotter Lecturer

Alan H. Matsumoto, MD, FSIR


Over the past few decades, the U.S. health care system has seen steady decreases in efficiency, access, quality and various indicators of healthy lives, such as infant mortality, as compared to other developed nations. In addition, U.S. life expectancy has not only tapered off, but is starting to go down, according to Alan H. Matsumoto, MD, FSIR, who delivered this year’s Dr. Charles T. Dotter Lecture, “Patients and Patience: Why Interventional Radiologists Need Both,” on Sunday.

“Despite the fact that quality is lagging and our life expectancy is below other developed countries, the cost for U.S. health care continues to go up, such that it is averaging close to $12,000 per person per year,” Dr. Matsumoto said. “What that translates to is that the cost of health care in the U.S. is more than two times more than any other developed country, which totals about $3.3 trillion per year, or about 18 percent of our GDP. That is more than the entire GDP of the United Kingdom.”

Dr. Matsumoto is professor and chair of the department of radiology and medical imaging at the University of Virginia, Charlottesville, and an SIR past president. He believes that the U.S. health care system is currently being driven by a level of consumerism that has led to skyrocketing costs for patients, who are being increasingly “priced out” of quality health care.

2018 Dr. Charles T. Dotter Lecturer

Timothy P. Murphy, MD, FSIR

Beginning with the rendering of the first known arteriogram in 1896, the long road to the establishment of interventional radiology as the distinct specialty it is today was paved by a long list of pioneering and persistent visionaries, many of whom found themselves initially dismissed — often ridiculed — by the mainstream medical community. Indeed, the man known today as the “father of interventional radiology,” Dr. Charles T. Dotter, was no stranger to that treatment and found himself dubbed “Crazy Charlie” by some for his ideas, said SIR Past-president Timothy P. Murphy, MD, FSIR.

Dr. Murphy paid tribute to the pioneers of IR and the spirit of creativity and courage they all shared when he delivered the 34th Annual Dr. Charles T. Dotter Lecture, “Still Crazy After All These Years,” at SIR 2018.

Although it took the mainstream surgical community some time to understand angioplasty’s potential, famously quoted as one of the “greatest examples of collective stupidity ever,” Dr. Dotter’s ideas were eventually validated to the point that today most of the procedures that are done in surgery are referred to as “endo,” which Dr. Murphy said was “quite obviously a euphemism for interventional radiology.”

Dr. Murphy said that among the many lessons to be learned from the work of Dr. Dotter and others is that discovery isn’t always easy and is more often the result of determination and hard work rather than simple brilliance or intellect.

2017 Dr. Charles T. Dotter Lecturer

Michael D. Darcy, MD, FSIR

Changes in health care payment models that emphasize quality and results provide new opportunities for interventional radiologists, said Michael D. Darcy, M.D., FSIR, who delivered the Society of Interventional Radiology's (SIR's) 2017 Dr. Charles T. Dotter Lecture on March 5 during SIR's Annual Scientific Meeting in Washington.

Darcy, professor and chief of vascular and interventional radiology at the Mallinckrodt Institute of Radiology at Washington University in St. Louis, told his colleagues that the advent of the new IR Residency program provides a real opportunity to focus on mastery of interventional skills throughout a trainee's residency, not just in the fellowship year.

"In addition to being a great clinician and innovator, it is also critical to have superb technical proficiency," said Darcy. "As we move to an outcome-focused and team-based payment model, the ability of interventional radiologists to achieve better technical outcomes will be a clear differentiator for referring physicians."

The Dotter Lecture, supported by SIR Foundation, is an annual event named in honor of Dr. Charles T. Dotter considered universally to be the founding father of interventional radiology. The annual lecture spotlights an outstanding interventional radiologist who has greatly contributed to the field and to SIR.

"Dr. Darcy embodies the pioneering spirit of Charles Dotter and the spirit of the Dotter Lecture, which aims to inspire interventional radiologists to pursue excellence," said SIR President Charles E. Ray Jr., M.D., FSIR, professor and head of the department of radiology at the University of Illinois, Chicago.

Focused on education throughout his career, Darcy has trained over 125 interventional radiology fellows and continues to train new interventional radiology residents. Also, actively involved in research, he's participated in multiple clinical trials and authored or co-authored numerous papers and book chapters. Darcy is also a past-president of SIR and has been involved with the society for 30 years.
