Richard L. Ehman, M.D., RSNA Board of Directors Liaison for Science, is a professor of radiology at the Mayo Clinic in Rochester, Minn., and clinician-investigator in Mayo’s Center for Advanced Imaging Research. Dr. Ehman also holds joint appointments in physiology and biomedical engineering. He has been with Mayo since 1984 and currently serves on the Mayo Clinic Board of Governors.
“For me, the RSNA represents radiology in full force,” Dr. Ehman said. “By truly reflecting the breadth and depth of radiology, RSNA has an essential role in helping to define the future of medical imaging.”
Dr. Ehman’s research has focused on developing new MRI-based technology. He is the inventor of MR elastography, a modality that is being used as a non-invasive alternative to liver biopsy for detecting hepatic fibrosis. Dr. Ehman is also credited with developing several other technologies that are widely used in clinical MRI, such as spatial presaturation used to reduce flow artifacts and “navigator echo” imaging techniques used to resolve structures in motion.
As principal investigator on multiple National Institutes of Health (NIH) R01 grants over the last two decades, Dr. Ehman has served as a referee on NIH study sections and chaired the Medical Imaging (MEDI) study section from 2002 to 2004. He has served on the National Advisory Council of the National Institute of Biomedical Imaging and Bioengineering and on the Council of Councils of the National Institutes of Health.
Dr. Ehman holds more than 30 U.S. and foreign patents for his inventions and has authored more than 200 publications. Funding for one of his first research grants, “Development of a Comprehensive Method for High Resolution Magnetic Resonance Imaging of Moving Structures,” came from the RSNA Research & Education (R&E) Foundation. Dr. Ehman now serves on the R&E Board of Trustees. RSNA honored Dr. Ehman with its Outstanding Researcher award in 2006.
“The RSNA has shown a deep commitment to advancing the science and technology of medical imaging through its extensive scientific programming at its annual meeting, through its advocacy for federal funding for imaging research and through the phenomenally successful research grant program of the Research and Education Foundation,” Dr. Ehman said.
Dr. Ehman earned his bachelor’s and medical doctor degrees from the University of Saskatchewan, which awarded him an honorary doctorate in 2000. He completed his radiology residency at University of Calgary and a fellowship at the University of California San Francisco before joining the staff of the Mayo Clinic. During his career he has mentored more than 30 graduate students and fellows.
Dr. Ehman was 2002-2003 president of the International Society for Magnetic Resonance in Medicine (ISMRM), from which he received the gold medal in 1995. He served as president of the Academy of Radiology Research from 2011 to 2013 and is the current president of the Society of Body Computed Tomography and Magnetic Resonance Imaging (SCBTMR). He is a fellow of the Society for Magnetic Resonance Imaging and the American College of Radiology. Dr. Ehman was elected to the Institute of Medicine of the National Academies of Science in October 2010.
