Radiology CME Grand Rounds and Visiting Professors
We invite professors from around the country to speak at our institution to enhance our residents and local radiologists knowledge base. Our visiting lecturers can be viewed online via live streaming in case you are unable to join us in person. Our target audience for our lectures are OHSU local and Regional, Primary Care Physicians, Specialty Physicians, Physician Assistants and Nurse Practitioners. CME is available.
Oregon Health & Science University School of Medicine is accredited by the Accreditation Council for Continuing Medical Education to provide continuing medical education for physicians.
CreditIf you have any questions or would like to be a speaker please contact Katie Manoogian.
OHSU School of Medicine, Division of CME, designates this live activity for a maximum of 1 AMA PRA Category 1 CreditTM. Physicians should claim only the credit commensurate with the extent of their participation in the activity.

This CME Visiting Professor Lecture is Co-sponsored by Diagnostic Radiology and Oregon Radiological Society.
Nuclear magnetic resonance phenomena provide the basis for a rich set of methods for assessing anatomy and function in the living organism. The research objective of Richard L. Ehman, M.D., is to expand the range of tissue, organ and system characteristics that can be noninvasively evaluated with MRI techniques.
Dr. Ehman is best known for his groundbreaking work in medical imaging, specifically in nuclear magnetic resonance and its use in diagnosing a variety of conditions. He is also credited with developing magnetic resonance elastography, which allows physicians to determine the stiffness of internal organs without invasive procedures. His research program is focused on developing new imaging technologies.
Dr. Ehman holds more than 40 patents, and many of these inventions are widely used in medical care. His research has been supported by competitive grants from the National Cancer Institute, National Institute of Biomedical Imaging and Bioengineering, and the National Institute of Aging. Dr. Ehman is a prolific author, with over 600 published articles, books, book chapters, abstracts and commentaries.
- Medical imaging. Dr. Ehman's studies include investigation of new methods for high resolution MRI of moving structures, techniques of ultrafast MRI and methods for noninvasive mapping of the vascular system, especially the coronary arteries. Studies of the basic physics of motion effects in the magnetic resonance data acquisition process have led to the development of "navigator echo" imaging techniques that are highly suited for resolving structures that are in motion.
- Vascular flow. Other studies employ MRI to quantitatively assess vascular flow characteristics such as velocity, volumetric rates, and disordered flow or turbulence.
- MRI innovation. Additional research is directed at developing novel MRI techniques to probe bone trabecular morphology, to measure cellular organization in space and to noninvasively delineate the mechanical properties of the tissue. The objective of the latter project is to develop a technique for "palpation by imaging" to detect cancer and other tissue abnormalities at an early stage. Dr. Ehman's research employs MRI to directly image propagating acoustic waves in tissues, allowing images of viscoelastic properties to be generated.
