Annual Oration in Diagnostic Radiology Presented Today

Tuesday, Dec. 01, 2015

Three categories of innovation will shape the future of radiology: imaging technologies, infrastructure and information/communications systems, and the application of the imaging correlates of precision medicine, according to James H. Thrall, M.D., who will present today's Annual Oration in Diagnostic Radiology, "Trends and Developments Shaping the Future of Radiology."

On the horizon, X-ray based imaging will reduce radiation exposure to the point that dose will no longer be a topic of concern or controversy, and phase contrast imaging with X-rays—which has the potential to reduce radiation doses by 10- to 100-fold or more—is likely to be the next entirely new imaging method in clinical practice. Data will drive development of better appropriateness criteria, which will be immediately available to ordering providers and their patients, Dr. Thrall says. And radiology will play a critical role in precision medicine by establishing links between patient genotype and imaging phenotypes for surveillance of disease manifestation, assessment of disease extent and discovery of genetic polymorphisms.

But the future holds challenges for the specialty as well. New developments will lead to vastly increased complexity in radiology practice with associated increased educational requirements, especially in parametric imaging. And radiology will face an unremitting competition for "ownership" of imaging methods between specialties in clinical practice and in research, Dr. Thrall says.

Dr. Thrall is Chairman Emeritus of the Department of Radiology at Massachusetts General Hospital, Boston. Dr. Thrall served as Chairman of the Department of Radiology at Massachusetts General Hospital from 1988 until 2013 while holding the Juan M. Taveras Professorship of Radiology at Harvard Medical School.

Question of the Day:

I want to change the MR imaging parameters for a new protocol based on a research paper I read, but the console says the SAR is too high. What is SAR?

Tip of the day:

Patients who have many follow-up head CTs should be assessed for dose to the eyes as they swiftly become at risk for cataracts.
