The capability to image temperature is a very attractive feature of MRI and has been actively exploited for guiding minimally-invasive thermal therapies. In this talk, different MR-based temperature-sensitive approaches for temperature measurement will be introduced. Among these approaches, proton resonance frequency (PRF) thermometry provides the advantage of excellent linearity of signal with temperature over a large temperature range, so has evolved into the most widely used MR-based thermometry method. After the review of the basic principles of PRF-based temperature mapping, technical advancements aimed at increasing the imaging speed and/or temperature accuracy of PRF-based thermometry pulse sequences will be discussed. Clinical applications in MR-guided thermotherapy by using PRF-based temperature measurement will also be introduced.


Jing Yuan graduated from Department of Electronic Engineering of Tsinghua University, Beijing as bachelor and master in 2000 and 2002, respectively. He received Ph.D. in 2006 in the Department of Electrical and Electronic Engineering from the University of Hong Kong. From 2007 to 2008, he was a postdoctoral research fellow in the department of radiology at Brigham and Women's Hospital, Harvard Medical School, USA. He later joined the Chinese University of Hong Kong as an assistant professor for the Department of Imaging and Interventional Radiology in 2009. Dr. Yuan is a full member of IEEE and ISMRM (International Society for Magnetic Resonance in Medicine), serves as the editorial board member in the journal of "Quantitative Imaging in Medicine and Surgery" and is a reviewer for several international journals. He has published over 30 international journal papers and over 50 ISMRM conference abstracts.
