Summary

Xiufeng Li, Ph.D., is an Assistant Professor at the Center for Magnetic Resonance Research (CMRR), Department of Radiology, at the University of Minnesota. Dr. Li received his Bachelor of Science in Mechanical & Manufacturing Engineering (1992) and Master of Science in Computer Aided Designed (CAD) and Computer Aided Manufacturing (CAM) (1995) from Beijing Unniversity of Aeronautics and Astronautics (BUAA). Dr. Li’s Ph.D. research work was conducted under the mentorship of Dr. Richard R. Briggs with the focus on MRI physics and Neuroimaging (2003-2009), and continued after his graduation as a Senior Research Scientist (2009-2010) at the University of Texas Southwestern Medical Center at Dallas. Dr. Li joined CMRR as a research associate, and then works as an Assistant Professor to contribute his expertise and experience for applying ASL methods in the brain and the body at both 3T and 7T (2010-present).

Dr. Li's research focuses on the development and optimization of non-contrast enhanced (NCE) perfusion MRI technique-arterial spin labeling (ASL), as well as other MRI approaches (e.g. NCE angiography, T1 and T2 relaxometry) at both 3T and 7T, and on the application of these techniques to understand organ function and pathophysiology of diverse diseases, e.g. Gulf War Illness, Stroke, Prostate Cancer, Chronic Kidney Disease, and Cardiovascular Disease.

Research

Research Summary/Interests

  • Development and optimization of non-contrast enhanced perfusion imaging technique, arterial spin labeling (ASL), at 3T and 7T in both the brain and the abdominal organs, e.g. the prostate, kidneys and the heart
  • Customizing and utilizing novel techniques for ASL imaging: multiband EPI (MB-EPI), dynamical B1 shimming, multi-channel transmit/receiving coils, etc.
  • Application of ASL imaging methods, as well as other imaging modalities (NCE angiography, diffusion-weighted imaging, T1 and T2 relaxometry, etc.), to clinical studies with the ultimate goal to improve healthcare
