Abstract:

Perfusion reflects the activity of and vascular supply to tissue. It is an important physiological parameter that can provide diagnostic information for numerous brain disorders including brain tumors and stroke. There has been an increasing interest in developing methods for non-contrast perfusion imaging, because of the safety of nephrogenic systemic fibrosis patients and the repeated tests of functional studies. Arterial spin labeling (ASL) is a non-invasive perfusion technique with MRI. However, ASL inherently has low signal-to-noise ratio and is sensitive to off-resonance and flow velocity. Here, I will introduce latest techniques to improve the robustness and quantification of ASL MRI and a novel application on brain resting state network.

Li Zhao obtained his B.E. and M.E. from Tsinghua University and his Ph.D. from the University of Virginia in 2014. He is now a research fellow in Beth Israel Deaconess Medical Center and Harvard Medical School. His research is mainly focused on arterial spin labeling and its applications. He has received Summa Cum Laude Award and Magna Cum Laude Merit Awards from the International Society of Magnetic Resonance in Medicine (ISMRM), and authored a cover story of NeuroImage.​
