Future Virtual Meetings:
MR of Brain Physiology & Pathophysiology Study Group Virtual Meeting
Study Group Vision and Emerging MRI Techniques for Oxygen Extraction Fraction
Registration is FREE for members, US$50.00 for non-members.
Moderators: Zixuan Lin, Ph.D. & Lotte van der Voort, M.Sc.
This inaugural virtual meeting will introduce the mission and scope of the MR of Brain Physiology & Pathophysiology Study Group, outline its major scientific priorities, and invite input from the community regarding future educational, collaborative, and scientific activities.
The scientific focus of the meeting will be oxygen extraction fraction (OEF) MRI, an important physiological imaging biomarker that reflects the balance between cerebral oxygen delivery and utilization.
Two invited speakers will discuss current methodological approaches for measuring OEF with MRI, including their underlying principles, technical challenges, validation, and opportunities for standardization. The presentations will also highlight the clinical and translational potential of OEF MRI across a range of diseases.

ISMRT Virtual Meeting
NARS-fMRI: Neural Activity-Related Sodium fMRI for Functional Brain Mapping
Registration is FREE for members, US$25 for non-members.
Moderators: Jeff Chen, Grad.Dip. MRI, MRSO & Alexander Robertson, M.B.A., RT (MR), MRSO
Functional MRI has transformed human brain mapping by enabling noninvasive visualization of brain activity. Conventional high-resolution ¹H fMRI primarily relies on hemodynamic contrast, including changes in blood oxygenation, blood flow, and blood volume. While powerful, these vascular-based signals provide an indirect readout of neuronal activity and can be influenced by neurovascular coupling, vascular pathology, and regional differences in hemodynamic response. In this presentation, Xin Yu, Ph.D., will introduce neural activity-related sodium fMRI, or NARS-fMRI, as a new functional mapping approach designed to detect neural activity-associated ionic responses more directly. By leveraging sodium MRI to capture activity-related sodium dynamics, NARS-fMRI may provide a complementary or alternative benchmark to conventional BOLD-based mapping. Dr. Yu will discuss the technical rationale, preclinical validation, and translational potential of this method for future human brain mapping applications.

Imaging Neurofluids Study Group Virtual Meeting
Multimodal Approaches To Probe Neurofluids Dynamics and Brain Function
Registration is FREE for members, US$50 for non-members.
Moderator: Yicun Wang, Ph.D. & Li Zhao, Ph.D.
This seminar will feature cutting-edge methodologies used to measure fluid movement within the central nervous system, a crucial factor in maintaining cognitive health and understanding neurodegenerative diseases. Attendees will have the opportunity to hear from pioneering experts Jeffrey J. Iliff, Ph.D., and Tommi Väyrynen, M.Sc. who will present their latest research in the field. Dr. Iliff, well-known for his foundational work on the glymphatic system, and Tommi Väyrynen, an expert in advanced neuroimaging technologies, will demonstrate how combining diverse experimental and imaging modalities in neurofluids imaging.
