Skill Level: Intermediate

		369-04-001. Quantitative Analysis of Vascular Characteristics in Post-Mortem Human Midbrain T2w MRI Marshall Xu, Kevin Sitek, Omer Faruk Gulban, Saskia Bollmann The University of Queesland, Brisbane, Australia Impact:* We used a deep-learning–driven framework to map midbrain vasculature with high-resolution post-mortem MRI. The approach enables detailed geometric and topological analysis, offering new opportunities to investigate subcortical hemodynamic and vascular contributions to human brain metabolism.
		369-04-002. Denoising High Resolution Intracranial Vessel Wall Imaging at 7T Tudor Sava, Rebecca Glarin, Bahman Tahayori, Warda Syeda, Yasmin Blunck, Bradford Moffat, Leigh Johnston University of Melbourne, Melbourne, Australia Impact: We found that applying state of the art open source denoising to a clinically feasible acquisition yields image quality comparable to an acquisition time that is eight times longer. We applied this to intracranial vessel wall imaging at 7T.
		369-04-003. Longitudinal Hemodynamics of STA-MCA Bypass a Comparative Study of TCD and 4D Flow MRI with Dual Post-Processing Platforms Yuting Wang, Mingfang Luo, Zhenyu Wang, Xiao Hu, Meining Chen, Wei Sheng Sichuan Provincial People’s Hospital, University of Electronic Science and Technology of China, Chengdu, China Impact: This study highlights the complementary role of TCD and 4D Flow MRI and supports the interchangeability of 4D Flow MRI post-processing tools. Additionally, bypass hemodynamic may relate to infarction risk, warranting careful interpretation and further investigation.

		369-04-005. Assessing physiological variability in carotid pulse wave velocity and arrival time using phase contrast MRI Benjamin Keedwell, Aaron Hess, Thomas Okell, Iulius Dragonu, Yang Ji, Peter Jezzard Centre for Integrative Neuroimaging, FMRIB Division, Nuffield Department of Clinical Neurosciences, University of Oxford, Oxford, United Kingdom Impact: Repeatable phase contrast MRI measurements of pulse wave velocity are achievable through a simultaneous multi-slice acquisition. Sequence design should account for physiological variability in pulse arrival time across multiple timescales to ensure accurate and precise measurements.
		369-04-006. Multi-center scan-rescan reproducibility of fast quantitative MRI of carotid atherosclerosis Dimitris Mitsouras, Deniz Karakay, Seong-Eun Kim, Meng Lu, Jonas Schollenberger, Arunbalaji Pugazhendhi, Sheila Martinez, Alex Gill, Kevin Johnson, Herman Morris, J. Rock Hadley, Yibin Xie, Vibhas Deshpande, David Saloner, Debiao Li, Gerald Treiman, Craig Weinkauf, Maria Altbach, J. Kevin DeMarco, Scott McNally, Dennis Parker University of California San Francisco, San Francisco, United States of America Impact: We establish the scan-rescan reproducibility of fast quantitative T1, T2 and ADC measurements of carotid plaque atheromatous components in a real-world multi-center setting, providing key figures-of-merit needed for future trial design.
		369-04-007. Feasibility and Contrast Sensitivity of T1ρ and R1ρ dispersion of carotid artery at 3T Ning Xu, Ayda Arami, Milo Commandeur, Martina Savic, Niccolo Voster, Christal van de Steeg-Henzen, Xihai Zhao, Sebastian Weingärtner Tsinghua University, Beijing, China Impact: Susceptibility changes of RBCs during early stage IPH affect spin-lock measurements at low FSL. A black blood prepared carotid artery R1ρ-dispersion sequence can be used to measure these parameters in vivo.
		369-04-008. Optimization of Spatial Resolution for Intracranial Vessel Wall Imaging on a 5.0T MRI System Lei Zhang, Yihang Zhou, Ran Yang, Lixin Du, Pan Wang, Dong Liang, Ye Li, Xin Liu Paul C. Lauterbur Research Center for Biomedical Imaging, Shenzhen Institute of Advanced Technology, Chinese Academy of Sciences, Shenzhen, China Impact: This study identifies the optimal resolution for intracranial vessel wall imaging on a 5T MRI system, enabling faster, more accurate detection of vascular lesions and improved diagnostic reliability in cerebrovascular diseases, while guiding protocol optimization for future ultra–high-field clinical applications.
		369-04-009. Whole-brain 4D MRA with improved visualization of distal arteries using multiple-overlapping thin slab acquisition Tianrui Zhao, Ziyi Huang, Jianing Tang, Lirong Yan Northwestern University, Chicago, United States of America Impact: The proposed MOTSA 4D MRA technique enables whole-brain coverage, complete flow dynamic visualization, and fine vessel delineation with high spatiotemporal resolution, providing a powerful non-contrast imaging tool for cerebrovascular research and clinical applications.
		369-04-010. Accelerating Acquisition Time of 3D TOF-MR Angiogram Data Using Super-Resolution Convolutional Neural Networks Abel Tessema, HyungJoon Cho Ulsan National Institute of Science and Technology, Ulsan, Korea, Republic of Impact: This study demonstrates that optimized CNN-based super-resolution can reconstruct over 88% of vascular structures while potentially reducing 3D TOF-MRA acquisition time by 16×, enabling faster, high-quality, and artifact-minimized angiographic imaging to enhance diagnostic accuracy and clinical applicability.
