This session focuses on advanced MRI techniques to characterize cerebrovascular hemodynamics and reactivity in stroke and cerebral arteriopathies. Presentations emphasize methodological innovations in BOLD, ASL, and angiographic imaging to improve assessment of vascular reserve, perfusion dynamics, and tissue viability.

		570-07-212. Hemodynamic delay correction in breath-hold BOLD fMRI critically alters cerebrovascular reactivity interpretation in stroke Rebecca Clements, Fatemeh Geranmayeh, Niamh Parkinson, Molly Bright Northwestern University, Chicago, United States of America Impact: Voxel-wise hemodynamic delay correction critically impacts CVR estimation in participants with stroke, particularly in brain regions with more extreme temporal offsets. Delay maps also aid physiological interpretation of CVR, helping distinguish vascular steal from impaired or collateral-dependent blood flow.
		570-07-213. Assessment of Cerebrovascular Reactivity Using Breath-Hold BOLD-fMRI in Moyamoya Disease Senmu Yao, Silu Chen, Liangliang Han, Bo Jiang, Yiwei Wang, Bing WU The Seventh Medical Center, Chinese PLA General Hospital, Beijing, China Impact: This breath-hold protocol enables widespread CVR assessment in China where intravenous acetazolamide is unavailable and MRI-compatible CO₂ delivery systems are nearly absent, providing clinicians an implementable tool for cerebrovascular reserve evaluation and surgical decision-making in Moyamoya disease.
		570-07-214. Pathological changes in LSA morphology and downstream basal ganglia perfusion in MCA stenosis patients at 5T Haocheng Sun, Mingyan Wu, Weihuan Fang, Jiawen Sun, Weiping Deng, Bin Liu, Naying He, Wenyan Kang, Jun Liu, Fuhua Yan, Xingfeng Shao Shanghai Jiao Tong University, Shanghai, China Impact: Findings highlight LSA stem and branch loss and caudate nuclei CBF reduction, supporting combined structural and perfusion assessment in patients with MCA stenosis.
		570-07-215. Hybrid multi-delay pseudo-continuous ASL for improved visualization of inflow dynamics and robust quantification Makoto Obara, Lena Vaclavu, Matthias van Osch, Osamu Togao, Koji Yamashita, Tatsuhiro Wada, Chiaki Tokunaga, Shota Ishida, Yu Ueda, Jihun Kwon, Masami Yoneyama, Marc Van Cauteren Philips Japan, Tokyo, Japan Impact: The optimized hybrid MD-pCASL demonstrated improved visualization of inflow hemodynamics with high SNR while maintaining high correlation with HYBRID-ISMRM in ATT and CBF, as predicted by the simulation results. This demonstrated its reliability and validity for clinical use.
		570-07-216. Improved TOF-MRA visibility using an advanced combination of deep learning and algorithm-based processing in moyamoya disease Noriyuki Fujima, Taro Fujiwara, Shotaro Fuchibe, Taro Igarashi, Joonsung Lee, Kohsuke Kudo Hokkaido University Hospital, Sappro, Japan Impact: The newly developed TOF-MRA technique, which integrates deep learning–based image reconstruction (DLR) with advanced computational background signal suppression, demonstrated significantly improved vessel visibility, particularly for small peripheral and collateral arteries, in patients with moyamoya disease.
		570-07-217. Image Quality Assessment of Periventricular Anastomoses Using DANTE T1-SPACE Yasutaka Fushimi, Sachi Okuchi, Akihiko Sakata, Takayuki Yamamoto, Satoshi Nakajima, Shuichi Ito, Masaki Umehana, Yongping Ma, Shin Morooka, Yusuke Utsunomiya, Akihiro Manabe, Yuta Urushibata, Alto Stemmer, Yuji Nakamoto Kyoto University Graduate School of Medicine, Kyoto, Japan Impact: Vessel-wall MRI using DANTE T1-SPACE with various image reconstruction was applied for moyamoya disease in this study, and Deep Resolve Gain achieved better parenchyma/vessel ratio and better signal-to-noise ratio for visualization of moyamoya vessels.
		570-07-218. Comparing performance of ultra-low field MRI with high-field MRI and CT to detect AIS and ICH Svenja Skadsem, Ayo Zahra, Aksel Leknes, Thomas Lindner, Ketil Oppedal, Soffien Ajmi, Martin Kurz, Muriel Bruchhage, Kathinka Kurz University of Stavanger, STAVANGER, Norway Impact: This study explores the use of ULF-MRI in patients with acute cerebral stroke. ULF-MRI could serve as a more accessible imaging tool for acute cerebral stroke aiming to treat patients earlier, potentially reducing morbidity and mortality on a global scale.
		570-07-219. Assessment of Tissue Viability in Hyper Acute Stroke with Sodium MRI Fernando Boada, Christian Licht, Azeezat Azeez, Georg Schramm, Jeremy Heit, Maarten Lansberg, Gregory Albers Stanford Medicine, Stanford, United States of America Impact: There is no image-based, quantitative, biomarker capable of identifying ischemic tissue destined to infarction in hyper acute stroke. Sodium MRI has the potential to fulfill this critical role, which could help improve outcome by reducing the risk of reperfusion injury.
