16:00		607-03-001. Mesoscopic Diffusion-Weighted Imaging via Multi-Shot Spirals on a High-Performance Gradient System Paul Dubovan, Xingwang Yong, Yohan Jun, Yuting Chen, Gabriel Ramos Llordén, Susie Huang, Berkin Bilgic Athinoula A. Martinos Center for Biomedical Imaging, Massachusetts General Hospital and Harvard Medical School, Charlestown, United States of America Impact: Advancing the acquisition of high-quality diffusion data in the mesoscopic regime enhances data fidelity and enables finer feature distinction, increasing the precision of localized analyses essential for improved understanding, diagnosis, and treatment of disease.
16:11		607-03-002. General Flexible Fully Self-gated Phase-contrast MRI with Independent Projection Acquisition (IPA) Wenjian Liu, Wenchao Yang, Zijian Zhou, Peng Hu ShanghaiTech University, Shanghai, China Impact: The general self-gating technique enables robust, hardware-free flow quantification in any imaging plane across multiple body regions. It simplifies complex scans, eliminates external devices, and makes versatile cardiovascular MRI more accessible for routine clinical use and research.
16:22		607-03-003. Fast design of safe spirals on the scanner David Leitão, Sarah McElroy, Daniel West, Jo Hajnal, Tobias Wood, Tomoki Arichi, Shaihan Malik King's College London, London, United Kingdom Impact: The proposed algorithm enables spiral imaging with safe designs allowing on-the-fly adjustment, as acquisition parameters are modified. This flexibility enables safe and efficient use of gradients alongside normal imaging workflow.
16:33		607-03-004. Achieving Fast, High-Resolution Brain MR Elastography through Magnetization Preparation and Distributed Generalized Encoding Nicholas Pyontek, Alexa Diano, Mary Kramer, Alex Cerjanic, Curtis Johnson University of Delaware, Newark, United States of America Impact: By reducing scan times without compromising data quality, this technique improves both clinical and research practicality without jeopardizing patient/subject comfort. This method facilitates widespread implementation time-efficient brain MRE and emboldens investigation of small-scale neuromechanical characteristics in clinical and research settings.
16:44		607-03-005. HiLo Looping Star fMRI: Simultaneous structural & functional imaging in a single silent 3D whole-brain scan Florian Wiesinger, Ana Beatriz Solana GE Healthcare, Munich, Germany Impact: HiLo Looping Star unifies structural and functional MRI in a single silent 3D acquisition, overcoming trade-offs between spatial and temporal resolution. It streamlines workflows, provides quantitative information, and enables comfortable fMRI in noise-sensitive, auditory, or sleep studies—advancing next-generation neuroimaging.
16:55		607-03-006. Reduced-field-of-view sodium MRI with a simultaneous multi-slice differential multi-block presaturated UTE sequence Jason Reich, Kevin Harkins, Rachelle Crescenzi, Erin MacMillan, Rebecca Feldman University of British Columbia, Vancouver, Canada Impact: We optimized a simultaneous multi-slice ultrashort echo time sequence for sodium MRI to enable the acquisition of multiple slices at the same time. This sequence provides increased flexibility in imaging field-of-view and is expected to reduce sodium MRI scan times.
17:06		607-03-007. High-Acceleration Silent EPI with Reduced Distortion Using Ultrasonic Gradient Encoding Yahya Almasri, Edwin Versteeg, Jeroen Siero University Medical Center Utrecht, Utrecht, Netherlands Impact: We present ultrasonic EPI as a novel acquisition method for fast and silent neuroimaging (fMRI and diffusion). It reduces acoustic noise, improving subject comfort, and enables high acceleration with reduced geometric EPI distortions by employing densely sampled k-space readout lanes.
17:17		607-03-008. Near-silent DCE-MRI using incoherently-sampled, contrast-prepared Zero-TE imaging and a subspace-constrained reconstruction Shreya Ramachandran, Ali Syed, Shreyas Vasanawala, Michael Lustig University of California, Berkeley, United States of America Impact: By enabling near-silent DCE-MRI at high spatiotemporal resolutions, this framework could substantially improve the success rates of DCE-MRI by maximizing patient comfort and cooperation, especially among un-sedated neonates and young children.
17:28		607-03-009. Integrating a flow-diffusion model of O2 transport to qBOLD for contrast-agent- and gas-free mapping of deoxyCBV and CMRO2 Lucie Chalet, Davide Di Censo, Sara Pomante, Giulia Rocco, Elizabeth Fear, Francesca Graziano, Manuela Carriero, Fabrizio Fasano, Emma Biondetti, David Perpetuini, Richard Wise, Antonio Chiarelli University 'G.d'Annunzio' of Chieti-Pescara, Chieti, Italy Impact: Gray matter OEF, CMRO2 and deoxy-CBV can be mapped by combining a flow-diffusion model of oxygen transport within the qBOLD framework to provide a contrast-agent-free and challenge-free solution for clinical application.
17:39		607-03-010. Myocardial BOLD MRI with single-shot rFOV asymmetric spin echo multiple overlapping-echo detachment imaging Chenyang Dai, Shiwei Huang, Ping Huang, Che Wang, Liuhong Zhu, Jianjun Zhou, Liangjie Lin, Zhong Chen, Congbo Cai, Shuhui Cai Fujian Provincial Key Laboratory of Plasma and Magnetic Resonance, Xiamen University, Xiamen, China Impact: This study developed an ultrafast reduced field-of-view method for simultaneous T₂ and T₂^* mapping of the myocardium, which enables dynamic myocardial oxygenation assessment.
