		569-02-001. A First Attempt at Solving the Bloch Equations on Quantum Computers José Cruz Serrallés, Oluwadara Ogunkoya, Doga Kurckuoglu, Silvia Zorzetti, Riccardo Lattanzi New York University Grossman School of Medicine, New York, United States of America Impact: This work demonstrates the feasibility of solving the Bloch equations on quantum computers. Quantum algorithms could greatly enhance model-based quantitative MRI techniques like Magnetic Resonance Fingerprinting by leveraging quantum parallelism to simulate larger problems and finer dictionaries than currently feasible.
		569-02-002. Robustness of Golden-Angle Compressed Sensing with Temporal Total Variation (tTV) Reconstruction for MRgPTS Implementation Naohiro Yagyu, Keito Nagayama, Nagaaki Kamiguchi, Tomoyuki Haishi, Yasuhiko Terada The University of Tsukuba, Tsukuba, Japan Impact: This study is the first to validate GA-CS-tTV in a proton scanning magnet environment. We provide a viable technical solution for the critical SM-artifact problem, establishing a crucial foundation for the clinical realization of real-time image-guided proton therapy.
		569-02-003. Rotating frame zeugmatography (RFZ) meets Selective Encoding through Nutation and Fingerprinting (SENF) Christopher Vaughn, Reid Bolding, Mark Griswold, William Grissom Case Western Reserve University, Cleveland, United States of America Impact: This novel Selective Encoding through Nutation and Fingerprinting (SENF) sequence approach combines principles of Rotating frame zeugmatography (RFZ) and SENF to enable independent design of spatial encoding with controllable resolution for SENF sequences.
		569-02-004. Insight into high quality ASL: multi-PLD with 3D-EPI readout at 5T Zhonghui Li, xiaoyuan Fan, Hualu Han, Feng Feng Peking Union Medical College Hospital, Beijing, China Impact: This study demonstrates that 3D-EPI readout enables high-quality multi-PLD ASL imaging at 5T with reduced blurring and improved SNR compared to GRASE. The approach enhances quantitative perfusion mapping and may facilitate more accurate cerebrovascular assessment at ultra-high field MRI.
		569-02-005. Typed Parameters for MRI: A Unit-Safe CRTP Class that Enable easy and efficient Parameter Math Chenguang Zhao MethodVerse LLC, Orlando, United States of America Impact: This work delivers unit-safe MRI parameter handling for sequence design and improves cross-vendor portability, making parameter calculations and code easier to maintain and reuse across platforms.
		569-02-006. In Vivo 31P-MRS Reveals APOE4-Linked Metabolic Vulnerability in Hippocampus Qianyun Su, Qiurong Yu, Xinyan Li, Xi Wang, Ruixi Li, Jinyuan Weng, Peng Wu, Yuxiang Teng, Yixin Zhou, Naying He, Jianfang Ma, Fuhua Yan College of Health Science and Technology, Shanghai Jiao Tong University School of Medicine, Shanghai, China Impact: This study delineates the critical link between APOE genotype and cerebral energy metabolism, establishing metabolic markers as sensitive, pre-atrophy indicators for preclinical AD intervention.
		569-02-007. 31P MRSI coil combination using 23Na sensitivity information: Monte Carlo simulation and in vivo validations Jiying Dai, Alexander Raaijmakers, Dennis Klomp University Medical Center Utrecht, Utrecht, Netherlands Impact: This study demonstrates that cross-frequency coil combination using ²³Na sensitivity enables bias-free, SNR-efficient ³¹P MRSI. Validated through EM, Monte Carlo, and MR experiments, this approach advances quantitative metabolic imaging, particularly in low-SNR tissues, and is extendable to other multi-tuned systems.
		569-02-008. Multiphoton Simultaneous Transmission and Reception MRI Hannah Kempfert, Victor Han, Chunlei Liu University of California, Berkeley, United States of America Impact: Two-photon simultaneous transmission and reception MRI shifts the MRI signal away from the transmit band, allowing better transmit/receive isolation. Potential impacts include high SNR efficiency, robustness to motion/flow, and better imaging of ultra-short-T₂ tissues and rapidly decaying X-nuclei.
