  Figure 668-04-001.  First Images from a 37 mT Inward-Outward Permanent Magnet Brain Scanner
Jules Vliem, Lyanne Budé, Irena Zivkovic
Eindhoven University of Technology, Eindhoven, Netherlands
Impact: This work will be the first demonstration of an imaging system built on the Inward-Outward (IO) magnet. Success will validate the IO array as a low-cost platform for ULF MRI and open a path for accessible, point-of-care brain scanners.
  Figure 668-04-002.  Integrating Relaxation and Susceptibility MRI for Distinct Iron Product Characterization
Ogechukwu Ngwu-Hyacinth, Ryan Willoughby, Jesse Jones, Mark Bolding
University of Alabama at Birmingham, Birmingham, United States of America
Impact: Quantitative iron mapping after hemorrhage can replace subjective MRI interpretation with biomarkers for lesion staging and progression. This approach could enhance diagnostic precision, predict rebleeding risk, refine management of cerebrovascular disorders and establish measurable biomarkers for research investigating iron-modulating interventions.
  Figure 668-04-003.  Neural Network Modeling with Synthetic b-Values Enables Accurate and Efficient Cervical Cancer Assessment
Albert Yen, Guangyu Dan, Cui Feng, Qingfei Luo, Kezhou Wang, Muge Karaman, Daoyu Hu, Zhen Li, Xiaohong Joe Zhou
University of Illinois Chicago, Chicago, United States of America
Impact: A neural network–based, model-free DWI framework with synthetic b-value augmentation enables accurate cervical cancer assessment using fewer acquisitions, reducing scan time by 41% while outperforming ADC analysis, advancing efficient, accurate, and clinically feasible machine-learning-based diagnostics.
  Figure 668-04-004.  Comparison of Nodule Detection Capability among MRI with Ultra-Short TE (UTE-MRI) and STIR Imaging on PET/MRI and FDG-PET/CT
Yoshiyuki Ozawa, Daisuke Takenaka, Takeshi Yoshikawa, Masao Yui, Kota Aoyagi, Takahiro Ueda, Masahiko Nomura, Masahiro Endo, Yoshiharu Ohno
Fujita Health University School of Medicine, Toyoake, Japan
Impact: PET/MRI has superior potential for nodule detection in oncologic patients as compared with PET/CT with and without breath-hold CT.
  Figure 668-04-005.  The Influence of Perfusion Effect in MR Cytometry Imaging
Zongshu Wang, Zhilin Yuan, Jiahui Zhang, Lei Wu, Yilan Ji, Wen Zhong, Fan Liu, Yonglan He, Hua Guo, Diwei Shi
Tsinghua University, Beijing, China
Impact: This study quantified the impact of perfusion on MR cytometry imaging. Results indicated that perfusion indeed leads to deviations in fitted parameters, but its impact on clinical diagnosis is very limited, perfusion can be neglected in clinics for model simplification.
  Figure 668-04-006.  Ultra-High Gradient MR Cytometry Enables Non-Invasive Quantification of HCC Microstructure and Aggressiveness
Beixuan Zheng, Diwei Shi, Caixia Fu, Yishi Wang, Yilan Ji, Fan Liu, Mengsu Zeng, Hua Guo, Ruofan Sheng
Zhongshan Hospital, Fudan University, Shanghai, China
Impact: MR cytometry provides non-invasive imaging parameters that significantly correlate with key pathological markers of HCC aggressiveness, aiding in pre-treatment risk stratification and guiding personalized treatment planning.
  Figure 668-04-007.  A Comparative Study of Artificial Intelligence–Assisted Compressed Sensing and Parallel Imaging in Placental MRI
Yunyun Lv, Jianli Yu, Peicheng li, Jiejun Cheng, Yichen Wang, Le Fu
Shanghai first maternity and infant hospital, Shanghai, China
Impact: ACS enables faster and higher-quality placental MRI without compromising diagnostic accuracy. This approach enhances patient comfort, reduces motion artifacts, and provides an efficient and clinically reliable imaging solution for prenatal assessment.
  Figure 668-04-008.  Real-Time Effects of body position on pulmonary function: A 0.55T MRI study
Nyvenn da Mota Alves de Castro , Navid Bonakdar, René Groh, Moritz Moss, David Leitão, Frederick Krischke, Patrick Morhart, Jana Hutter
Uniklinikum Erlangen, Erlangen, Germany
Impact: This pilot study demonstrates feasibility of comprehensive low-field MRI for lung physiology, combining volumetry and real-time lung water density mapping across positions. Initial results reveal gravity-driven redistribution, supporting future studies toward individualized assessment, therapeutic prediction, and computationally informed disease modeling.
  Figure 668-04-009.  Uniquely soft: evidence of uniqueness in viscoelastic intrinsic MR elastography enabled by the ultra-soft brain
Marius Burman Ingeberg, Elijah Van Houten, Jaco Zwanenburg
University Medical Center Utrecht, Utrecht, Netherlands
Impact: This work further establishes that the human brain is extraordinarily soft in its natural state and that iMRE can uniquely and reliably recover its viscoelastic properties without artificial stiffness constraints.
  Figure 668-04-010.  Oxygen-Enhanced T1 shortening of lung using Radial UTE VFA MRI
Saman Khodaei, Abhilash Kizhakke Puliyakote, Conner Wharff, keegan Staab, Andrew Hahn, Sean Fain
University of Iowa, Iowa City, United States of America
Impact: The free-breathing VFA-UTE technique provides a simple and time-efficient approach to generate high-resolution 3D parametric maps of oxygen uptake in the lung parenchyma that is representative of regional functional differences
  Figure 668-04-011.  Optimized 3D UTE MRI for Integrated, Radiation-Free Imaging of Lung, Rib Cage, and Spine
Jiaji Wang, Michael Carl, Jiayang Wu, James Lo, Xing Lu, Jiang Du, Jonathan Chung, Yajun Ma
University of California, San Diego, United States of America
Impact: The optimized 3D UTE acquisition enables integrated imaging of lung and bone without radiation exposure, offering a viable alternative to CT in scenarios where longitudinal or dose-sensitive examinations are required.
  Figure 668-04-012.  Free-Breathing 3D UTE MRI: A Robust Clinical Protocol for High-Quality Pulmonary Imaging Across Disease Types
Wen Yang, Mingran Shao, Qianqian Feng, Yang Yang, Zengping Lin, Hongyan Zhu
Nanjing Drum Tower Hospital, The Affiliated Hospital of Nanjing University Medical School, Nanjing 210008, China
Impact: This study establishes free-breathing 3D UTE for high-resolution lung MRI, providing robust, diagnostic-quality imaging without breath-hold constraints. It not only benefits a broader healthy population but also demonstrates exceptional utility in patients with pulmonary pathologies, enabling clear visualization of lesions.
  Figure 668-04-013.  Unraveling Asymmetries in Phase-Cycled Balanced SSFP Signals from Highly Ordered Biological Tissues
Yuxi Pang
St. Jude Children's Research Hospital, Memphis, United States of America
Impact: 
This work presents a novel theoretical framework for interpreting asymmetric phase-cycled bSSFP signals influenced by anisotropic water proton relaxation and the data acquisition scheme. The observed asymmetry index in brain white matter can be largely accounted for by this framework.
  Figure 668-04-014.  Differential diagnosis of MRI Multi-sequence Imaging Technology in NAION and DON
yongbin li, jinyi ma
Xi‘an NO.1 Hospital, Xi'an, China
Impact: This study identifies the "central bright spot sign" as a novel MRI biomarker for differentiating NAION from DON, achieving 92.93% diagnostic accuracy when combined with demographics, providing a non-invasive, objective tool for acute optic neuropathy diagnosis.
  Figure 668-04-015.  Improved equilibrium phase contrast enhanced bT1RESS MR using inner volume excitation
SRIKANT Kamesh Iyer, Tess Wallace, Amit Pursnani, Ioannis Koktzoglou, Robert Edelman
Siemens Medical Solutions USA, Inc., United States of America, United States of America
Impact: bT1RESS enables diagnostic-quality contrast-enhanced MRA several minutes after contrast administration but may be affected by wrap-around artifacts, especially in larger patients. Integrating inner-volume excitation with navigator-gated bT1RESS eliminates these artifacts, achieving high-quality, wrap-around artifact-free images with up to 14-fold acceleration.
