		470-04-097. Spectral optimization of rosette k-space trajectories for improved fat suppression Xin Bai, Haotian Hong, Yuyang Ren, Wenlei Shang, Zijian Zhou, Peng Hu ShanghaiTech University, Shanghai, China Impact: To achieve better fat suppression using the rosette trajectory, we introduced a framework that combines modeling and parameter search to optimize this effect.
		470-04-098. Graphite-Silicone Composite Neck Shim Pad for Enhanced B0 Homogeneity and Fat Suppression in Ultra-High-Field MRI Yihan Yang, Haotian Hong, Ziyu Liu, Weijun Zhang, Peng Hu, Zhihua Ren ShanghaiTech University, Shanghai, China Impact: This simple, low-cost passive shim pad enables immediate, hardware-independent enhancement of $\bold{B_0}$ uniformity and fat suppression in ultra-high-field cervical spine MRI, facilitating broader clinical adoption.
		470-04-099. Time-Efficient Fat Suppression for 5D Flow MRI using HydrOptiFrame Paolo Garelli, Fabienne Dirbach, Xavier Sieber, Efena Akporeha, Thara Nallamothu, Jean-Baptiste LEDOUX, Ruud van Heeswijk, Isabel Montón Quesada, Augustin Ogier, Jérôme Yerly, Stanislas Rapacchi, Michael Markl, Matthias Stuber, Tobias Rutz, Christopher Roy Lausanne University Hospital (CHUV) and University of Lausanne (UNIL), Lausanne, Switzerland Impact: This work enhances 5D flow MRI through optimized WE-RF pulses, achieving fat suppression without increasing scan time. This method may benefit patients with substantial adipose tissue, improving image quality and flow quantification for broader clinical adoption of whole-heart flow imaging.
		470-04-100. Fat Selective Excitation for Fat Signal Cancellation in APT-Weighted Imaging Holger Eggers, Elena Vinogradov, Jochen Keupp Philips Innovative Technologies, Hamburg, Germany Impact: Fat-selective excitation with a flip angle of 90° may alleviate persisting artifacts from fat signal in amide proton transfer-weighted imaging without prolonging the acquisition or requiring elaborate postprocessing.
		470-04-101. Enhanced Design of Spectral-Spatial Pulses for Fat Saturation by Leveraging Dixon-Based Water-Fat Separation Yu Chen, Nicolas Gross-Weege, Kun Zhou, David Grodzki Magnetic resonance, Siemens Shenzhen Magnetic Resonance Ltd., Shenzhen, China Impact: This method enables more robust fat saturation with reduced shading artifacts, promising improved diagnostic confidence in clinical MRI.
		470-04-102. Robust Deep Learning Water-Fat Quantification for Small Water-Fat Phase Shift at Low Field Xuehong Lin, Yujiao Zhao, Shi Su, Ye Ding, Liubin Wu, Alex T. L. Leong, Vick Lau, Wai Kay SETO, Ed X Wu The University of Hong Kong, Hong Kong, China Impact: A deep learning strategy is presented to robustly predict water-only and fat-only images from chemical shift encoded multi-echo images. We successfully demonstrated its efficacy and robustness for water-fat separation with small water-fat phase shift or fewer echoes.
		470-04-103. Water-Fat Separated Time-Resolved MR Fingerprinting (TRMRF) for Abdominal Quantitative Imaging Xiaoxi Liu, Di Cui University Of California, San Francisco (UCSF), United States of America Impact: The proposed water-fat separated TRMRF technique enables rapid, composition-resolved abdominal mapping within a single breath-hold, improving quantification in organs with fat. It may enhance liver and renal disease characterization and guide development of reliable multiparametric biomarkers for abdominal imaging.
		470-04-104. Echo-dependent Flip Angle acquisition and Physics-informed Deep Learning reconstruction for high-resolution fat-water imaging Moorthy Ganeshkumar, Devasenathipathy Kandasamy, Esha Baidya Kayal, Amit Mehndiratta Indian Institute of Technology, Delhi, India Impact: High-resolution fat-water imaging, limited due to SNR restrictions, can facilitate seamless delineation of smaller organs like pancreas, where fat quantification analysis is of prognostic value. This study proposes a novel acquisition strategy and a reconstruction method for the same.
		470-04-105. mDixon non-contrast coronary MR angiography accelerated by compressed sensing for detection of coronary artery stenosis Jingji Ma, Zhiwei Shen, Benqiang Yang, Xinxiang Zhao The Second Affiliated Hospital of Kunming Medical University, Yunnan Province, China Impact: It may serve as a promising screening tool and further be integrated into clinical protocols with myocardial perfusion and scar imaging for a comprehensive evaluation of CAD.
