This technique may provide a robust approach to free-breathing cardiac MRI.
16:04		451-03-003. On the interplay between the slice profile and myocardial motion in standard 2D bSSFP cine imaging: what do we really see? Tom Dresselaers, Anastasia Fambri, Alexandru Cernicanu, Jan Bogaert, Peter Gatehouse KU Leuven, Leuven, Belgium Impact: This abstract demonstrates both the reasons and mechanisms behind the fluctuating myocardium contrast during the cardiac cycle in 2D bSSFP cine imaging. It also explains why large flip angles are necessary to maintain consistent blood-to-myocardium contrast throughout the heart cycle.
16:06		451-03-004. Real-time TR-interleaved multiplanar bSSFP imaging Duc Le, Ye Tian, Prakash Kumar, Krishna Nayak University of Southern California, Los Angeles, United States of America Impact: TR-interleaved multiplanar bSSFP imaging is uniquely feasible at low field strengths and may improve motion tracking for interactive MRI applications and potentially enables beat-to-beat cardiac volumetry.
16:08		451-03-005. Clinical evaluation of DL Breath-hold and free breath CMR cine: A comparative study with standard breath-hold cine imageing Zhenhuan Wang, Junxian Liao, Guangwen Duan, Xinyi Wan, An Sun, Song Jiang, Yunmeng Wang, Xin Chen, Yuxin Cheng, Jiankun Dai, Qingqing Wen, Yi Xiao The Second Affiliated Hospital of Naval Medical University, Shanghai, China Impact: Sonic DL cine significantly reduced scan time and improved patient comfort. BH-Sonic can obtain superior image quality and equivalent functional accuracy to BH-Fiesta, while FB-Sonic maintained reliable cardiac function assessment despite minor quality reduction, expanding applicability to broader patient populations.
16:10		451-03-006. Incremental Prognostic Value of CMR Feature Tracking Derived Left Ventricular Strain in Chronic Aortic Regurgitation Bo Li, Yujie Liu, Shihua Zhao National Center for Cardiovascular Diseases and Fuwai Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing, China Impact: CMR-FT–derived LV strain enables earlier identification of patients with chronic moderate-to-severe AR at risk for adverse outcomes, potentially refining surgical timing and guiding individualized management beyond conventional volumetric and functional parameters.
16:12		451-03-007. A universal plug-and-play framework for rapid reconstruction of contrast-enhanced 5D free-running cardiac MRI Kevin Borsos, Augustin Ogier, Christopher Roy, Xavier Sieber, Milan Prša, Matthias Stuber, Ruud van Heeswijk, Roger Hullin, Orlando Simonetti, Tobias Rutz, Thomas Küstner, Jérôme Yerly Lausanne University Hospital (CHUV) and University of Lausanne (UNIL), Lausanne, Switzerland Impact: We present a framework for the reconstruction of contrast-enhanced radial free-running CMR data with inference times of just a few minutes. Our method generalizes to previously unseen data and offers potential for inline reconstruction, addressing key barriers to clinical adoption.
16:14		451-03-008. Free-breathing black-blood LGE imaging in a one-shot approach for rapid, motion free and diagnostic scar imaging Victor de Villedon de Naide, Sane Viola, Kalvin Narceau, Thaïs Génisson, Théo Richard, Ewan Barel, Thomas Küstner, Claire Bazin, Edouard Gerbaud, Pierre Jaïs, Matthias Stuber, Hubert Cochet, Aurelien Bustin IHU LIRYC, Heart Rhythm Disease Institute, Bordeaux, France Impact: The proposed black-blood one-shot sequence enables rapid sequence planning for MR technicians, simplified image interpretation for medical professionals through qualitative images free of residual motion artefacts, and more comfortable CMR protocol for patients, through free-breathing acquisitions.
16:16		451-03-009. Clinical Validation of a Vendor-Agnostic AI for Accelerated Cardiac MRI: A Prospective, Multi-Vendor Study in Post-Infarction Jin-Yi Xiang, Hui Tang, Yan Zhou, Lian-Ming Wu Shanghai Jiao Tong University School of Medicine Affiliated Renji Hospital, Shanghai, China Impact: This study validates a vendor-agnostic AI that reduces cardiac MRI time by 45%. It provides a practical solution for institutions with mixed hardware to improve workflow efficiency and increase scanner throughput without compromising diagnostic or quantitative accuracy.
16:18		451-03-010. A Deep Learning Framework for Automatic Scar Quantification in Hypertrophic Cardiomyopathy from Contrast-Free Cardiac MR Hanxi Liao, Yufan Qian, Lian-Ming Wu, Haikun Qi ShanghaiTech University, Shanghai, China Impact: This study presents an end-to-end framework combining diffusion-based cine-generated enhancement with automated segmentation for scar quantification in hypertrophic cardiomyopathy from contrast-free cardiac MR, potentially eliminating gadolinium use, thereby reducing scan time, costs, and risks in patients.
16:20		451-03-011. Arrhythmia Rejection Does Not Alter Left Atrial Fibrosis Quantification from 3D LGE in Patients with Atrial Fibrillation Jonathan Louis, KyungPyo Hong, Rod Passman, Daniel Kim Northwestern University Feinberg School of Medicine, Chicago, United States of America Impact: Motion-resolved compressed sensing reconstruction intrinsically demonstrates robustness to arrhythmia in 3D left atrial LGE, undermining the need for prospective rhythm control or complex rejection algorithms in clinical atrial fibrillation imaging workflows.
16:22		451-03-012. MRI in Clinical Practice: HFpEF With Normal NT-proBNP—Multiparametric CMR Confirms Diffuse Myocardial Fibrosis Rui Zhang, Yi Zhu The First Affiliated Hospital of Xi'an Jiaotong University, Xi'an, China Impact: CMR objectively confirmed HFpEF with diffuse fibrosis despite normal NT-proBNP, changing diagnostic certainty and care: the patient entered an HFpEF pathway with targeted therapy and risk-factor control rather than being dismissed as non-cardiac.
16:24		451-03-013. Cardiac Dixon MRF for Simultaneous T1, T2, T1ρ and Fat-Fraction Quantification at 0.55T Diego Pedraza, Dongyue Si, Karl Kunze, Rene Botnar, Claudia Prieto Pontificia Universidad Católica de Chile, Santiago, Chile, Chile Impact: Simultaneous mapping of T1, T2, T1ρ and FF in a single ~16s breath-hold scan at 0.55T could provide a more affordable and accessible approach for comprehensive assessment of cardiovascular disease.
