  5248. Predictive Value of Hemodynamic Forces Derived from Cardiac Magnetic Resonance in Adverse Ventricular Remodeling
X. Yue, J. Qi, M. Hu, J. Li, T. Li, K. He
Medical Innovation Research Department, Chinese PLA General Hospital, Beijing, China
Impact: HDF metrics from CMR cine imaging provide a novel, non-invasive approach for predicting adverse ventricular remodeling, with high predictive accuracy, supporting personalized patient management and early intervention strategies.
  5249. Analysis of image success rate, image quality and influencing factors of 3.0T whole-heart non-contrast MR coronary angiography in 1053 cases
y. jiang, w. liu, y. yuan, s. luo, d. jin
jiangsu province official hospital, Nan jing, China
Impact: Our study to improve image quality can shorten scanning time, increase success rate, and significantly improve image quality. It is especially suitable for examination of elderly and respiratory unstable patients.
  5250. Evaluation and Robustness Assessment of Cardiac Diffusion in Python (CarDpy)
T. Cork, A. Hannum, M. Loecher, D. Ennis
Stanford University, Stanford, United States
Impact:

CarDpy is an open-source cardiac diffusion data processing toolbox that enables community development and promotes rigorous science. Each post-processing step was evaluated to estimate the impact on improving the quality of several tensor metrics.

  5251. Longitudinal changes in epicardial adipose tissue volume in patients with heart failure following a 6-week weight-loss diet intervention
N. Mahalingam, C. Crabtree, K. Binzel, A. M. Castillo, J. Volek, Y. Han, O. Simonetti
The Ohio State University, Columbus, United States
Impact: Significant EAT volume changes greater than the repeatability coefficient were observed in patients with heart failure following a 6-week weight-loss diet. Cardiac MRI is sensitive in detecting changes in EAT volume that accompany weight loss induced by diet intervention.
  5252. Determining the normal size of the pediatric abdominal aorta in MRI.
C. Metz, A. Pohrt, K. Glutig, M. S. Anders, S. Veldhoen
Charité - Universitätsmedizin Berlin, corporate member of Freie Universität Berlin und Humboldt-Universität zu Berlin, Berlin, Germany
Impact: Establishing reference values for the abdominal aorta in children is essential for the diagnosis and monitoring of cardiovascular disease.
  5253. Risk Stratification of Sudden Cardiac Death in Non-Ischemic Cardiomyopathy: Towards Arrhythmogenic Substrate Assessment in Cardiac MRI
D. Zhou, M. Lu
Fuwai Hospital, Beijing, China
Impact: Our findings suggest that LGE and ECV metrics can enhance risk stratification and support personalized prognostic strategies in managing NICM patients, improving clinical decision-making.
  5254. Advancing Vascular Segmentation in Ferumoxytol-enhanced MRA: A Comparative Study of nnUNet and SegMamba
S. Li, T. Yoshida, K-L Nguyen, J. Finn, X. Zhong
Department of Radiological Sciences, University of California Los Angeles, Los Angeles, United States
Impact: This study explores automated vascular segmentation in FE-MRA and demonstrates that nnUNet outperforms SegMamba, offering a more reliable and automated approach.
  5255. The nonlinear association of resting heart rate and left ventricular global longitudinal strain in the patients with metabolic syndrome
X. Li, S. Yu, R. Xu, Z. Yang
West China Hospital of Sichuan University, Chengdu, China
Impact: Higher RHR is independently associated with LVGLS in patients with MetS, indicating that regular monitoring and early intervention for higher RHR may help prevent further decline in cardiac function.
  5256. Radiomics Analysis of Cardiac Magnetic Resonance Images for Differentiating Fabry Disease from Hypertrophic Cardiomyopathy
Y-F Huang, P-H Chiu, M-T Wu, T-Y Huang, H-W Chung, H-H Peng
National Tsing Hua University, Hsinchu, Taiwan
Impact: The RF classification combined with cine image features selected by MI could distinguish FD from HCM. The selected features included shape and texture categories, illustrating the potential of radiomics features in identifying subtle morphological and myocardial texture changes in FD.
  5257. MR-based evaluation of cardiac strain and ejection fraction in patients with dilated cardiomyopathy and hypertrophic cardiomyopathy
J. Sreekumar, M. Gunasingh, R. Krishna Narayana, S. Kaza, J. Neelavalli, B. Reddy
Indian Institute of Technology, Hyderabad, Hyderabad, India
Impact: This study highlights the potential of integrating strain data into clinical use as an early indicator for risk stratification, particularly in HCM patients, leading to effective interventions and improved outcomes.
  5258. Incremental Effects of Obesity on Myocardial Interstitial Fibrosis and Subclinical Left Ventricular Systolic Dysfunction in Patients withT2DM
X-M Li, L. Jiang, X. Liu, Y-K Guo, Y. Li, Y. Ren, z. yang
West China Hospital, Sichuan University, Chengdu, China
Impact: Appropriate obesity management may be beneficial for cardiac health in patients with T2DM, which should be thoroughly evaluated in future longitudinal studies. 
  5259. Cardiac MR tissue tracking to assess the mediation effect of amino acid metabolism on left ventricular damage in obese people
J. Lyu, C. Zhang, L. Mei, L. Cui, J. Xia, M. Liu, A. Xing, X. Qu
The Second Hospital of Dalian Medical University, Dalian, China
Impact: Our findings on the effect of amino acid metabolism and obesity on left ventricular function provide a basis for clinical management and treatment of comorbidities.
  5260. Assessing Strength and Reproducibility of Left Atrial – Left Ventricular Strain Coupling
S. Sreedhar, T. Chitiboi, M. Pradella, M. Elbaz
Northwestern Feinberg School of Medicine, Chicago, United States
Impact: This study establishes that left atrial circumferential and longitudinal strain are moderately-to-strongly correlated with left ventricular strain in healthy volunteers. Within ventricular systole, this measure demonstrates high reproducibility. This LA-LV coupling coefficient should be further explored in cardiac pathologies.
  5261. Dynamic Pulmonary Vessel Analysis in Free-Breathing MRI using 2D-U-Net Segmentation
J. Glandorf, M. Wernz, F. Klimeš, A. Voskrebenzev, M. Gutberlet, F. Wacker, J. Vogel-Claussen
Hannover Medical School, Hannover, Germany
Impact: This study demonstrates the potential of automated MRI-based vessel analysis to identify distinct hemodynamic changes in chronic lung diseases like COPD and PH. It could offer a non-invasive method to differentiate disease subtypes and monitor treatment responses in clinical practice.
