		570-08-220. Near-Field Coupling wireless coils for 9.4T Rat Head MRI Paired with a Birdcage Coil: A comparative study Zhuoyang Lin, Ganghan Yang, Wei Cao, Wenhao Liao, Peiyu He, Feng Du, Nan Li, Zhiguang Mo, Qiaoyan Chen, Xiaoliang Zhang, Ye Li Paul C. Lauterbur Research Center for Biomedical Imaging, Shenzhen Institute of Advanced Technology, Chinese Academy of Sciences, Shenzhen, China Impact: This study validates near-field-coupled(NFC) wireless surface coils for rat brain MRI at 9.4 T through comparative experiments using a birdcage coil(BC). The result demonstrates wireless multiple loop coil arrays provide superior image coverage/depth, and sensitivity, aiding small animal coil design.
		570-08-221. Evaluation of Cerebral Blood Flow Dynamics in Rat Brain Using Phase-Contrast MRI kamel abderrahim, Sidy Fall, Olivier Baledent Université de Picardie Jules Verne (UPJV), Amiens, France Impact: This study demonstrates the feasibility of non-invasive quantification of cerebral arterial inflow and venous outflow in rats using phase-contrast MRI. It provides new insight into cerebrovascular coupling, physiological variability, and technical challenges in preclinical hemodynamic imaging.
		570-08-222. Reliability of Dental-Dedicated Ultrashort Echo Time MRI for Visualization of Mandibular Anatomy in ex vivo Human Specimens Karen Kettless, Gabriela Salatino Liedke, Stefan Sommer, Rubens Spin-Neto Siemens Healthcare A/S, Ballerup, Denmark Impact: This study demonstrates the feasibility of dental-dedicated MRI (ddMRI) using ultra-short echo time (UTE) research application sequence for high-resolution imaging of mandibular anatomy, allied to the fact that preservation conditions significantly influenced image quality.
		570-08-223. Neurometabolic similarity matrix to study metabolic connectivity in chronic hepatic encephalopathy: a preliminary study Thi Ngoc Anh Dinh, Gianna Nossa, Tan Toi Phan, Federico Lucchetti, Valerie McLin, Paul Klauser, Cristina Cudalbu CIBM Center for Biomedical Imaging, Lausanne, Switzerland Impact: This preliminary data suggests disrupted interregional metabolic coordination in the BDL rat model of chronic hepatic encephalopathy, revealing network-level metabolic dysfunctions and highlighting the potential of MRSI-based approaches for translational biomarker discovery.
		570-08-224. Validation of anisotropic diffusion at 5T using a hollow fiber phantom Robert Welsh, Kate Fissell, Guangyu Dan, Qi Liu, Peter Martin, Anthony Zuccolotto, Walter Schneider University of California Los Angeles, Los Angeles, United States of America Impact: Demonstrating that ground truth phantom physical parameters are accurately estimated at 5.0T is a necessary step towards quantitative MRI in humans.
		570-08-225. Investigating the effect of focused ultrasound on relaxation and oxygenation in an intracerebral haemorrhage stroke rat model Fabian Küppers, Ezequiel Farrher, Kuan-Hung Cho, Sheng-Min Huang, Yi-Hua Hsu, Ming-Jye Chen, Chia-Ching Pan, Hsin-Yun Chang, Chang-Hoon Choi, N. Jon Shah, Abel Po-Hao Huang, Gin-Shin Chen, Li-Wei Kuo Forschungszentrum Juelich, Juelich, Germany Impact: Additional multi-echo GE acquisition with T₂ quantification on an ICH stroke rat model utilising FUS application enables OEF estimates. Baseline MR parameters in the cortical region agree with previous results, and OEF increases following the application of FUS stimulation.
		570-08-226. In Vivo MRI Reveals Melatonin Alleviates Hypoxic-Ischemic Brain Damage by Suppressing TXNIP/Trx-1/GPX4-Mediated Ferroptosis Xiaoli Wang, Youcheng Qin, Peilun Xiao, Xinyue Zhang, Xiaozu Zhang, Haimo Zhang, Yijing Wang, Miao Yu, Peng Wu Shandong Second Medical University, Weifang, China Impact: This study identifies melatonin as a promising therapy for neonatal brain injury and validates the TXNIP/Trx-1/GPX4 axis as a key target, enabling future clinical trials and the use of MRI for non-invasive treatment monitoring.
		570-08-227. A Preclinical Susceptibility Phantom for Quantitative Evaluation of QSM Algorithms in the Rat Brain Belal TAVASHI, Leen HAKKI, Esin Ozturk Isik, Pinar Özbay Boğaziçi University Institute of Biomedical Engineering, Istanbul, Turkey Impact: Phantoms enable optimization of preprocessing algorithms, because reference values are known and used to evaluate performance. This helps answer questions like what algorithm works best for a specific organism, how do various factors affect performance and how to overcome hurdles.
		570-08-228. Effects of modifiable dementia risk factors on brain metabolism and structure through multimodal MRI in transgenic mice Gianmauro Palombelli, Valentina Zecca, Gabriele De Luca, Valeria SImonelli, Paola Piscopo, Federica Perrone, Alessio Crestini, Laura Ricceri, Nicola Vanacore, ROSSELLA CANESE Istituto Superiore di Sanità, Rome, Italy Impact: Our results demonstrate that modifiable risk factors for dementia can influence brain metabolism and structure. These changes can be monitored non-invasively using multimodal MRI. These findings may inform the design of future clinical trials and support public health intervention strategies.
		570-08-229. Multiparametric mapping of tumor hypoxia in a human neuroendocrine tumor mouse model Mikael Montelius, Lukas Lundholm, Maja Sohlin, Oscar Jalnefjord, Eva Forssell-Aronsson, Maria Ljungberg University of Gothenburg, Gothenburg, Sweden Impact: This work will contribute to the development of new, non-invasive imaging tools for characterization, therapeutic decision making and therapy response assessment in hypoxic solid cancers, which are associated with poor prognosis, radiation therapy resistance and metastatic disease.
