		462-01-001. Delineation and Characterization of Magnetization Transfer Attenuated Tumour Sub-Regions using Unsupervised Clustering Céline Dubroy-McArdle, Wilfred Lam, Greg Stanisz, Dafna Sussman Toronto Metropolitan University, Toronto, Canada Impact: This work introduces the first to my knowledge, automated framework for delineating MT-attenuated tumour sub-regions in brain metastases, enabling biologically informed target definition for stereotactic radiosurgery and improving understanding of intra-tumour heterogeneity through MRI signal derived habitats.
		462-01-002. Assessment of glioma biomarkers using amide proton transfer weighted MRI with and without fluid suppression Malte Knutsson, Tim Salomonsson, Anina Seidemo, Faris Durmo, Anna Rydelius, Xavier Sarda, Patrick Liebig, Mattias Belting, Johan Bengzon, Peter van Zijl, Linda Knutsson, Pia Maly Sundgren Lund University, Lund, Sweden Impact: These promising findings indicate that APTw MRI with patient-specific fluid suppression enhances biomarker prediction. This approach could decrease the need for invasive biopsies and serve as an alternative, particularly considering tumor heterogeneity.
		462-01-003. Dynamic PCASL angiography using a 3D-radial multi-spoke SPGR sequence: Comparing multi-label duration and dynamic readouts Andreas Petrovic, Shalini Amukotuwa, Andrew Gauden, Leon Lai, Martin Soellradl, Thomas Okell, Roland Bammer Monash University, Melbourne, Australia Impact: This study substantially improves the SNR and robustness of dynamic PCASL angiography, providing a more flexible and clinically viable tool for diagnosing cerebral vascular malformations. This is a key step toward clinical adoption.
		462-01-004. Pilot MRI Study for Evaluating Articular Cartilage Injury Using Intra-Articular 17O-Labeled Water in Ex Vivo Porcine Knees Hiroyuki Kameda, Minami Shimoma, Taro Fujiwara, Shotaro Fuchibe, Taro Igarashi, Yoshitaka Bito, Kazuyuki Minowa, Kohsuke Kudo Hokkaido University, Sappro, Japan Impact: This study demonstrates a novel MRI-based approach using ¹⁷O-labeled water and T2 mapping to visualize and quantify water permeability changes in articular cartilage, offering potential as an early imaging biomarker for osteoarthritis.
		462-01-005. Reducing ASL Signal Dropout at 3 Tesla and 7 Tesla Using Spiral In-Out Trajectories Yulin Chang, Manuel Taso, Wei-ching Lo, Nutandev Bikkamane Jayadev, Jan Kufer, Meher Juttukonda, Marta Vidorreta, Stephen Cauley, Ze Wang, John Detre Siemens Medical Solutions USA Inc., Boston, United States of America Impact: 3D stack-of-spirals allows whole-brain coverage in arterial spin labeling imaging but suffers from signal loss due to long readout and long echo trains. Spiral in-out trajectories can mitigate signal loss, which is particularly helpful in few-shot acquisitions.
		462-01-006. A Multimodal MRI Study Reveals Thalamic Neurovascular-Neurochemical Decoupling in Classical Trigeminal Neuralgia jingqi Jiang, Danyang Wang, Pengfei Zhang, Kai AI, Jing Zhang Department of Magnetic Resonance, Lanzhou, China Impact: This study suggests thalamic neurovascular-neurochemical decoupling as a core feature of CTN. The findings provide a novel pathophysiological framework and promising biomarkers for developing targeted, dimension-specific therapies.
		462-01-007. Quantitative Assessment of Iron Deposition in Subcortical Nuclei of Epilepsy Patients Using 7 Tesla MRI Fei Zhu, Yingying Tang, Bo Tao, Huilou Liang, Su Lui West China Hospital of Sichuan University, Chendu, China Impact: 7T quantitative susceptibility mapping enables sensitive detection of subcortical iron abnormalities, advancing biomarker discovery and precision monitoring in epilepsy.
		462-01-008. Multi-site, Multi-Vendor Quality Assurance Phantom Validation for 129Xe MRI Clinical Trials Consortium Protocols Mariah Costa, Conner Wharff, Riley Meyer, Saman Khodaei, Andrew Hahn, Abhilash Kizhakke Puliyakote, Sean Fain University of Iowa, Iowa City, United States of America Impact: A simple, quantitative ¹²⁹Xe gas phantom is proposed to enable reproducible, standardized quality assurance across scanners, providing a robust validation tool for harmonized clinical protocols and future ¹²⁹Xe MRI sequence and reconstruction development.
		462-01-009. Collaborative Multi-site Preclinical MRS Study (CoMP-MRS) – Preliminary Results Diana G.

Abdominal T1 mapping at 7 T Petr Bulanov, Johannes Grimm, Petr Menshchikov, Simon Schmidt, Stephan Orzada, Mark Ladd, Sebastian Schmitter Heidelberg University, Heidelberg, Germany Impact: This study provides the first comprehensive reference dataset of abdominal T₁ values at 7 T using a simple, robust GRE-IR method with B₁⁺ shimming. The measured T₁ values have the potential to serve in advanced quantitative techniques and simulations.
		462-01-012. MRI in Clinical Practice: Diagnosis of Intrapancreatic Splenule with Ferumoxytol MRI Sunny Rishi, Vipul Sheth Stanford Medicine, Stanford, United States of America Impact: Ferumoxytol, a SPIO based MR contrast agent, can be used to diagnose intrapancreatic splenule below the threshold for detection by the traditional nuclear medicine sulfur colloid scan, avoiding further imaging workup, radiation exposure, and unnecessary treatment.
		462-01-013. Dynamic Multi-Temporal APTw and ADC Histogram Analysis for Early Prediction of Neoadjuvant Chemoradiotherapy Response in Loca Yingying Zhang, Gang Huang Gansu University of Chinese Medicine, Lanzhou, China Impact: Dynamic multi-temporal APTw and ADC histogram analysis enables noninvasive and interpretable early prediction of treatment response in rectal cancer, providing a practical imaging biomarker for adaptive therapy planning and improving clinical decision-making in personalized oncology.
		462-01-014. Linking in vivo Cortical Structure and Function via High-Resolution Diffusion and Perfusion Imaging Tanxin Dong, Fanhua Guo, Hong Hsi Lee, Chenyang Zhao, Susie Huang, Danny Wang University of Southern California, Los Angeles, United States of America Impact: This work develops a simplified SANDI model for cortical microstructure mapping.
