Lee, S. T. Kim Samsung Medical Center, Seoul, Korea, Republic of Impact: Dynamic BOLD MRI with transient hypoxia can demonstrate cerebral perfusion changes before volume decline, suggesting the potential of this noninvasive technique as an early biomarker of dementia that may allow for screening of potential patients for dementia treatment.
		Computer Number: 19 2749. An automated q-aMRI pipeline for scalable brain displacement analysis: Enhancing speed, consistency, and clinical relevance View Presentation Video E. Clarkson, H. Kumar, J. Wright, I. Terem, E. Kwon, S. Holdsworth Mātai Medial Research Institue, Tairāwhiti Gisborne, New Zealand Impact: Large-scale quantification is essential to uncover the clinical significance of brain displacement in disease contexts. This automated q-aMRI pipeline streamlines the analysis process, enhancing the speed and scalability of displacement analyses in clinical cohorts.

Zhou, K. Dai, W. Shen, P. Lee, H. Chen, Z. Zhang Shanghai Jiao Tong University, Shanghai, China Impact: The integration of EPTI with PMC enhances DWI's clinical utility by providing high-resolution(1×1×5 mm³), distortion-free imaging for motion-sensitive patients, including children and patients with Alzheimer’s disease.
		Computer Number: 21 2751. 1mm Isotropic Resolution Whole Brain Microstructure Imaging at high SNR efficiency using 3D Multi-slab DMRI Demonstrated on the MAGNUS MRI View Presentation Video C-Y Lee, M. Mani University of Iowa, Iowa City, United States Impact: Addressing the long VAT of 3D-msDWI can provide a new technique to generate high SNR data that supports advanced microstructure studies.
		Computer Number: 22 2752. Effect of Gradient Impulse Response Function-based corrections on High-resolution FID Rosette Spectroscopic Imaging at 7T View Presentation Video A. Saucedo, C. Zhao, S. Mendoza, I. Pappas, D. Wang University of Southern California, Los Angeles, United States Impact: GIRF-based corrections for high-resolution FID MRSI have scarcely been shown in the literature. Accounting for gradient imperfections using the GIRF is crucial for non-Cartesian MRSI, particularly for high field and high-resolution acquisitions that demand high gradient performance.
		Computer Number: 23 2753. Direct Encoded Signal Control with Phase Distribution Graphs for readout-tailored multipulse pTx View Presentation Video S. Weinmüller, J. Endres, P. Dawood, M. Freudensprung, F. Glang, A. Nagel, M. Zaiss Universitätsklinikum Erlangen, Erlangen, Germany Impact: This approach enables more precise RF shimming for high-field MRI, improving image quality. It opens avenues for investigating optimized sequences across various readout strategies, reducing the need for manual tuning, which can enhance clinical and research imaging applications.
		Computer Number: 24 2754. Accelerating Quantitative MRI using Subspace Multiscale Energy Model (SS-MuSE) View Presentation Video Y. Chen, J. Rikhab Chand, S. Kecskemeti, J. Holmes, M. Jacob University of Virginia, Charlottesville, United States Impact: The proposed method enabled fast iterative reconstruction of the large-scale multi-contrast MRI data from the accelerated scan. The recovered source images can be used to differentiate the tissue types or quantitative mapping.
		Computer Number: 25 2755. Implementation and expansion of an analytic framework for generating spiral trajectories View Presentation Video J. Pipe, G. Krishnamoorthy University of Wisconsin Madison, Madison, United States Impact: This will help to enable spiral MRI, which may improve image quality and reduced scan times by 2-6X over conventional Cartesian methods with no loss in image quality.
