Spiral-mpDYCI for high-resolution multi-parametric dynamic contrast imaging Yang Chen, Nam Lee, Ye Tian, Junzhou Chen, Jiayu Xiao, Qingle Kong, Anthony Christodoulou, Debiao Li, Mark Shiroishi, Krishna Nayak, Eric Chang, Zhaoyang Fan University of Southern California, Los Angeles, United States of America Impact: High-resolution Spiral-mpDYCI may facilitate precision assessment of neurological disorders, such as brain tumor, based on voxel-wise multi-parametric mapping.
08:31		430-02-002. Arterial Spin Labeling MRI with Radial Sampling - End-to-End Open-Source Sequence Design and Image Reconstruction using BART Viktoria Buchegger, Daniel Mackner, Ingmar Sorgenfrei, Philip Schaten, Moritz Blumenthal, Ingrid Barth, Rudolf Stollberger, Martin Uecker Graz University of Technology, Graz, Austria Impact: This work introduces an end-to-end reproducible radial ASL MRI framework using BART, enabling easy sharing of ASL pulse sequences and incorporating advanced reconstruction methods to accelerate development, reproducibility, and dissemination of ASL imaging techniques across the MRI community.
08:42		430-02-003. High-resolution directional CSF velocity quantification in humans at 7T Madda Debiasi, Emiel Roefs, Kristian Nygaard Mortensen, Matthias van Osch, Henrik Lundell, Lydiane Hirschler Leiden University Medical Center, Leiden, Netherlands Impact: Our novel approach enables non-invasive, high-resolution measurements of CSF velocity across the whole brain and within small compartments. This proposed technique has the potential to advance our understanding of CSF dynamics in humans.
08:53		430-02-004. MRI in Clinical Practice: Enhanced Diagnosis of Focal Cortical Dysplasia using STAGE-EDGE Ethan Vyhmeister, David Utriainen, Sean Sethi, Samuel Barnes, Paul Kokeny, Adina Achiriloaie Loma Linda University, Loma Linda, United States of America Impact: STAGE-EDGE is a novel, time-efficient MRI sequence that can aid in the diagnosis of FCD by highlighting key findings or cortical thickening and abnormal subcortical white matter signal and critically impact management in some epilepsy patients.
09:04		430-02-005. Vendor-agnostic implementation of 3D radial gradient echo sequence with LIBRE water-excitation pulses for eye imaging Yiwei Jia, Mauro Leidi, Berk Acikgoz, Nils Plähn, Eva Peper, Joseph Woods, Jaime Barranco, Jean-Baptiste LEDOUX, Eleonora Fornari, Jessica Bastiaansen, Benedetta Franceschiello HES-SO University of Applied Sciences and Arts Western Switzerland, Sion, Switzerland Impact: The design of open Pulseq LIBRE enables transparency (open scripts and sequences) and cross-site deployment of fat-suppressed 3D radial GRE, improving study reproducibility and lowering technical barriers for MR-Eye studies and other applications.
09:15		430-02-006. Vendor-agnostic 4D Phase Contrast MRI: a complete open-source pipeline for velocities, displacement, and strain analysis Marta Maggioni, Sabine Räuber, Katarina Pus, Bostjan Šimunič, Francesco Santini University of Basel, Basel, Switzerland Impact: This open-source pipeline encompasses all steps from sequence programming to data analysis, enabling robust, vendor-independent CINE Phase Contrast MRI assessment of tissue motion and blood flow. It reliably retrieves velocity and strain values across three applications, supporting quantitative multi-center research.
09:26		430-02-007. An open-source workflow for MRI data acquisition and reconstruction using Pulseq: multi-site and cross-vendor validation Qingping Chen, Thomas Roos, Amaya Murguia, ADEPT UMR, Yuhai Xie, Pengcheng Xu, Shohei Fujita, Sebastian Littin, Yogesh Rathi, Jiayu Zhu, Berkin Bilgic, Jon-Fredrik Nielsen, Maxim Zaitsev University Medical Center Freiburg, Faculty of Medicine, University of Freiburg, Freiburg, Germany Impact: This work introduces an open-source, Pulseq-based workflow that harmonizes MRI data acquisition, formatting, and reconstruction across two field strengths (3T, 7T), five sites, and four vendors (Siemens, GE, Philips, United Imaging), improving transparency, reproducibility, and collaboration in multi-site, cross-vendor studies.
09:37		430-02-008. Single-breathhold 3D MR elastography in the liver, with simultaneous R2* and PDFF mapping Donovan Tripp, Anne-Sophie van Schelt, Omar Darwish, Karl Kunze, Nader Metwalli, Ahmed Gharib, Claudia Prieto, Rene Botnar, Ralph Sinkus, Radhouene Neji King's College London, London, United Kingdom Impact: MR elastography, PDFF and R₂* mapping provide non-invasive assessment of steatotic liver disease, but are currently performed in multiple breathholds. We propose a single-breathhold MRE sequence with simultaneous PDFF and R₂* mapping, which is validated in phantoms and healthy volunteers.
09:48		430-02-009. Open-source sequence implementation for 31P magnetization transfer MRS within the Pulseq framework Bela Seng, Justyna Platek, Marcel Awenius, Jan-Philipp Schmitz, Peter Bachert, Mark Ladd, Andreas Korzowski, Vanessa Franke German Cancer Research Center (DKFZ), Heidelberg, Germany Impact: The open-source implementation of a ³¹P magnetization transfer MRS sequence within the Pulseq framework, e.g., for measuring the ATP synthesis rate, is feasible, potentially paving the way to apply magnetization transfer experiments at different sites in a vendor-agnostic manner.
09:59		430-02-010. A Low-Cost, Modular, FPGA-Based MRI Console for Rapid Sequence Prototyping Guang Yang, Tao Li, Mark DelMonte, Yonghyun Ha, Chenhao Sun, Sebastian Theilenberg, SAJAD HOSSEINNEZHADIAN, Flor Parra Rodriguez, Anja Samardzija, Heng Sun, Horace Zhang, Ryan Gross, Terence Nixon, Gigi Galiana, R.
