08:30		606-01-001. Non-invasive Characterization of Perivascular Subarachnoid Spaces Nina Fultz, Madda Debiasi, Emiel Roefs, Geir Ringstad, Marianne AA van Walderveen, Jeroen de Bresser, Matthias van Osch, Lydiane Hirschler C.J. Gorter MRI Center, Leiden University Medical Center, Netherlands Impact: Increased CSF mobility around major cerebral arteries suggests the presence of a CSF ‘highway’ within the perivascular subarachnoid space, distinct from the surrounding subarachnoid space.
08:41		606-01-002. Multiphoton Parallel Transmission at 7T Using Oscillating Gradients Tanya Deniz Ipek, Vaughan Abakians, Victor Han, Chunlei Liu University of California, Berkeley, United States of America Impact: Multiphoton excitation with oscillating gradients and synchronized sinusoidal RF phase modulation enhances the spatial control of parallel transmission, achieving higher transmit B₁ homogeneity at 7T with reduced RF energy, offering a promising direction for next-generation ultrahigh field excitation design.
08:52		606-01-003. Mesoscale Multiparametric qMRI at 7T with Multi-Echo vNav-QALAS and Self-Supervised Reconstruction Yohan Jun, Yuting Chen, Xingwang Yong, Divya Varadarajan, Robert Frost, Andre van der Kouwe, Ovidiu Andronesi, Camilo Jaimes, Michael Gee, Borjan Gagoski, Berkin Bilgic Harvard Medical School, Boston, United States of America Impact: This study proposes multi-echo vNav-QALAS at 7T for motion- and B₁^⁺-robust, mesoscale multiparametric mapping. By optimizing sequence design and reconstruction, it enables 450µm isotropic T₁, T₂, T₂^*, and QSM maps, advancing ultra-high-field qMRI toward efficient and comprehensive tissue characterization.
09:03		606-01-004. In-vivo mapping of whole-brain venous angioarchitecture and T2* at 350 microns with servo navigation and pTX at 7T and 11.7T Rüdiger Stirnberg, Matthias Serger, Philipp Ehses, Omer Faruk Gulban, Franck Mauconduit, Malte Riedel, Dimo Ivanov, Klaas Prüssmann, Nicolas Boulant, Tony Stoecker German Center for Neurodegenerative Diseases (DZNE e.V.), Bonn, Germany Impact: Simultaneous whole-brain T₂* mapping and in-vivo venous angioarchitecture mapping at 350 μm isotropic is feasible at 11.7T (7T) within 11 (15.5) minutes scan time. To this end, multi-echo data were acquired using segmented 3D-EPI with pTX and prospective motion+field correction.
09:14		606-01-005. Real-time pTx-Spoke pulse design for whole-brain SMS acquisition with improved SAR-hopping via Helical Spoke rotation Zimu Huo, Omer Oran, Kyle Gilbert, Ravi Menon, Victor Stenger, Kawin Setsompop Stanford Medicine, Stanford, United States of America Impact: A SAR-constrained pTx-Spoke-RF-pulse was developed for B1+-mitigated SMS acquisition at 7T with improved SAR-hopping via cross-slice helical spoke rotation, where MultiLayer-Perceptron-based prediction is used to achieve real-time, subject-specific pulse generation. The approach enables high-quality, real-time pTx-SMS pulses with low SAR.
09:25		606-01-006. First resting-state fMRI results at 11.7T Joseph Obriot, Zaineb Amor, Matthias Serger, Rüdiger Stirnberg, Philipp Ehses, Malte Riedel, Tony Stoecker, Klaas Prüssmann, Shajan Gunamony, Son Chu, Alexis Amadon, Alexandre Vignaud, Vincent Gras, Florent Meyniel, Franck Mauconduit, Caroline LeSter, Nicolas Boulant Université Paris-Saclay, CEA, CNRS, BAOBAB, Neurospin, Gif-sur-Yvette, France Impact: Functional networks were extracted from resting-state fMRI at 11.7T employing run-time motion and field corrections with retrospective phase equalization. Compared to 7T, tSNR maps and connectivity analyses show great promises in increasing further the resolution of fMRI at 11.7T.
09:36		606-01-007. Stabilization of 3D-EPI time series at 11.7T by servo navigation and PEERS Malte Riedel, Matthias Serger, Philipp Ehses, Joseph Obriot, Rüdiger Stirnberg, Franck Mauconduit, Caroline LeSter, Tony Stoecker, Nicolas Boulant, Klaas Prüssmann ETH Zurich and University of Zurich, Zurich, Switzerland Impact: fMRI at high-field enables high functional sensitivity with fine spatial localization but is increasingly susceptible to motion and scanner imperfections. Servo navigation and PEERS combine run-time motion and field corrections with retrospective phase corrections to mitigate contaminations and improve stability.
09:47		606-01-008. FastGRAPE for 3D non-selective pulse design at 11.7 T Joseph Brégeat, Natalia Dudysheva, Aurélien Massire, Alexandre Vignaud, Nicolas Boulant, Franck Mauconduit, Vincent Gras CEA NeuroSpin, Paris-Saclay University, CNRS, Gif-Sur-Yvette, France Impact: This study demonstrates the potential of the fastGRAPE design approach to efficiently optimize both tailored and calibration-free pulses for MP2RAGE and 3D TSE sequences at 11.7 T through comparative simulations and in vivo experiments
09:58		606-01-009. Motion and B₁ corrected cardiac ²³Na MRI in chronic kidney disease at 7 T Laurent Ruck, Armin NAGEL, Benedikt Zobler, Nico Egger, Simon Konstandin, Michael Uder, Christoph Kopp University Hospital Erlangen, Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU), Erlangen, Germany Impact: This work demonstrates the feasibility of cardiac ²³Na/¹H MRI at 7T, enabling noninvasive assessment of myocardial sodium alterations in chronic kidney disease. The approach may improve understanding of sodium dysregulation in cardiovascular disease and support early detection and therapy monitoring.
10:09		606-01-010. Task-based fMRI at 11.7T: Assessing Feasibility, Stability, and Reliability on the Iseult Scanner Zaineb Amor, Joseph Obriot, Matthias Serger, Malte Riedel, Klaas Prüssmann, Son Chu, Shajan Gunamony, Rüdiger Stirnberg, Philipp Ehses, Tony Stoecker, Florent Meyniel, Alexis Amadon, Alexandre Vignaud, Vincent Gras, Franck Mauconduit, Caroline LeSter, Nicolas Boulant Institute for Neuromodulation, Paris, France Impact: This first human task-based fMRI study using the Iseult scanner is a proof-of-concept that illustrates the feasibility and reliability of functional imaging in humans at 11.7T paving the way for studies where the spatio-temporal resolution would be pushed further.
