Skill Level: Advanced

13:40		530-03-001. High-Bandwidth PRF-Shift MR Thermometry for Temperature Imaging Near Metal William Grissom, Sarah Garrow, Mark Griswold Case Western Reserve University, Cleveland, United States of America Impact: The proposed high-bandwidth MR thermometry method enables temperature imaging in tissues with large magnetic field offsets or gradients, such as those near metallic ablation probes or needles. This is desirable to monitor thermal therapies but not possible with existing methods.
13:51		530-03-002. RF-induced Heating of Braided Venous Stents during Expansion: SAR Simulations and Temperature Measurements Lisa Regler, Simon Reiss, Ali Özen, Klaus Düring, Wibke Uller, Michael Bock University Medical Center Freiburg, Freiburg, Germany Impact: This study showed that tip heating of braided venous stents decreases up to 96% during their expansion. The hot-spot at the stent tip was confirmed with MR-thermometry and simulated SAR. MR-guided interventions and post-implantation imaging requires adaptation of SAR limits.
14:02		530-03-003. Characterizing the Spatiotemporal Thermal Effects of Pulsed Microwave Ablation with Computational Modeling and MR Thermometry Qing Dai, Jason Chiang, Wenqi Zhou, David Lu, Holden Wu Samueli School of Engineering, University of California Los Angeles, Los Angeles, United States of America Impact: This is the first study to utilize MR thermometry for characterizing the thermal effects of pulsed microwave ablation. When combined with computational modeling, this joint computational-experimental approach enables optimization of energy-delivery strategies to achieve safer, more predictable microwave ablation.
14:13		530-03-004. Low-latency real-time 3D MRI for guiding cardiovascular interventions Prakash Kumar, Rajiv Ramasawmy, Ahsan Javed, Duc Le, Kendall O'Brien, Andrea Jaimes, Dominique Franson, Kelvin Chow, Fang Dong, Florian Maier, Robert Lederman, Krishna Nayak, Adrienne Campbell-Washburn University of Southern California, Los Angeles, United States of America Impact: 3D real-time imaging, low-latency image reconstruction, and novel 3D visualization can improve device tracking in MRI-guided cardiac interventions.
14:24		530-03-005. Improved Catheter Localization using Coil Tracking in Tx-mode Felix Spreter, Kian Tadjalli Mehr, Johannes Fischer, Ali Özen, Michael Bock, Simon Reiss University Medical Center Freiburg, Faculty of Medicine, University of Freiburg, Freiburg, Germany Impact: Tx-mode catheter coil tracking improves and simplifies catheter localization during an MR-guided intervention by projecting the tip location and catheter outline onto the real-time image even when the catheter is outside of the imaging plane.
14:35		530-03-006. Intralaminar Thalamic Recruitment Predicts Clinical Benefit after MRgFUS Thalamotomy for Essential Tremor Darren Clark, Conrad Rockel, Samuel Pichardo, Camila Aquino, Davide Martino, Tejas Sankar, Fady Girgis, Zelma Kiss, G. Bruce Pike University of Calgary, Calgary, Canada Impact: Intralaminar thalamic recruitment mediates motor network reorganization after MRgFUS thalamotomy, revealing a systems-level mechanism of recovery. These results link thalamocortical plasticity to clinical outcome in essential tremor and establish a mechanistic framework for imaging-based biomarkers of adaptive network dynamics.
14:46		530-03-007. Calculating Tissue Heating from Simultaneous Transcranial Ultrasound Stimulation and MRI Kristen Zarcone, Shota Hodono, Giuseppe Carluccio, Ming Lu, Xinqiang Yan, Lennart Verhagen, Martijn Cloos, David Norris, Samuel Pichardo, Christopher Collins, Kim Pauly, William Grissom Case Western Reserve University, Cleveland, United States of America Impact: MRI provides targeting and readouts for TUS, but their simultaneous use raises the possibility of compounded heating. We report a validated framework for simulating heating caused by TUS + MRI and present preliminary simulated heating results.
14:57		530-03-008. A Patient-specific Cross-attention Future Orthogonal Planes (CAFOP) Framework for Adaptive MRI-guided Radiation Therapy James Grover, Andrew Phair, Michael Ferraro, Hilary Byrne, Paul Keall, Michael Jameson, David Waddington The University of Sydney, Sydney, Australia Impact: Our patient-specific cross-attention future orthogonal planes (CAFOP) framework predicts the next cine-MR image for all orthogonal imaging planes to anticipate organ motion and improve treatment accuracy of MRI-guided radiation therapy. We demonstrate our framework on clinical MRI-linac treatment data.
15:08		530-03-009. UHF MRI (7T) Symbiotic QSM-DTI Tractography for Augmented Imaging Support in MRgFUS Neurosurgery Martin Ndengera, Robin Peretzke, Laura Gui Levy, Daniele Botta, Shahan Momjian, Paul Constanthin, Bénédicte Delattre, João Jorge, Pauline Guillemin, Ludovica Romanin, Gian Franco Piredda, Julian Schroers, Orane Lorton, Alma Lingenberg, Christo Bratanov, Roberto Martuzzi, Peter Neher, Pierre-Alexandre Poletti, Karl Schaller, karl-Olof Lovblad, Marc Gallay, Vanessa Fleury, Felix Kurz, Rares Salomir University Hospitals of Geneva, Geneva, Switzerland Impact: Aiming to support incisionless MRgFUS VIM thalamotomy for essential tremor, clinical 7T brain MRI was performed and reconstructed for symbiotic QSM-DTI fibre tractography. This robustly visualised the "rubral wing" of the cerebellothalamic tract pre-operatively and assessed its post-lesion status/interruption.
15:19		530-03-010. IVIg Delivery to the Motor Cortex in Amyotrophic Lateral Sclerosis Patients using a Novel MR-Guided Focused Ultrasound System Ryan Jones, Dallan McMahon, Pedro Saldanha de Castro, Yuexi Huang, Ying Meng, Benjamin Davidson, Clement Hamani, Isabelle Aubert, Lorne Zinman, Agessandro Abrahao, Nir Lipsman, Kullervo Hynynen Sunnybrook Research Institute, Toronto, Canada Impact: This study demonstrates the safety and feasibility of large-volume, feedback-controlled ultrasound-mediated BBB opening in ALS with a novel MRgFUS device, enabling targeted drug delivery to critical motor regions and informing future therapeutic applications across neurodegenerative and central nervous system disorders.
