This session showcases innovations in MR‑guided interventions, including robotic catheter navigation, biopsy and ablation techniques, adaptive motion compensation, and device performance optimization. Presentations highlight how emerging imaging methods, reconstruction algorithms, and hardware designs can improve targeting accuracy, treatment monitoring, and overall procedural safety across a range of interventional applications.

		369-06-001. Training and Validation of Magnetic Needle Models for Interventional Localization Sarah Garrow, William Grissom Case Western Reserve University, Cleveland, United States of America Impact: Metallic instruments used in MR-guided interventions can cause distortions that obscure their location and introduce treatment or biopsy error. This research is aimed toward providing more accurate and precise position information of these metallic instruments.
		369-06-002. Enabling MR-Guidance of Magnetically-Actuated Robotic Catheter Interventions Using Interleaved Imaging and Actuation Ridaa Ali, Dominique Franson, Isabella Hansen, Tobias Cowles, Daniel Herzka, Mark Griswold, Murat Cavusoglu Case Western Reserve University, Cleveland, United States of America Impact: MR-actuated robotic catheters and MR imaging each offer benefits in cardiovascular interventions. However, catheter actuation creates artifacts in MR images. This work enables MR guidance during robotic interventions by removing actuation artifacts while maintaining predictable catheter motion.
		369-06-003. MRI-Guided IPL Boost in SBRT: Impact on PSA Nadir and Kinetics Jing Yuan, Oi Lei Wong, Cindy Xue, Hiu Yi Wong, Bin Yang, Sin Ting Chiu, Darren Ming Chun Poon Hong Kong Sanatorium & Hospital, Hong Kong, Hong Kong Impact: MRI-guided IPL boosting in SBRT may reduce PSA nadir, improving biochemical control in prostate cancer. This could refine clinical protocols, guide future trials, and highlight MRI’s role in enhancing precision radiotherapy outcomes for patients.
		369-06-004. MRI-Measured Prostate Volume Change Dynamics in MR-guided Stereotactic Body Radiotherapy by ADT and Risk Stratification Jing Yuan, Chen-Yu Huang, Peixiong Li, Hiu Yi Wong, Oi Lei Wong, Cindy Xue, Bin Yang, Sin Ting Chiu, Darren Ming Chun Poon Hong Kong Sanatorium & Hospital, Hong Kong, Hong Kong Impact: MRI-measured prostate volume changes during MRgSBRT inform adaptive radiotherapy planning. Stratification by ADT and risk level enhances understanding of volume dynamics, potentially improving treatment precision and patient outcomes in prostate cancer management.
		369-06-005. Quality and performance assessment framework for interventional MR-microwave applicators Laura Bauer, Mingming Wu, Sihang Cheng, Luigi Nardone, Max Seidensticker, Olaf Dietrich LMU University Hospital, LMU Munich, Munich, Germany Impact: This study presents a quality-control workflow for assessing power delivery of medical microwave ablation systems, enabling the user to evaluate and optimize parameters such as cable-length, leading to safer and more predictable MR-guided microwave ablations.
		369-06-006. Bend and Press: RF Shielding of Braided Venous Stents at Different Configurations Lisa Regler, Simon Reiss, Kian Tadjalli Mehr, Klaus Düring, Wibke Uller, Michael Bock University Medical Center Freiburg, Faculty of Medicine, University of Freiburg, Freiburg, Germany Impact: The RF shielding of two braided venous stents at 1.5T and 3T changes when the stents are bent or compressed. Smaller shielding at 1.5T makes this field strength favorable for post-implantation imaging to diagnose vein patencies.
		369-06-007. Out-of-bore Respiratory Tracking for MRI-guided Percutaneous Interventions using a Noise Navigator Witek Bosman, Evangelia Ilia, Wyger Brink University of Twente, Enschede, Netherlands Impact: Passive thermal-noise navigation allows respiratory tracking for interventional guidance outside the bore. This offers a practical path to MR-guided abdominal interventions with full operator access without requiring any additional hardware.
		369-06-008. Feasibility of MR guided lung biopsy at 0.55T using 3D stack-of-spirals UTE Pan Su, Nathan Ooms, Florian Maier, Joshua Krieger, Bradley Bolster, Jesse Roll, Jianing Pang Siemens Medical Solutions USA, Inc., Malvern, United States of America Impact: Our study demonstrated that UTE imaging at 0.55T allowed needle visualization in lung parenchyma, potentially positioning mid-field MRI as a platform for both pulmonary imaging and interventions.
		369-06-009. TGRAPPA-Initialized Unrolled Network for Low-Latency Cine Reconstruction Developed for Interventional MRI Yixuan Liu, Yu Ding, Samuel Ting, Rizwan Ahmad, Orlando Simonetti The Ohio State University, Columbus, United States of America Impact: A TGRAPPA-initialized unrolled network with pretrained coil sensitivity estimation module achieves high-quality, low-latency cine reconstruction within 144 ms per frame. The approach removes dependence on ESPIRiT and supports robust real-time imaging for MRI-guided cardiovascular interventions across dynamically changing imaging planes.
		369-06-010. Feasibility of Using Ultrashort Echo Time (UTE) Sequences for MRI-Guided Biopsy in the Musculoskeletal System Fengxian Wang, Hongyan Zhu, Zheng Qian, Zengping Lin, Yang Yang, Le Cheng, Jun Chen Nanjing Drum Tower Hospital, The Affiliated Hospital of Nanjing University Medical School, Nanjing 210008, China Impact: This optimized ultrashort echo time (UTE) MRI sequence optimized for MRI-guided biopsy, enables precise, artifact-minimized needle localization and improved procedural accuracy, addressing a key unmet need for reliable MRI-based guidance in challenging musculoskeletal biopsy interventions.
