This session covers advanced MRI innovations including MR thermometry, ultra-high-field MRI, and 4D Flow MRI, along with emerging contrast mechanisms for multi-organ disease evaluation. Emphasis will be placed on technical principles, clinical utility, and translational applications across diverse pathologies.

		361-03-001. Absolute thermometry at 7T using semiadiabatic spectral-spatial spectroscopic imaging (SASSI): phantom results Christoph Maier, Susanna Weber, Gaurav Verma, Bili Wang, Priti Balchandani, seena Dehkharghani, Leeor Alon Bernard and Irene Schwartz Center for Biomedical Imaging, Department of Radiology, New York University Grossman School of Medicine, New York, New York, United States of America Impact: Our novel SASSI sequence for 7T absolute MR thermometry can improve the reliability of absolute MR thermometry. These findings support feasibility of quantitative brain thermography and may inform technical development as well as protocol optimization for future vivo studies.
		361-03-002. BURST for Acoustic Radiation Force Image encoding and readout (BARFI) Simran Kukran, Kristen Zarcone, Jessie EP Sun, William Grissom, Mark Griswold Case Western Reserve University, Cleveland, United States of America Impact: Using MR-BURST to visualize ARF-driven displacement instead of current MR-ARFI techniques could lead to an increase in scan speed, increase in robustness to phase artifacts, and decrease in patient exposure to ultrasound in therapeutic ultrasound treatment planning.
		361-03-003. Effects of Anesthesia and Contrast on Temperature of Pediatric Patients undergoing Brain MRI Abdul Nashirudeen Mumuni, Henry Ngura Nsoh, Eric Naab Manson, William Nabon, Samuel Yogri, Twum Barima, Mohammed Nasir Abubakari, Abdul-Salam Issahaku, Izre-Deen Osman Mohammed Abubakari, Kasiratu Haruna, David Waliwu Monte University For Development Studies, Tamale, Ghana, Ghana Impact: Anesthesia is associated with higher temperature decrease than contrast. Age and weight of pediatric patients are significantly linked with temperature decrease with anesthesia. The MRI room should therefore be conditioned to ensure safety and comfort of anesthetized pediatric patients.
		361-03-004. Construction of a PRF thermometry phantom and accompanying heating and monitoring system Susanna Weber, Christoph Maier, Gaurav Verma, George Verghese, Bili Wang, Priti Balchandani, seena Dehkharghani, Leeor Alon Bernard and Irene Schwartz Center for Biomedical Imaging, Department of Radiology, New York University Grossman School of Medicine, New York, New York, United States of America Impact: This phantom was developed as a platform for heating, temperature change reconstruction, and verification of temperature measurements using ground truth fiber-optic measurements.Our system allows for optimizing and testing of MR-thermometry sequences prior to being deployed for in-vivo applications.
		361-03-005. Ethylene Glycol Phantom Thermometry Aaron Oliver-Taylor, Fraser Hill-Casey, Thomas Hampshire, Frank Bolton, Matt Hall, Xavier Golay, Andrew Tyler, William Lloyd Gold Standard Phantoms, Sheffield, United Kingdom

Unsupervised Susceptibility Artifact Correction in MR Thermometry Using Simulation-Derived Thermal Priors Yanwu Jiang, YA CHEN, Sheng Hu, Jianqi Sun School of Biomedical Engineering, Shanghai Jiao Tong University, Shanghai 200240, China Impact: Our work demonstrates that deep learning combined with thermal physics simulation information can enable robust artifact correction and temperature field optimization in MR thermometry—offering a viable path forward in data-scarce clinical scenarios such as MR thermometry.
		361-03-007. Towards quantitative cerebrovascular reactivity (CVR) mapping with ultra-fast blood flow imaging Dinil Sasi Sankaralayam, Cuimei Xu, Jiani Wu, Teni Akinwale, Hanzhang Lu Johns Hopkins University School of Medicine, Baltimore, United States of America Impact: This work establishes real-time phase-contrast (RTPC)-MRI as a fast, reproducible, and quantitative method to measure CVR, enabling gas-inhalation-free assessment of vascular health through simple breathing manipulations, paving the way for broader clinical translation of physiological MRI biomarkers.
		361-03-008. 5ms resolution pulse transit time measured by dynamic inflow magnitude contrast MRI for intracranial pulse wave velocity Ian Driver, Melissa Wright, Hannah Chandler, Kevin Murphy Cardiff University Brain Research Imaging Centre (CUBRIC), School of Psychology, Cardiff University, Cardiff, United Kingdom Impact: Arterial stiffness is linked to aging and neurodegeneration, but much is unknown about the underlying mechanisms in intracranial arteries. This work presents key improvements in assessing intracranial arterial stiffness with inflow MRI, establishing feasibility for population and interventional studies.
		361-03-009. Rapid Gradient-Echo 7 Tesla EPI of Cardiac Pulsatility Arrival Time and Amplitude Across Arterial and Ventricular Regions Firdaus Fabrice Hannanu, Marta Bianciardi Athinoula A. Martinos Center for Biomedical Imaging, Massachusetts General Hospital and Harvard Medical School, Charlestown, United States of America Impact: Rapid gradient-echo EPI enables visualization of timing/amplitude of cardiac pulsatility across arteries and CSF spaces. These metrics describe complementary temporal/energetic dimensions of intracranial pulsatility, highlighting potential markers of tissue compliance and glymphatic drive relevant to normal aging and neurodegeneration.
