Dinelle, G. Grammatopoulos, S. Carsen, A. Parisien, P. Beaule Carleton University, Ottawa, Canada Impact: PET-MRI allows for the simultaneous analysis of bone and cartilage status in hips and may provide more detailed diagnosis and prognosis for FAI and osteoarthritis patients. Both T1ρ and SUV measures are indicative of worsening pain and progression of disease.
		Computer Number: 149 1520. MAGnetic Resonance Invisible Coil (MAGIC) using liquid metal for Sequential PET-MRI image acquisition. View Presentation Video M. Mayekar, J. Adams North Carolina State University, Raleigh, United States Impact: PET-MRI surface array coils contain loops and/or dipoles made of copper, which attenuate the PET radiations significantly. The presented research motivated us to ask how to estimate the gain in PET attenuation reduction for the proposed coil architecture before proceeding.
		Computer Number: 150 1521. Developing a Public Dataset for 15O-H2O PET/MRI with ASL Perfusion in Healthy Controls and Moyamoya Patients: Methods, Validation & Applications View Presentation Video B. JIANG, M. Zhao, A. Fan, M. Khalighi, G. Steinberg, G. Zaharchuk Stanford University, Stanford, United States Impact: This dataset can significantly advance neuroimaging research by enabling reproducibility studies, validating ASL imaging against PET, and supporting artificial intelligence approaches. It provides a critical resource for scientists, clinicians, and data-driven innovations.
		Computer Number: 151 1522. Multimodal fMRI, Electrophysiological, and Electrochemical Recording Reveal Dopaminergic Modulation of Connectivity Dynamics View Presentation Video T. Shnitko, G. Gong, M. Verber, S. Song, M. McFarland, R. Peng, T-W Wang, M. MacKinnon, Y-Y Shih University of North Carolina at Chapel Hill, Chapel Hill, United States Impact: This study demonstrates the development and application of novel translational approach for simultaneously acquiring fMRI, electrophysiological, and electrochemical data in a rodent model. This multimodal recording method is valuable for neuroimaging scientists studying neurochemical origins of hemodynamics and brain networks.
		Computer Number: 152 1523. Comparing List-mode and Count-Mixing Techniques for Deep Learning-Based Disambiguation of AD Radiotracers in PET/MRI View Presentation Video A. Kumar, D. Kim, B. Ho, M.
