08:15		0001. Multiparametric exchange protons using Z-Spectrum Analysis Proton (ZAP) and CEST on phantoms and human abdomen. View Presentation Video V. Malis, M. Miyazaki University of California San Diego, La Jolla, United States Impact: Combining ZAP and CEST detects not only CEST protons but a wide spectrum of exchange protons. ZAP metrics demonstrate two proton exchange environments with good sensitivity. The combined CEST and ZAP outcomes indicates a possibility of biomarkers.
08:30		0002. 2D 1H sLASER long-TE and 3D 31P chemical shift imaging at 3T for monitoring fasting-induced changes in brain tumor tissue View Presentation Video S. Alcicek, I. Divé, D. Thomas, V. Prinz, M-T Forster, M. Czabanka, K. Weber, J. Steinbach, M. Ronellenfitsch, E. Hattingen, U. Pilatus, K. Wenger Goethe University, Frankfurt/Main, Germany Impact: We report on the validation of a dedicated, multinuclear MRSI protocol with fully automated multiparametric segmentation of glioma sub-regions for monitoring cerebral, fasting-induced changes in patients with glioma.
08:45		0003. Associations Between Brain Metabolites Measured With MR Spectroscopy & Head Impacts in High School American Football Athletes View Presentation Video Z. Liu, J. Dudley, J. Diekfuss, N. Ahmed, A. Edmondson, K. Cecil, W. Yuan, T. Zuleger, A. Slutsky-Ganesh, K. Barber Foss, G. Myer, C. Fleischer Georgia Institute of Technology and Emory University, Atlanta, United States Impact: In a clinical trial of high school American football athletes evaluating MRS-quantified brain metabolites and head impacts, choline emerged as a key metric of injury, supporting the continued use of neuroimaging metrics in charactering changes after repeated head impacts.
09:00		0004. Spherical Echo-Planar Time-resolved Imaging (sEPTI) for rapid 3D quantitative T2* and susceptibility imaging View Presentation Video N. Wang, C. Liao, X. Cao, M. Nishimura, Y. Brackenier, M. Yurt, M. Gao, D. Abraham, C. Alkan, S. Srinivasan Iyer, Z. Zhou, H. Jeong, A. Kerr, J. Halda, K. Setsompop Stanford University, Stanford, United States Impact: sEPTI technique was developed with synergetic improvements in sampling, B0 estimation, eddy-current correction, and unrolled-network reconstruction, which achieves whole-brain 0.75-mm distortion-free and blurring-free T2* and QSM quantification at 3T in 90 seconds with the potentials for wide clinical applications.
09:15		0005. 3D MR fingerprinting for dynamic contrast-enhanced imaging of whole mouse brain View Presentation Video Y. Zhu, G. Wang, Y. Gu, W. Zhao, J. Lu, J. Zhu, C. MacAskill, A. Dupuis, M. Griswold, D. Ma, C. Flask, X. Yu Case Western Reserve University, Cleveland, United States Impact: This 3D MRF method enables unprecedented quantitative tracking of contrast agents throughout the mouse brain, significantly advancing our ability to study cerebrospinal fluid dynamics and potentially transforming preclinical investigation of neurodegenerative diseases and therapeutic interventions.
09:30		0006. High-Resolution, Volumetric Diffusion-Weighted MR Spectroscopic Imaging of the Brain View Presentation Video Z. Wang, B. Sutton, F. Lam University of Illinois Urbana-Champaign, Urbana, United States Impact: Our technology enabled an unprecedented capability of high-resolution, 3D metabolite-specific diffusion parameter mapping. This capability has significant potential to offer tissue-compartment- and cell-type-specific microstructural information in vivo for many clinical and neuroscience applications.
09:45		0007. Romer-EPTI: Rotating-View Motion-Robust Super-Res EPTI for SNR-Efficient Distortion-Free In-Vivo Mesoscale dMRI & Microstructure Imaging View Presentation Video Z. Dong, T. Reese, H-H Lee, S. Huang, J. Polimeni, L. Wald, F. Wang Massachusetts General Hospital, Charlestown, United States Impact: This study introduces a novel Romer-EPTI technique that addresses key challenges in in-vivo diffusion MRI acquisition to enable high-resolution dMRI at mesoscale spatial resolutions and efficient high-b-value microstructure imaging.
10:00		0008. Spatiotemporal Encoding MRI in a Portable Low-Field System View Presentation Video Y. Qiu, P. Lee, K. Dai, S. Zhong, S. Chen, C. Wang, H. Chen, L. Frydman, Z. Zhang Shanghai Jiao Tong University, Shanghai, China Impact: SPEN-based MRI provides a robust and fast acquisition approach to obtain distortion-free images at low-cost portable low field systems, thereby expanding the prospects for rapid imaging, navigation, functional and implant imaging in low-field portable MRI.
