Fast and accurate Bloch simulations using Magnus expansions Carlos Castillo-Passi, Charles McGrath, Kareem Fareed, Jacob Blum, Daniel Ennis Stanford University, Stanford, United States of America Impact: We introduce a new mathematical approach to MRI simulation that substantially improves the accuracy and speed for RF excitation. Our method overcomes numerical limitations of existing approaches and enables reliable integration into optimization workflows through a straightforward, GPU-compatible implementation.

This could contribute to the improved quantification of disease-related changes in important tissues containing macromolecules such as collagen.
08:28		352-01-005. Highly Effective and Robust Direct Myelin Imaging using Inversion Time Resolved Interleaved Ultrashort Echo Time (TIRI-UTE) Jinil Park, Sam Sedaghat, Stefan Sommer, Lumeng Cui, Eddie Fu, Youngkyoo Jung, Kader Oguz, Hyungseok Jang University of California, Berkeley, United States of America Impact: TIRI-UTE enables robust myelin detection using IR-UTE while reducing scan time by ~3-fold through interleaved encoding and view sharing. A sliding-window scheme provides TI-resolved imaging, improving robustness to T₁ variability and achieving more reliable myelin imaging.
08:30		352-01-006.
