Abstract
This project simulates magnetohydrodynamic (MHD) effects in blood and cerebrospinal fluid during high-field MREIT using a tissue-specific human head model in COMSOL. Time-dependent velocity fields generated by Lorentz-force interactions under 1.5–18.8 T were extracted and analyzed to quantify fluid motion.
These simulations provide a foundation for predicting MRI phase artifacts caused by MHD-induced flow, extending the framework of Minhas et al. to anatomically realistic conditions.
