ABSTRACT
Characterization of magnetic susceptibility artifacts is required in a wide range of MRI studies. Experiments with a 0.2T magnet and MRI simulations were used to assess the signal decay over echo time at different pixel sizes in the case of air-water interfaces. The specific experimental signal modulation which was reproduced in simulation was interpreted. Concordance between simulation and experiments should make possible further studies of magnetic susceptibility effects with more complex objects as in molecular imaging and in porous medium imaging.
