 Abstract: the presence of a susceptibility distribution. Dynamic processes (Brownian motion) are taken into account using additionally a Monte Carlo (MC) method for the positioning of the protons. Signal decay computation inside a model of brain parenchyma was found to depend on the evaluation procedure of the signal decay. MC modeling leads to signal decay characteristics depending on geometry and blood deoxygenation inside the vessel. Intra- and extravascular signal decay contributions can be determined individually.
