Abstract
INTRODUCTION – Susceptibility weighted MR phase data provide anatomical contrast complementary to magnitude data [1-3] by directly reflecting local magnetic field changes. However, the origin of phase contrast is not yet fully understood. Sources of the phase contrast are currently attributed to magnetic susceptibility distribution [4], chemical exchange with proteins [5], electronic screening effects [6], and the magnetic architecture at the (sub-)cellular level [7]. We decoupled these components by inverting volunteer phase data of the brain that was acquired at different orientations of the head with respect to the magnetic field in order to obtain the sources and their contributions.
