The effect of realistic geometries on the susceptibility‐weighted MR signal in white matter

Abstract

The geometry of axons affects the MR signal significantly. Literature estimates of myelin susceptibility, which are based on fitting biophysical models to the MR signal, are likely to be biased by the assumed geometry, as will any derived microstructural properties.
