Due to their high sensitivity to changes in iron content, phase images and maps of R2* relaxation obtained with gradient echo techniques have been gaining popularity in the imaging of neurodegenerative diseases. However, the reproducibility of these techniques has not been investigated yet. Therefore, we determined the reproducibility of phase and R2* maps acquired with multi echo susceptibility weighted imaging and found that the intersession coefficient of variation is much smaller in phase images than in R2* maps.
