In this abstract, the use of a multi-echo gradient-echo sequence is investigated as a way to improve the contrast-to-noise ratio for susceptibility weighted phase imaging, which is often used to assess brain iron deposition. In comparison to the standard approach using a single-echo sequence, it is shown that the use of the proposed method allows for a significant reduction of the noise contribution in the reconstructed susceptibility weighted phase image, while preserving both contrast and acquisition time.
