Quantitative Susceptibility Mapping (QSM) used for microstructural assessment of white matter (WM) is very attractive at ultra high magnetic field strengths, due to the increased signal-to-noise ratio (SNR) and phase sensitivity. This allows shortening echo and repetition times and, therefore, acquisition time. Further advantages of QSM are the low flip angles used for scanning, which results in low specific absorption rates, and the B1 insensitivity of the signal phase. However, suboptimal choice of imaging parameters will result in suboptimal SNR. The purpose of this work is to find and test optimal scanning parameters for QSM of the WM at 7T.
