 Abstract: Effects due to susceptibility differences of different tissue types scale with the static magnetic field B0. They cause local magnetic field variations ΔB0 which lead to shorter T2* values as well as larger variations of the image phase [1]. Both effects can be used to obtain a contrast in magnetic resonance images, which profits from a higher static magnetic field. This is especially useful since regular gradient echo (GRE) sequences yield a decreased grey matter - white matter contrast for ultra-high field strength. Therefore phase images [2] and T2* maps could supplement magnitude images for differentiating different tissue types in the brain. In this work, detailed T2* maps and phase images in the human brain were acquired at 9.4 T, which show excellent tissue contrast, and demonstrate internal structures in white and grey matter.
