This contribution presents a new reconstruction technique for combining multi-channel phase images based on a dual-echo GRE acquisition. The method is applied to multichannel GRE data acquired at 9.4T with 0.4 mm isotropic spatial resolution. SHARP-processed phase images and quantitative susceptibility maps showing sections of the cerebral cortex of the occipital and temporal lobe were presented. The susceptibility contrast is, contrary to the phase contrast, local and depicts the underlying anatomy directly. Susceptibility maps varied across the cortical thickness suggesting a layer-specific contrast. Furthermore, the magnetic susceptibility of gray matter varied depending on the cortical region.
