Synopsis
In this proof-of-principle study, an image acquisition and processing pipeline was developed to assess the cortical vasculature and its surrounding tissue. To that end, a block of human brain, which included cortex and juxtacortical white matter, was scanned post-mortem at high resolution with a multi-echo GRE sequence at 9.4T. Subsequently, R2* and vessel distance maps (VDM) were computed and their layer-specific patterns analyzed.
