Although diffusion imaging is sensitive to tissue microstructure, biological interpretation of diffusion properties is lacking. Imaging of post-mortem brains would enable the comparison of diffusion indices (such as MD and FA) with histological samples. We present results of diffusion imaging in whole, post-mortem human brains. Diffusion properties are significantly different than in vivo and depend on post-mortem interval. However, anisotropy is partially preserved and tractography is possible.
