Anomalous diffusion gamma-imaging model provides new information on spinal cord microstructure

Currently, Diffusion Magnetic Resonance Imaging (D-MRI) is the only means able to measure the diffusion coefficient in vivo, with a completely non-invasive modality and without requiring exogenous contrast agents. Diffusion measurement of water molecules in human tissues, as a consequence of the interactions between molecules and obstacles that hinder and or restrict their motion, gives information about size, orientation and shape of cellular structures. Conventional diffusion techniques, such as diffusiontensor imaging (DTI) [1] are based on Gaussian diffusion. ... ...
