Raw MRI scans undergo a series of steps that correct for noise including gradient distortion correction and subject motion correction.
Unlike DTI, CSD is capable of modelling multiple tracts crossing the same region [1], a phenomenon present in 70% - 90% of white matter [2]. This includes important regions such as the visual tracts, the language tracts, and the lateral projections of hand-motor.
Using the resultant tractography, a machine-learning-based technique called structural connectivity atlasing (SCA) is applied. SCA determines parcellation locations based on their connections - including in areas where anatomy may have changed due to pathology.
