Methods and systems are provided for the automated detection and analysis of structural tissue alterations related to myelin and axons/neurons in one or more biological structures of a patients nervous system obtained from data from a medical imaging system, or the initial sensing or data collection processes such as, those that could be used to generate an image. In some embodiments, the method comprises, at a system having a memory and one or more processor for processing and displaying images of the biological structure, computationally processing at least a T1 weighted magnetic resonance image of the structure and a T2 weighted magnetic resonance image of the structure in order to analyze at least a portion of the structure of the nervous system using a plurality of stored tissue classifier elements to determine if the portion of the structure correlates with the presence of myelin. Such methods are useful for the detection of diseases associated with demyelination.
