Quantitative T2 measurements in magnetic resonance imaging (MRI) can provide information about water environments in biological structures. T2 relaxation arises from spin interactions between protons and the rates are dependent on the biological environment; for example, different structures in the brain will give rise to different T2 times. Multiple water environments found in individual structures will result in a distribution of T2 times and this can be used to probe the nature of different structures. One such structure is the corticospinal tract, which gives rise to a unique T2 distribution that can be distinguished from other brain structures. In this work, T2 distribution in brain structures were investigated in an attempt to better understand the unique nature of the corticospinal tract and the differences in myelination across brain structures. Examination of healthy normal tissue is important as a basis of comparison for pathological tissue.
