Abstract

Diffusion tensor imaging allows for visualization of white matter tracts by tractography. Methodology in this new magnetic resonance imaging (MRI) varies to match the desired use. In this study, methods of creating three-dimensional (3D) tracts were tested to analyze the corticospinal tract (CST) and somatosensory tract in post-stroke patients both before and after neurorehabilitation. Using an imaging software called FSL, I was able to superimpose the fractional anisotropy brain image with the T1 MRI image and create mask where the tracts have a higher probability of being found. The software then connected the tracts, producing a 3D visualizations of the tract which I then superimposed onto a 3D brain to show the tract in space. I found that the CST had the most reliable and reproducible results. However, the somatosensory tract results varied and I could not get a concrete methodology for this tract.
