Objectives: To study characteristics of thalamocortical tract according to the cerebral origin. Using diffusion tensor tractography at 3.0 Tesla scanner, we attempted to characterize the morphology of thalamocortical tract in the human brain. Subjects and methods: 50 healthy subjects were enrolled in this study. Reconstructed images of thalamocortical tract in the human brain using diffusion tensor tractography at 3.0 Tesla scanner. Results: The median length of the right thalamocortical tract was 130.64 mm and the left was 123.14 mm, the average of two sides was 126.34 mm. The difference between two sides was statistically significance. The median fiber number of the right thalamuscortical tract was 401.50 and the left was 315.00 fibers, and the average of two sides was 365.50 fibers. There was a diverse branch of thalamuscortical tract: two branches (5%); three branches (25%); four branches (42%); five branches (16%); six branches (12%); in which contralateral branch for the right was 50%, equal to the left (50%). Conclusion: Using the diffusion tensor images and 3D image reconstruction technique allows to build the intuitive and accurate image of sensory thalamocortical tract, which helps to identify the morphological characteristics of the thalamus-cortical tract of healthy people without invasion. * Keywords: Sensory thalamocortical tract, Diffusion tensor tractography.
