| Outline of Final Research Achievements |
The prediction of outcome is important when planning appropriate rehabilitation for stroke patients. Magnetic resonance diffusion tensor imaging (DTI), which enables quantitative evaluation of neural-fiber damage within the brain, is potentially useful to predict outcomes including upper and lower extremity functions, and cognitive functions and activities of daily living. Based on DTI data obtained at 2-3 weeks post stroke, neural-fiber damage was evaluated. Outcome measurements were obtained at 3-6 months poststroke. The correlations between the neural-fiber damage and outcomes were then assessed. Neural-fiber damages in the corticospinal tracts correlated with upper and lower extremity functions and activities of daily living, whereas those in the superior longitudinal tracts correlated with cognitive functions. The findings suggest that DTI can be clinically useful when predicting outcomes of stroke patients.
