| Research Abstract |
After imaging processing of diffusion tensor tractography derived from the brain MRI, tractography was integrated to treatment planning software for stereotactic radiosurgery of the brain as well as neuronavigation system for microsurgery. As a result, we found that stereotactic irradiation of 10Gy to the temporal fibers of the arcuate fasciculus caused language disturbance, while that to the frontal fibers did not. If the dose to the pyramidal tract was set within 20 Gy, the optic radiation and the temporal fibers of the arcuate fasciculus within 8 Gy, and the frontal fibers of the arcuate fasciculus within 20 Gy during stereotactic radiosurgery, the rate of complication could extremely be reduced. By its integration to neuronavigation, we found linear relationship between the intensity of electrical stimulation and the distance to the pyramidal tract.
