The Benefits and implementations of Diffusion tensor imaging and Neural Fiber Tractography in Brain Surgery
Background and Aim: The methods for detecting brain activation with fMRI, MRI provides a way to measure the anatomical connections which enable lightning-fast communication among neurons that specialize in different kinds of brain functions. Diffusion tensor imaging is able to measure the direction of bundles of the axonal fibers which are all aligned. Besides mapping white matter fiber tracts,...
متن کاملPre-surgical Mapping of Paediatric Motor Function and Structure using Magnetoencephalography (MEG) and Diffusion Tensor Imaging (DTI)
Introduction and Purpose: The presence of space-occupying lesions in the brain often causes the displacement of tissue from its normal location. Accordingly, surgical resection of these lesions requires a detailed understanding of the functional and structural anatomy of the adjacent tissue. Methods such as direct electrical cortical stimulation (ECS), functional MR imaging (fMRI) and magnetoen...
متن کاملFiber Tractography and Diffusion Tensor Imaging in Children with Agenesis and Dysgenesis of Corpus Callosum: A Clinico-Radiological Correlation
Background Corpus callosum is the largest commissure in human brain. It consists of tightly packed white matter tracts connecting the two cerebral hemispheres. In this study we aimed to evaluate role of fiber tractography (FT), and diffusion tensor imaging (DTI) in ped...
متن کاملDT-MRI Tractography and its Application in Cognitive Neuroscience
Recent advancement of MRI techniques and development of new methods of image analysis have allowed us to study large neural tracts within the human brain. This is based on the principle of diffusion tensor MRI that is similar to that of diffusion-weighted imaging but takes magnitude and direction of the diffusion of water into account. Using this technique we have been able to define large neur...
