Diffusion Tensor Imaging and Tractography
In selected patients with medically refractory epilepsy, surgical treatment can render the patients seizure free or significantly reduce seizure frequency. Temporal lobe resection (TLR) for temporal lobe epilepsy (TLE) is the most commonly performed epilepsy surgery procedure. A visual field defect (VFD) due to injury to the optic radiation (OR) may occur after TLR. Diffusion tensor imaging (DT...

متن کاملWhite matter tractography using diffusion tensor deflection.
Diffusion tensor MRI provides unique directional diffusion information that can be used to estimate the patterns of white matter connectivity in the human brain. In this study, the behavior of an algorithm for white matter tractography is examined. The algorithm, called TEND, uses the entire diffusion tensor to deflect the estimated fiber trajectory. Simulations and imaging experiments on in vi...
متن کاملDiffusion tensor tractography of the limbic system.
BACKGROUND AND PURPOSE The limbic system, relevant to memory and emotion, is an interesting subject of study in healthy and diseased individuals. It consists of a network of gray matter structures interconnected by white matter fibers. Although gray matter components of this system have been studied by using MR imaging, the connecting fibers have not been analyzed to the same degree. Cerebrospi...
متن کاملDiffusion Tensor Peripheral Nerve Tractography ~ Histological Changes and Diffusion Anisotropy ~
INTRODUCTION: The standard repertoire in the diagnosis of peripheral nervous system disorders includes clinical and electrophysiological examinations, supplemented by more invasive procedures, because peripheral nerves are difficult to delineate on conventional MRI due to their poor contrast with the surrounding tissues. Recently, the visualization of peripheral nerves using MRI has been attemp...
