Feasibility of prefronto-caudate pathway tractography using high resolution diffusion tensor tractography data at 3T.
Mapping the human brain frontostriatal pathways using noninvasive diffusion tensor imaging (DTI) has been hampered by the inadequate imaging sensitivity, poor spatial resolution, lower tensor anisotropy within gray matter, increased partial volume averaging effects and poor signal-to-noise ratio. We investigated for the first time the utility of high spatial resolution DTI-based fiber-tractogra...
متن کاملCranial nerve tractography with 3T PROPELLER Diffusion Tensor Imaging
[Introduction] Cranial nerves are small nerves that control various sensory and/or motor functions and these nerves emerge from the brainstem. Conventional anatomical scan such as T1/T2 weighed MRI is commonly used to identify these nerves, but sometimes it is difficult to track the pathways due to complex structure. To visualize complex fiber structure, Diffusion Tensor Imaging (DTI) has been ...
متن کاملDiffusion tensor imaging and tractography of the sciatic and femoral nerves in healthy volunteers at 3T
BACKGROUND The aim was to clarify the normal fractional anisotropy (FA) and apparent diffusion coefficient (ADC) values of the sciatic and femoral nerves at the level of the hip joint and to visualize the neural tracts with diffusion tensor imaging (DTI). METHODS Twenty-four healthy volunteers (12 men and 12 women, age 20-29 years) underwent DTI for visualization with tractography and quantif...
متن کاملStructure Tensor Informed Fiber Tractography (STIFT) by combining gradient echo MRI and diffusion weighted imaging
Structural connectivity research in the human brain in vivo relies heavily on fiber tractography in diffusion-weighted MRI (DWI). The accurate mapping of white matter pathways would gain from images with a higher resolution than the typical ~2mm isotropic DWI voxel size. Recently, high field gradient echo MRI (GE) has attracted considerable attention for its detailed anatomical contrast even wi...
متن کاملCombined 3T diffusion tensor tractography and 1H-MR spectroscopy in motor neuron disease.
BACKGROUND AND PURPOSE Diagnostic confidence in motor neuron disease may be improved by the use of advanced MR imaging techniques. Our aim was to assess the accuracy (sensitivity/specificity) and agreement of combined (1)H-MR spectroscopy (proton MR spectroscopy) and diffusion tensor imaging (DTI) at 3T in patients with suspected motor neuron disease regarding detection of upper motor neuron (U...
