Anisotropic Acquisition and Analysis for Diffusion Tensor Magnetic Resonance Imaging
Diffusion tensor magnetic resonance imaging (DT-MRI) is a non-invasive imaging method for assessing the characteristics and organization of tissue microstructure. The diffusion tensor provides information about the magnitude, anisotropy, and orientation of water diffusion in biological tissues. In brain white matter, the direction of greatest diffusivity is typically assumed to be parallel to t...

DT-MRI(Diffusion Tenosr – Magnetic Resonance Imaging) tractography is a non-invasive method of tracing neuronal fiber bundles. DT-MRI measures anisotropy per pixel and provides the directional information of eigenvectors relevant for fiber tractography. Since eigenvectors in each voxel computed from DT-MRI usually contain noise, the calculated principal eigenvector direction may be different fr...

متن کاملDiffusion-weighted magnetic resonance imaging in evaluation of gastric cancer.
OBJECTIVE To investigate the role of diffusion-weighted magnetic resonance imaging (DW-MRI) in the diagnosis of gastric tumors and discuss the diagnostic importance and potential use of apparent diffusion coefficient (ADC) measurements. MATERIALS AND METHODS Beginning in March 2009, DW-MRI was added to the routine abdominal and pelvic MR examination for all patients imaged at our institution....
