Diffusion tensor imaging distortion correction with T 1
Introduction Diffusion weighted single shot spin-echo planer imaging (DW-EPI) is commonly used for diffusion tensor imaging (DTI). DW-EPI is very sensitive to static magnetic field (B0) inhomogeneities (such as that near air-tissue boundary) that produce geometric distortion, primarily along the phase-encoding direction. As a result, artifacts are severe in the frontal and temporal lobes due to...
متن کاملComprehensive Geometric Distortion Correction for Diffusion Tensor Imaging at Ultra-High Field
EPIs (I-IIa), corresponding FA maps without (I-IIb), with eddy-correction (I-IIc and I-IId) and the final FA maps with comprehensive distortion correction (III): For comparison, eddy correction was performed with the proposed calibration method (c) and FSL (d) and the results were compared with an reference image without distortion (IIIa). To verify the correction quality more easily, the enlar...
متن کاملHigh-resolution diffusion tensor imaging of the brain stem at 3 T.
Diffusion tensor imaging with 1.8-mm isotropic resolution was performed to delineate structures of the brain stem. High-resolution single-shot imaging was achieved by the combination of a high-field magnet (3T) and the SENSitivity Encoding (or SENSE) parallel imaging technique. Various structures in the brain stem, such as the inferior olivary nuclei, deep cerebellar nuclei, some cranial nerves...
متن کاملGeometric statistical processing of brain diffusion tensor images
Nowadays, the functioning of the human brain is still one of the biggest mysteries of humanity. The multiple holes in the understanding of the human brain explain why an intensification of brain-oriented research can be observed since a few years. One of the most recent techniques to better understand the brain is Diffusion Tensor Imaging (DTI), a noninvasive imaging modality that provides info...
متن کاملCharacterization, prediction, and correction of geometric distortion in 3 T MR images.
The work presented herein describes our methods and results for predicting, measuring and correcting geometric distortions in a 3 T clinical magnetic resonance (MR) scanner for the purpose of image guidance in radiation treatment planning. Geometric inaccuracies due to both inhomogeneities in the background field and nonlinearities in the applied gradients were easily visualized on the MR image...
