Fractional anisotropy (FA) is a scalar measure of diffusion anisotropy pattern in the tissue and ranges between 0 (fully isotropic diffusion ... to exclude the low-quality voxels (eg, voxels with ...

For each participant, T1-weighted (T1w) and T2-weighted (T2w) structural images (0.7mm isotropic voxels) and functional images (2mm isotropic voxels; TR=720ms) were acquired on the HCP’s customized ...

Abstract: High-resolution diffusion imaging with submillimeter isotropic voxels requires long scan times that are usually clinically impractical. Even with those long scans, the image quality can ...

The transcranial simulation function has been tested on input images with 1 mm isotropic voxels and the simulated pressure field is based on a free-field simulation at 20 W/cm 2 using the CTX-500-4 ...

Finally, these ROIs were eroded by one voxel to prevent partial volume effects and were resampled to the QSM voxel resolution (1 to 1.2 mm isotropic voxels). Due to significantly higher iron ...

2013). The scanner was customized with a gradient coil and gradient power. Each subject has 2 T1w and 2 T2w scans with 0.7 mm isotropic voxels, which were used to reconstruct high-resolution cortical ...

Tristructural isotropic (TRISO) particle fuel has long been used in high-temperature gas-cooled nuclear reactors, but it is seeing a resurgence as a result of other applications. Modern TRISO fuel ...

Coronal high-resolution MRI images of the human cerebellum. Short- and long-TE 9.4-T scans with 0.19-mm-wide isotropic voxels were combined and filtered to reconstruct the cerebellar gray/white ...

The use of microscopic computed tomography to assess the key functional parameters of systolic emptying or diastolic filling in small animals has not been previously reported. The aim of the study was ...

DTI data were acquired using echo-planar imaging (EPI; TR = 7900 ms; TE = 102 ms; 2.2 mm 3 isotropic voxels; 55 axial slices). Parallel acquisition (GRAPPA) was used with at an acceleration factor of ...

as well as for multiple diffusion orientations at voxels where the axon fibers cross or split. However, in the best of our knowledge, all the available methods are unable to estimate the an isotropic ...
