Sentence examples for predominant diffusion direction from inspiring English sources

FA increases are generally driven more by reductions in radial diffusion (RD) (in the perpendicular plane to predominant diffusion direction) than by changes in axial diffusion (AD) (in the plane parallel to predominant diffusion direction) (Giorgio et al., 2008; Lebel et al., 2008), although some studies have reported a decrease in both modalities (Eluvathingal et al., 2007).

Similar to our findings, Asato et al., found continued decreases in the diffusion measure into post-puberty, though MD reflects overall magnitude of diffusion independent of direction, whereas RD considers diffusion only in the direction perpendicular to the predominant diffusion direction.

After these processes, using DTIFit within the FMRIB's diffusion toolbox, the images were calculated to get the FA, λ1 (longitudinal diffusivity) (the magnitude of diffusion along the principal diffusion direction) and λ23 (radial diffusivity) (the magnitude of diffusion in the two orthogonal directions perpendicular to the principal diffusion direction) maps.

These facts can be attributed to changes in the predominant diffusion process as dry density increases.

The diffusion weighted images (for each diffusion direction) were then averaged, and the average set was used for further analysis.

Individual ROIs were manually defined on colour-coded maps of the main diffusion direction without thresholding.

The main diffusion direction of water molecules within tissues defines the color coding in fiber tracking.

The principal diffusion directions of both tensors are displayed.

The orientations of the 60 diffusion directions are plotted in Fig. S1.

Similarly, the number and orientation of the main diffusion directions are preserved, but, what is crucial, the information about diffusion coherence is lost.

This was calculated by averaging the values for the secondary and tertiary diffusion directions.
