- These statistics relate to the histograms in Figure 7 of the voxel-wise comparison of ST and DTI determined sheetlet putative normal orientations to the FI normal for the lateral ROI (left) and for the septal ROI (right). ; a – scan # as defined in Table 1; NA: Not Applicable; FLASH: fast low angle shot; ST: structure tensor of FLASH data; DTI: diffusion tensor magnetic resonance imaging; T1W is T1-weighted FLASH; n-dir: number of diffusion directions; ROI: region(s) of interest. FI: FLASH isosurface data; DTW: derivative template width STW: smoothing template width. The symbols for vectors and derived angles are defined in Table 2.
