Figure 1.
Region of interest placement for the diffusion tensor imaging superior longitudinal fasciculus and arcuate fasciculus measures on coronal color map images. Figure-1a: To obtain superior longitudinal fasciculus, the first region of interest was placed at the level of the rostral aspect of the splenium of the corpus callosum, depicted on sagittal color map image with slice marker. Figure-1b: Bilateral green triangular shaped regions lateral to the corticospinal blue fibers on coronal color map image, representing superior longitudinal fasciculus, are encircled using a manual tracing for this region of interest. Figure-1c: For further arcuate fasciculus segmentation, a second, rectangular-shaped 30×10 pixel region of interest was placed next to the superior posterior temporal lobe on coronal color map image.
