FIGURE 5. Midsagittal MRI Slice Depicting Measurement of Head Rotation (Tilt) About the Bitemporal Axis^a.

^a The reference line (in red), used to measure head tilt, was drawn from the most anterior point of the corpus callosum to the most posterior point. This line was found to be virtually parallel to the bicommissural line (i.e., the white line drawn between the anterior commissure and the posterior commissure).
