Occipital-Temporal Sulcus (#7)
Starting Point: Most anterior high-contrast point before the temporal pole
Direction: Anterior to Posterior
Ending Point: In occipital pole; highest contrast point near midline
Notes: Is always lateral to the collateral sulcus, and generally runs parallel to it. Choose the highest contrast point nearest the temporal pole regardless of continuity. May require jumping from high contrast point to a definitive sulcus. Use the slice views to help you determine which path to take. Also, never start at any point more mesial than the starting point of the collateral. For any bifurcations, take lateral extent as long as it does not interfere with the inferior temporal. When the double parallel type occurs, always choose the most lateral. May require a jump to the highest contrast point in occipital pole.
