Fig. 1. 3D measurement of cranial shape.
A. On 3D T1-weighted imaging, the maximum transverse diameter is measured from the right temporal bone to the left temporal bone in the plane passing through the PC (arrow).
B. On 3D T1-weighted imaging, the maximum anteroposterior diameter is measured from the frontal convexity to the occipital convexity in the plane passing through the AC-PC line (arrow). The maximum craniocaudal diameter is measured from the vertex to the level of the foramen magnum in the plane passing through the PC (arrowhead).
AC = anterior commissure, PC = posterior commissure
