Fig 3. Axial CT images showing VA midpoint measurements in 4 additional children with large midpoints. Magnification of all images is the same. Enlarged rather than normal VAs are used for illustration so that the relationships of the VAs to the planes are easier to see.

A, VA midpoint measures 2.8 mm.

B, VA midpoint measures 2.6 mm.

C, VA midpoint measures 2.5 mm. D, VA midpoint measures 2.3 mm.
