CT of dry skulls with craniofacial deformities: accuracy of three-dimensional reconstruction.

Dry skulls from patients with Crouzon syndrome or orbital neurofibromatosis were studied using three-dimensional reconstruction of computed tomography data. The images were compared with one another and with the actual skulls. It was concluded that the use of dry skulls is helpful in pointing out errors of inclusion or exclusion. Thinner sections permit more accurate representation. Since reconstructed data do not appear to be significantly enhanced by using overlapping sections, radiation can be reduced by using abutting sections.
