Abstract

Posteroanterior (PA) view during linear tomography of the petrous bone can easily be used in about 80% of children. This results in a 20-30 fold reduction in dosage to the lens when compared to the anteroposterior (AP) view. The dose to the lens with 6 cuts in the PA projection is less than from a single AP roentgenogram of the skull. It is strongly recommended that the PA projection be used during linear tomography of the petrous temporal bone in all children and adults whenever possible.
