title: The projection of the calcified pineal gland on slightly rotated AP films as a reliable landmark. A CT study.
abstract: The projection of the pineal gland between the two outer tables of the skull in the AP film has been reconstructed on the basis of the CT print of the head, with and without lateral rotation. In this experimental approach it is proven that rotation up to 5 degrees does not influence the position of the pineal gland on the AP film. The range of the normal position of the pineal in the frontal plane is defined and the normal distribution is given.
