Abstract

A simple method for identifying the scanning level in computed tomography (CT) of the spine is described. The method involves exposing a lead lattice grid on a conventional X-ray film and taking a conventional spine film with aluminum markers on the patient's back. The film showing the grid and the markers on the patient's spine is used to localize the CT scans taken with the aluminum markers still on the patient's back.
