摘要：

Objective: To examine the effects of the doss reduction obtained with photostimulable phosphor computed radiography (CR) on the identification of cephalometric landmarks. Methods: Dose reductions of 50% and 75% respectively were obtained by placing three storage phosphor image plates in the same cassette. Lateral cephalograms were exposed on ten patients, Seven observers identified 14 anatomical landmarks on the images. Results: The location of anatomical landmarks on the lateral cephalograms was not effected by the decreased dose (P>0.05). Interobserver variation was the major influence. Conclusion: A dose reduction of 75% does not effect the localization of anatomical landmarks in lateral cephalograms obtained with CR.
