title: [Accuracy of computed tomographic densitometry in the neighborhood of the pelvic bones].
abstract: A phantom is described which makes it possible to correct for the change in CT values produced by soft tissues; these can be treated quantitatively. As a result of beam hardening, artefacts are produced in the soft tissues which may be hypodense or hyperdense. Rules have been established for routine densitometry in clinical use.
