[Skeletal scintigraphy. Its diagnostic possibilities and indications as compared to x-ray studies].

The properties of bone-seeking nucleids in current use are reviewed and the diagnostic potentialities of skeletal scintigraphy discussed. Osseous lesions are recognized earlier on bone scans than on roentgenograms. They are more precisely delimited and the possibility of healing can be evaluated. Roentgenographic bone survey should be replaced by whole body scans, but since a positive scintigraphic finding may be caused by different osseous processes, a specific roentgenographic check is necessary. The indication for bone scanning has been widened and depends on the clinical situation or on previous X-ray findings.
