[Interpretation of and indications for bone scintiscans].

The interpretatiton of a bone radioisotope scan requires perfect knowledge of normal skeletal appearances, shadows outside the bones and the various methods of expression of bony lesions: generally hyperfixations but sometimes isofixations or even hypofixations. A bone scan permits one to make an overall assessment of multiple bony lesions, determine the extent of a lesion, detect bony complications of a disease or treatment and seek the bony origin of a pain.
