title: The clinical role of skeletal scanning.
abstract: Malignant disease very often spreads to the skeleton. This is particularly true for carcinomas of the breast, the lungs, the prostate, and the thyroid. Knowledge of the state of the skeleton in these disorders is therefore desirable since patient management will largely depend on the early detection of bony deposits. Primary bone disease often spreads to soft tissue (lungs), and the early detection of this may alter significantly the therapeutic approach to the primary lesion. Traditionally, X-ray skeletal surveys and serum enzyme measurements provide indices which can be used in the staging of these disorders. Complementary techniques such as mammography, xeroradiography, thermography, and radionuclide imaging have been used to provide further relevant information. A number of benign bone diseases need early assessment in order to institute the best form of treatment. It is of importance to assess the circulation in localized areas of bone and to predict the appearance of avascular necrosis, to understand the healing mechanisms involved in fractures, and to predict the outcome of bone grafting. In this paper the clinical role of bone scanning is reviewed, particular attention being given to the recent advances brought about by the introduction of the 99mTc compounds. It is important that the non-specialist should be aware of the great improvement in the results obtained and in the help they can give him in deciding on the best management of each patient as an individual.
