Bone imaging and skeletal radiology in dysbaric osteonecrosis.

Twenty-nine United Kingdom deep sea divers were examined radiographically for skeletal abnormalities and also bone images were obtained using technetium-99m methylene diphosphonate. The results of the two forms of examination were compared and the use of radionuclide bone scanning was shown to be more sensitive than radiographic examination in monitoring those occupationally at risk of acquiring dysbaric osteonecrosis.
