Dear gina: In general, areas of "concern" show up as dark areas on a bone scan. Other areas that will show up darker will include the injection site, the kidneys and any area that has bone damage. Arthritis will also show up on a bone scan. A radiologist is able to differentiate between
benignBenign ear cyst or tumor
Benign positional vertigo bone damage and damage that is "concerning" or may represent cancer.
Take care, hunnyB
