Radionuclide bone scanning with technetium-99 (99mTc)-methylene diphosphonate (MDP/MDI) is important in evaluating for the presence of metastatic or multifocal disease (see the images below). After the bone scan, an image of abnormal areas should be obtained with computed tomography (CT) or magnetic resonance imaging (MRI).
