title: Extraosseous Findings on Bone Scintigraphy Using Fusion SPECT/CT and Correlative Imaging.
abstract: OBJECTIVE
  Extraosseous radioactivity outside of the expected biodistribution is often encountered on (99m)Tc-methylene diphosphate (MDP) bone scintigraphy, and proper interpretation requires an understanding of the mechanisms underlying this uptake and knowledge of the possible causes, depending on the site or structure involved.
  
  
  CONCLUSIONS
  We present examples of extraosseous radiotracer uptake seen on (99m)Tc-MDP bone scans in which either SPECT with integrated CT or correlative imaging improved the study's interpretation.
