Contiguous bone activity

A.Prof Frank Gaillard et al.

Contiguous bone activity is a bone scan phenomenon seen in tumors which incite a regional hyperemia. Increased activity on blood pool images is seen extending across joints and to adjacent bones. This should not be mistaken for direct tumor involvement. 

An example of a tumor which may demonstrate this phenomenon is the giant cell tumor of bone (GCT).
