Overview
Other imaging studies for ossifying fibroma include bone scan, which demonstrates mild hyperemia and moderate bone uptake during healing. However, in general they are negative.[1][1]
Other Imaging Findings
Bone Scan
Ossifying Fibroma
Appearance of ossifying fibroma depends on the phase of the lesion. In general they are negative; however, mild hyperaemia and moderate bone uptake are present during healing. If extensive uptake or hyperaemia are present, then an alternative diagnosis or superimposed fracture should be considered.[1]
Non ossifying fibroma
They are metabolically active on F18-FDG-PET images.That activity, probably is independent of lesion size, varies among patients and over time, as indicated by their F18-FDG uptake on PET. [2][3][4]
Chondromyxoid Fibroma
On bone scans, the scintigraphic "doughnut sign" has been described in chondromyxoid fibroma. However, this is very nonspecific and can be seen in many other bone lesions.[5]
