Scintigraphy, using (99m)Tc diphosphonate, has the potential for diagnosing osteonecrosis before irreversible changes are visible in routine roentgenograms. If obtained within weeks of an avascular insult, a cold area will appear on scintiscan. However, months later, the revascularization and reparative processes of the dead bone produce a hot area on scintiscan. This resulted from a study on 170 patients.
