Three-phase radionuclide bone scanning was performed in patients with algodystrophy or osteonecrosis. This method is used to improve the specificity of ordinary bone scan. It explores vascularization and blood pool, then bone uptake in two symmetrical articulations. Non-focal hyperaemia and late diffuse uptake are in favour of algodystrophy, whereas a distinct focal hypervascularization and late uptake predominant in the femoral condyle area seem to be in favour of pre-radiological osteonecrosis.
