Abstract:
Bone marrow scintigraphy, including radionuclide angiography in a 66-year-old woman with spontaneous osteonecrosis of the medial femoral condyle, showed a marked increase in radiocolloid uptake in the affected condyle. Radiocolloid uptake (reflecting phagocytic activity at the osteonecrotic lesion) was correlated with findings on roentgenography, three-phase bone scintigraphy, and magnetic resonance imaging.
