EARLY DIAGNOSIS OF ACUTE NECROSIS OF THE FEMORAL CONDYLI (AHLBACKS DISEASE) IN MR TOMOGRAPHY

It is often difficult to diagnose acute necrosis of the femoral condyl i (Ahlback's disease) in the early stages, since it does not become ra diologically manifest until some time later. Accumulation of activity in scintigraphy can be detected early, but it is difficult to differen tiate this from other lesions of the knee joint. MR enables early diag nosis of the acute necrosis of the femoral condyli. Arthrotic lesions of the knee joint, diseased states of the mensicus and the soft parts, all of which must be differentiated from Ahlback's disease, can be ve rified or excluded with a high degree of safety by MR.
