[MR tomography of hemophilic arthropathy of the knee joint].

The value of MR tomography in the diagnosis and follow-up of haemophilic arthropathy of the knee was studied in 40 examinations, using special surface coils. Good spatial resolution and reconstruction in various planes provide an accurate demonstration of the lesion, particularly of the intra-articular structures. Abnormalities of the synovia and of hyaline cartilage can be demonstrated. MR tomography is an important imaging method which is superior to sonography or CT in demonstrating complications resulting from the bleeding, such as effusions and haemarthroses.
