title: Magnetic resonance imaging of bone marrow disorders of the knee.
abstract: Bone marrow abnormalities around the knee are encountered frequently when performing MR imaging. Some of these so-called abnormalities may represent normal variations of the bone marrow contents and have no clinical significance. On other occasions, MR imaging may be the only technique that demonstrates a bone marrow lesion. Edema, osteonecrosis, infection, and tumor are entities frequently detected and assessed with MR imaging. We now, perhaps for the first time, are able to visualize and assess directly the bone marrow and its disorders. Knowledge of normal anatomy, variants, and pathologic signs coupled with meticulous imaging techniques are of paramount importance for accurate interpretation of such MR images.
