Abstract:
In 17 patients suffering from plasmocytoma bone marrow scintigraphy (BMS), and magnetic resonance tomography (MRT) was performed. RES expansion in the extremities was found by both methods, MRT also visualized a diffuse infiltration of the marrow. In that location, cold lesions in BMS correspond to yellow marrow. In the pelvis, however, cold lesions are due to tumor involvement. Both methods offer additional diagnostic opportunities and may in the future allow to expand the time intervals between routinely performed iliac crest biopsies.
