[Results of bone marrow scintigraphy in hematological diseases]

Bone marrow scintigraphy was performed in 40 patients with haematological disorders (lymphomas, multiple myeloma, myeloid leukaemia, panmyelopathy and others). Routine skeletal scintigraphy was available for comparison in 18 patients. In agreement with the literature it became evident that marrow scintigraphy can show infiltrations of the bone marrow in haematological disorders earlier than skeletal scintigraphy. Hot lesions were caused by reactive proliferation of the bone marrow such as may occur with acute inflammatory joint diseases, osteomyelitis, fracture healing or other entities. Marrow imaging demonstrated reliably the actual distribution of the functioning bone marrow, a characteristic that is important for diagnosis and staging, especially in myeloproliferative diseases.
