[Clinical experience of bone marrow scintigraphy in cancer patients]

129 patients with various malignant tumors and 10 persons from the control group were examined by BM scintigraphy with radio-colloids. The following scintigraphic signs were associated with neoplastic bone marrow pathology: 32 patients with BM metastasis had focal or multifocal defects on BM scans, 8-localized areas of increased tracer accumulation ("hot spots"), 5-diffusely diminished tracer uptake. There were no correlations between survival and grade of peripheral expansion of tracer uptake (scintigraphic sign of hematopoietic peripheral expansion) and the probability of bone marrow BM involvement by tumor cells.
