title: Indications for the use of bleomycine-Co57 in brain scanning.
abstract: The Authors report on their experience with a new radio-active tracer, Bleomycine-Co57, which was studied in 40 patients who had previously undergone brain scanning with Indium113m. The results obtained with these two different tracers are compared and the following conclusions advanced: 1) Bleomycine-Co57 is the radio-active tracer of choice in identification of cerebral metastases, especially in those cases where brain scanning with Indium113m was non-diagnostic; 2) glioblastomas evidence less uptake of the tracer than do metastases; 3) the scarce affinity of this tracer for benign tumors is stressed; 4) owing to the long half-life of this tracer, it is preferable to use it only with those subjects suspected of having a malignant neoplasia.
