title: [Value of calcium gluconate labelled with 99mTc in the detection of intracranial tumors].
abstract: In a preliminary communication, the authors compare the success coefficients of pertechnate 99m-Tc and of a new labelled molecule: calcium gluconate 99m-Tc, in a group of 32 patients. The results obtained showed the undoubted superiority of the gluconate in comparison with the pertechnate in the detection of intracranial metestases, and in particular those of the posterior fossa. It proved equally effective as bleomycin labeled with 57-Co. Amongst the other types of tumour studies, the use of the gluconate seems to be particularly indicated for neoplasms of the posterior fossa and in those close to the base of the skull and venous sinuses, given the marked reduction in "background noise" obtained when this method is used.
