[Double-indicator radionuclide study of liver metastases].

75Se-methionine as a diagnostic agent was shown to possess a varied activity as regards metastatic liver tumors which manifested themselves in a great variability: from enhanced to the absence of its incorporation in the "cold zones" detected with the help of colloid 113mIn. An analysis of the data on 63 patients with cancers of different sites with liver metastases showed that the diagnostic value of 75Se-methionine combined with colloid 113mIn reached 90%. It was concluded that 75Se-methionine could serve as a valuable diagnostic test in the detection of malignant liver tumors.
