The elution of 99Tcm from red cells and its effect on red-cell volume measurement

AUTOR(ES)
RESUMO

Technetium-labelled erythrocytes provide a satisfactory agent for the measurement of red-cell volume with the advantages that there is a low radiation dose and repeated measurements can be readily carried out. A method of labelling red cells using 99TcmO4− with a small amount of stannous chloride has been evaluated in 20 patients, and compared with measurements of red-cell volume with 51Cr-labelled erythrocytes carried out simultaneously in the same subjects.
