摘要
The purpose of this work was to compare the measured red-cell volume (RCV) using sodium pertechnetate [RCV-Tc-99m] compared to the reference technique using sodium radiochromate [RCV-Cr-51] and to assess the influence of technetium-99 elution on the RCV-Tc-99m value. Ten patients had simultaneous measurements of RCV-Tc-99m and RCV-Cr-51. Elution of Tc-99m from red blood cells was 2.9% and led to an average overestimation of RCV-Tc-99m of 3.7%. The introduction of individual tracer elution rates in the RCV-Tc-99m calculation corrects this overestimation.
