Splenic blood flow has been measured in the dog using indium labelled autologous platelets (SBFp) and compared with splenic blood flow measured with an electromagnetic flowmeter placed on the splenic vein (SVBF). The overall correlation between SBFp and SVBF was only moderately close (r = 0.54, P less than 0.01) and SBFp was about half SVBF. When expressed as a change between sequential measurements in an individual animal, the correlation between SBFp and SVBF was closer (r = 0.85, P less than 0.001). It was concluded that SBFp is a specific measure of splenic pulp blood flow and that the discrepancy between SBFp and SVBF reflects the degree of splenic blood flow bypassing the pulp.
利用铟标记的自体血小板测量了犬的脾血流量（SBFp），并将其与置于脾静脉上的电磁流量计测量的脾血流量（SVBF）进行比较。SBFp与SVBF之间的总体相关性仅为中等程度密切（r = 0.54，P < 0.01），且SBFp约为SVBF的一半。当表示为个体动物连续测量值之间的变化时，SBFp与SVBF之间的相关性更密切（r = 0.85，P < 0.001）。得出的结论是，SBFp是脾髓血流量的一种特定测量方法，且SBFp与SVBF之间的差异反映了绕过脾髓的脾血流量程度。
