We proposed a simple parameter, the kidney-to-aorta ratio (KAR), for evaluation of renal transplant perfusion. KAR was calculated from the peak counts of the kidney and the aorta. The calculated values were compared with the visual interpretation of the radionuclide first-pass flow study, percent renal uptake (%RU), and tubular extraction rate (TER) by Bubeck's one point sampling method in 37 studies. KAR correlated well with the visual interpretation of the flow study and the other quantitative parameters. Representative cases, which showed the usefulness of KAR for the objective assessment of the perfusion status of renal transplants, were presented. In conclusion, KAR is a simple and practically useful parameter for objective evaluation and follow-up of renal transplant perfusion.
我们提出了一个简单的参数——肾主动脉比（KAR），用于评估肾移植灌注情况。KAR由肾脏和主动脉的峰值计数计算得出。在37项研究中，将计算值与放射性核素首过血流研究的视觉解读、肾摄取百分比（%RU）以及通过布贝克单点采样法得出的肾小管提取率（TER）进行了比较。KAR与血流研究的视觉解读及其他定量参数具有良好的相关性。文中展示了一些代表性病例，这些病例显示了KAR在客观评估肾移植灌注状态方面的实用性。总之，KAR是一个简单且实用的参数，可用于肾移植灌注的客观评估和随访。
