通过脉冲多普勒双工超声检查对 67 名接受肾移植的患者进行了 184 次检查，并开发了脉冲多普勒指数（PDI）来提供肾脏血流模式的指标。在对可行的同种异体移植物进行所有技术上令人满意的检查期间，从移植血管获得动脉多普勒信号；当超声检查和肾图均可用时，基于 PDI 和临床功能研究的移植状态解释与放射性核素肾图诊断一致，超过 90%。脉冲多普勒分析可以区分动脉闭塞和严重排斥反应，并可以减少对某些患者进行放射性核素研究的需要。
Sixty‐seven patients who had had renal transplants were examined 184 times by pulsed Doppler duplex sonography, and a pulsed Doppler index (PDI) was developed to provide an indicator of renal blood‐flow patterns. Arterial Doppler signals were obtained from transplant vessels during all technically satisfactory examinations of viable allografts; interpretations of transplant status based on the PDI and clinical function studies agreed with radionuclide renogram diagnoses in more than 90 per cent of cases when both sonograms and renograms were available. Pulsed Doppler analysis may differentiate between arterial occlusion and severe rejection and may decrease the need for radionuclide studies in some patients.
