本文探讨了定量γ照相肾图在功能性肾血管性高血压筛查中的准确性和可靠性。对141例近期诊断为高血压或重度高血压的患者进行了肾灌注、总肾功能和相对肾功能以及实质通过时间的测量。在15例诊断为肾血管性高血压的患者中，13例进行了肾血管造影。在所有13例中，正确预测了肾动脉闭塞或显著狭窄。先前利用静态图像、回放缓冲区和肾图的研究表明，这些方法具有优异的灵敏度，但由于假阳性结果而具有相对较低的特异性。增加计算机定量，包括测量实质通过时间，大大提高了该试验的准确性。定量肾造影术现在可以被认为是一种可靠的手段，选择病人的狭窄肾动脉经腔扩张和随访后，这一程序。
The accuracy and reliability of quantitative gamma camera renography in screening for functionally significant renovascular hypertension was investigated. Renal perfusion, total and relative renal function, and parenchymal transit times were measured in 141 patients with recently diagnosed or severe hypertension. Renal angiography was performed in 13 of the 15 patients diagnosed as having evidence of renovascular hypertension. In all 13 either occlusion or significant stenosis of the renal artery was correctly predicted. Previous studies utilizing static images, playback buffers, and renograms have shown that these methods have excellent sensitivity, but relatively low specificity because of false-positive results. The addition of computer quantitation, including measurement of parenchymal transit times, has greatly improved the accuracy of this test. Quantitative renography can now be regarded as a reliable means of selecting patients for transluminal dilatation of stenosed renal arteries and for follow-up after this procedure.
