一种简单的，无创的放射性核素技术测量瓣膜反流的严重程度已经发展。该技术比较了450例LAO门控心脏血池扫描的右、左心室卒中容量指数（左、右心室舒张和收缩之间的计数变化）。在14例对照组中，左、右心室卒中指数比值接近一致（1.15±0.15 [SD]）。在26例二尖瓣和/或主动脉瓣反流患者中，该指标更大（范围1.36-5.30，平均2.44）。卒中指数比率与定性血管造影估计的反流之间的比较显示出良好的一致性（F = 45.5, p < 0.001）。门控心脏血池扫描允许无创评估瓣膜反流的严重程度。
A simple, noninvasive radionuclide technique which measures the severity of valvular regurgitation has been developed. The technique compares right and left ventricular stroke volume indices (change in counts between diastole and systole over the left and right ventricles) from 450 LAO gated cardiac blood pool scans. In 14 control subjects, the left-to-right ventricular stroke index ratio was near unity (1.15 ± 0.15 [SD]). In 26 patients with mitral and/or aortic regurgitation it was larger (range 1.36-5.30, mean 2.44). Comparison between the stroke index ratio and qualitative angiographic estimates of regurgitation revealed good agreement (F = 45.5, p < 0.001). Gated cardiac blood pool scans permit noninvasive assessment of the severity of valvular regurgitation.
