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 45 degrees 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 less than 0.001). Gated cardiac blood pool scans permit noninvasive assessment of the severity of valvular regurgitation.
一种用于测量瓣膜反流严重程度的简单、非侵入性放射性核素技术已被开发出来。该技术通过对45度左前斜位门控心血池扫描获得的左右心室每搏量指数（舒张期与收缩期之间左右心室计数的变化）进行比较。在14名对照受试者中，左右心室每搏指数比接近1（1.15±0.15[标准差]）。在26名患有二尖瓣和/或主动脉瓣反流的患者中，该比值更大（范围为1.36 - 5.30，平均为2.44）。每搏指数比与反流的血管造影定性评估之间的比较显示出良好的一致性（F = 45.5，p < 0.001）。门控心血池扫描允许对瓣膜反流的严重程度进行非侵入性评估。
