用放射性核素心室造影(MUGA)的方法,以多普勒心动图(DE)为判断标准,作者对106名具有各种原发性心脏病患者做了研究,评价了核素心室造影在各种心脏病患者中检测瓣膜返流的正确性,探测了瓣膜返流核素心室造影指数——FAR正常范围,以及估计了对轻度瓣膜返流的诊断价值。所有病人行安静和运动核素心室造影,采用傅里叶振幅比值(FAR)做为瓣膜返流指数,同时以超声多普勒结果为标准诊断瓣膜返流。在除外瓣膜返流的患者中测定正常瓣膜返流指数,结果为:安静时1.28±0.26,运动时1.27±0.25,但变动范围很
Using radionuclide ventricular angiography (MUGA) and Doppler echocardiography (DE) as criteria, the authors studied 106 patients with various primary cardiac diseases and evaluated the effects of radionuclide ventriculography The correctness of valvular regurgitation was examined in patients with heart disease, the normal range of valvular regurgitant ventricular contrast index (FAR), and the diagnostic value of mild valvular regurgitation were estimated. All patients underwent quiet and exercise radionuclide ventriculography. The FAR was used as the index of valvular regurgitation, and the valvular regurgitation was diagnosed by the results of Doppler ultrasound. Normal valve regurgitation index was measured in patients with excluded valve regurgitation, with a mean of 1.28 ± 0.26 at rest and 1.27 ± 0.25 at exercise, but the range of change was very high
