利用与心电图同步的闪烁照相得到的左心室时间-放射性曲线,测量收缩间期、舒张间期、射血比数和左室射血率,是评价左心室功能的简单易行的非损伤性方法。方法:病人躺在装有高分辨率低能平行孔准直器的闪烁照相机下,静脉注射25毫居里的~(99m)Tc-人血请白蛋白,用心电图R波门电路来控制γ照相
Using left ventricular time-activity curves obtained with scintigraphy synchronized with electrocardiography, systolic, diastolic, ejection ratio, and left ventricular ejection fraction are measured as simple, easy-to-use noninvasive methods for assessing left ventricular function . Methods: The patient was placed under a scintillation camera with a high-resolution, low-energy parallel-aperture collimator and intravenously injected with ~ (99m) Tc- human blood albumin of 25 millicuries. The electrocardiogram R-wave gate was used to control the gamma photography
