Equilibrium radionuclide ventriculography was applied in 27 healthy anaesthetised dogs (9 to 60 kg) after labelling the blood pool with 99mTc, using a gamma camera with a computer on-line. Quantitative analysis of the calibrated ventriculogram provided the following left ventricular parameters: the end diastolic volume (EDV), the ejection fraction (EF), the possible degree of regurgitation and as velocity indices the peak ejection and peak refilling rates (PER and PRR). Averaged results were: EDV 1.8 ml kg-1; EF 0.59; PER 4.3 EDV s-1; PRR 3.75 EDV s-1. Visual inspection of the camera images may reveal abnormal wall motions and dilatation of heart chambers.
在给27只健康的麻醉犬（体重9至60千克）用99mTc标记血池后，使用带在线计算机的γ相机进行平衡放射性核素心室造影。对校准后的心室造影进行定量分析可得出以下左心室参数：舒张末期容积（EDV）、射血分数（EF）、反流的可能程度以及作为速度指标的射血峰值和再充盈峰值速率（PER和PRR）。平均结果为：EDV 1.8毫升/千克；EF 0.59；PER 4.3 EDV/秒；PRR 3.75 EDV/秒。对相机图像进行目视检查可能会发现异常的室壁运动和心腔扩张。
