Hemodynamic evaluation of coronary artery stenosis is indicated in patients with ischemic heart disease. For this purpose myocardial perfusion scans are performed. In our study myocardial scans were performed by selective injection of 60 to 80 muCi of (131)I-MAA in the right coronary artery and of 3 mCi of (99m)Tc-microspheres in the left coronary artery. Four views (RAO, LAO, AP, LLAT) were taken with an Anger-Camera and a computer-control-led color-coded display system (Picker Dyna-Came-ra 3C/12 and Kruppe Atlas Elektronik EPR 1100, medium energy collimator). Right and left coronary artery perfusion images were stored and two-colour image produced. Following computer processing (smoothing, normalization) the images were added and photographed in color. In comparision with scans and left-ventricular and coronary angiography the sensitivity of the nuclear medicine method was shown in cases with reduced perfusion. Therefore the perfusion scans seem to be useful in combination with angiography for the determination of therapy.
缺血性心脏病患者需要进行冠状动脉狭窄的血流动力学评估。为此要进行心肌灌注扫描。在我们的研究中，通过在右冠状动脉选择性注射60至80微居里的（131）I - MAA以及在左冠状动脉注射3毫居里的（99m）Tc - 微球来进行心肌扫描。使用安杰尔相机和计算机控制的彩色编码显示系统（Picker Dyna - Came - ra 3C/12和Kruppe Atlas Elektronik EPR 1100，中能准直器）拍摄四个视图（右前斜位、左前斜位、前后位、左侧位）。存储左右冠状动脉灌注图像并生成双色图像。经过计算机处理（平滑、归一化）后，将图像叠加并进行彩色拍照。与扫描以及左心室和冠状动脉造影相比，在灌注减少的病例中显示了核医学方法的敏感性。因此，灌注扫描似乎与血管造影联合使用对确定治疗方法是有用的。
