To determine whether real-time color coding enhances the detection of myocardial perfusion through the use of echocardiographic contrast agents, we used a recently developed real-time color system during contrast injection in six open-chest dogs. Small amounts of echocardiographic contrast were injected into the left atrium. Short-axis epicardial images were obtained with a 5-MHz transducer before and after left anterior descending artery ligation. Gray-scale and rainbow-color map images were obtained for each contrast agent. The color map allowed detection of small increments in echo intensity that were not evident with routine gray-scale imaging. Thus, real-time color coding may improve the detection of myocardial perfusion with echocardiographic contrast agents.
为了确定实时彩色编码是否能通过使用超声心动图造影剂增强心肌灌注的检测，我们在六只开胸犬的造影剂注射过程中使用了一种最近开发的实时彩色系统。将少量超声心动图造影剂注入左心房。在左前降支动脉结扎前后，用5兆赫换能器获取短轴心外膜图像。对每种造影剂获取灰度图和彩虹色图图像。彩色图能够检测到常规灰度成像中不明显的回声强度的微小增加。因此，实时彩色编码可能会改善超声心动图造影剂对心肌灌注的检测。
