Choi et al. describe a useful method for producing parametric images of myocardial blood flow from dynamic PET 13N-ammonia images of the myocardium. The method is important because it provides a convenient vehicle for quickly displaying anatomically oriented information about absolute values of myocardial blood flow in humans. Absolute values of myocardial blood flow will enhance our ability to assess relative coronary flow reserve and will make it possible to noninvasively and routinely measure absolute coronary flow reserve. In addition, absolute measurements of myocardial blood flow will be useful in addressing important clinical problems, such as myocardial viability, stunning and hibernation. We look forward to the time when technical advances make it possible to obtain accurate parametric images not only of transmural but also endocardial epicardial distribution of blood flow.
崔等人描述了一种从心肌动态PET 13N-氨图像生成心肌血流参数图像的有用方法。该方法很重要,因为它为快速显示有关人体心肌血流绝对值的解剖学定向信息提供了便利手段。心肌血流的绝对值将增强我们评估相对冠状动脉血流储备的能力,并使无创且常规地测量绝对冠状动脉血流储备成为可能。此外,心肌血流的绝对测量对于解决重要的临床问题,如心肌存活、心肌顿抑和心肌冬眠,将是有用的。我们期待技术进步能够使我们不仅获得准确的跨壁血流参数图像,而且还能获得心内膜-心外膜血流分布的参数图像。
