20年来,核医学(nuclear medicine)发展很迅速。近8年内,核心脏病学(nuclear cardiology)已成为一门新的学科,这是仪器大大发展的结果。如新发展的放射性示踪剂和电子计算机技术的应用。核心脏病学的优点是非入侵性而且安全,不改变可测的血液动力学参数。此法还可用在运动时作生理性测定,用习用的方法是无法作这些测定的。所有的方法,都是将专门用于所需研究器官的放射性同位素注入中央循环系统,使之经过心脏,在心脏附近用核记录照 For 20 years, nuclear medicine has developed rapidly. In nearly eight years, nuclear cardiology has become a new discipline, a result of the tremendous growth in instrumentation. Such as the newly developed radiotracers and the application of computer technology. The advantages of nuclear cardiology are non-invasive and safe and do not change measurable hemodynamic parameters. This method can also be used for physiological measurements during exercise, with the conventional method is unable to make these measurements. All of the methods are to inject the radioisotope exclusively for the organ of interest in the study into the central circulatory system, pass it through the heart, record it in the vicinity of the heart
