应用放射性核素对心脏功能进行测定,早在1927年Blamgart便进行了探索。1948年,Prinzmetal描述静脉注射示踪剂,可以在心前区获得时间～放射性曲线(即心放射图)。此后,Folse对此作了进一步改进,利用碘化钠晶体探头得到弹丸通过心脏的图像。1974年,Steele便成功地应用心放射图来计算心输出量(CO)、肺血容 The use of radionuclides to measure cardiac function was first explored in 1927 by Blamgart. In 1948, Prinzmetal described intravenous tracer, can be in the precinct to obtain the time ~ radiation curve (ie, cardiac radiograph). Since then, Folse has made further improvements, the use of sodium iodide crystal probe projectile through the heart of the image. In 1974, Steele successfully applied cardiac radiographs to calculate cardiac output (CO), pulmonary blood volume
