无症状性心肌缺血的诊断,可从以下4个方面进行:①负荷或Holter心电图;②心肌血流;③心肌代谢;④心功能;心电图的诊断不如另3项,而其他3项却都是用核医学方法的对象。一、心肌血流的评价测定局部心肌血流的无创性方法,最多采用铊心肌显像。在运动负荷时,由静脉注射铊,可将负荷时心肌血流分布显示出来,这是诊断心肌缺血不可缺少的方法。特别是用旋转型γ照相机进行的铊—SPECT显像,可将
The diagnosis of asymptomatic myocardial ischemia, from the following four aspects: ① load or Holter electrocardiogram; ② myocardial blood flow; ③ myocardial metabolism; ④ heart function; ECG diagnosis as the other three, while the other three are It is the object of nuclear medicine. First, the evaluation of myocardial blood flow Determination of local myocardial blood flow noninvasive method, the maximum use of thallium myocardial imaging. In exercise load, by the intravenous injection of thallium, the distribution of myocardial blood flow load can be displayed, which is an indispensable method of diagnosis of myocardial ischemia. Thallium-SPECT imaging, especially with a rotating gamma camera, can be performed
