一、心肌灌注γ照相对诊断心肌梗死和心肌缺血,本法是一种无创伤性的检查方法,根据成相的结果可分为两类:一种是有功能的心肌细胞对放射性核素选择性的摄取,健康的心肌成相,而病变部位不显影。心肌对核素摄取的多少与局部心肌血流灌注量成正比,所以称为心肌灌注成相。由于血供故障,心肌细胞功能受到损伤,核素摄取减少或是不能摄取时,显影的结果是核素分布稀疏或缺损(冷区)。另一种方
First, myocardial perfusion gamma camera on the diagnosis of myocardial infarction and myocardial ischemia, this method is a non-invasive examination, according to the results of the phase can be divided into two categories: one is a functional cardiomyocyte radionuclide Selective intake of healthy myocardial phase, while the lesion does not develop. Myocardial uptake of nuclide and the amount of local myocardial perfusion is proportional to, so called myocardial perfusion phase. Due to blood supply failure, impairment of cardiomyocyte function, decrease or ingestion of nuclide uptake, development results in sparse or defective nuclide distribution (cold zone). Another party
