在急性心肌梗死(AMI)患者中,放射性核素技术在临床确定梗死面积、评估再灌注后心肌存活数量、确定静息性协同不能的梗死区域心肌活力、检测运动或药物应激时梗死区内或其周围诱发的心肌缺血等方面起着较大的作用。AMI患者出院前的应激闪烁图显示的高危险心肌灌注图像:(1)梗死区内的可逆性缺损;(2)扫描图像显示多支冠脉病变;(3)与大面积梗死一致的大的非可逆性缺损;(4)从应激至静息时的显像存在暂时性左室腔扩大;(5)应用示踪剂时,肺吸收(201)~铊((201)~Tl)增多;(6)门电路单光子发射性计算机断层显像(SPECT)
In patients with acute myocardial infarction (AMI), the radionuclide technique clinically determines infarct size, assesses myocardial viability after reperfusion, determines cardigenic activity in resting, synergistic infarct areas, and measures infarct size during exercise or drug stress Or around the induced myocardial ischemia plays a greater role. High-risk myocardial perfusion images of the AMI patients prior to discharge from the hospital: (1) reversible defects in the infarct region; (2) scanned images showing multiple coronary lesions; (3) large, consistent large infarcts (4) there is a temporary enlargement of left ventricle during imaging from stress to rest; (5) when using the tracer, the lung absorption (201) to thallium ((201) to Tl) Increase; (6) single-photon emission computed tomography (SPECT)
