目前所应用的同位素技术主要有两种;~(201)铊心肌闪烁显象和放射性核素心血管造影术.本文在复习文献的基础上,结合作者自己的经验,对放射性核素技术在左室肥厚和心肌病中的应用作一综述.~(201)铊显象~(201)铊显象取决于心肌与铊的结合作用.这种结合又取决于将同位素带到心肌的血流以及心肌摄取同位素的能力.心肌灌注不良或代谢活力降低的区域,例如陈旧性心肌梗塞后的疤痕区,呈现为同位素摄取缺损区,通过几个不同方位的心脏投影,可对同位素摄
At present, there are mainly two kinds of isotope techniques currently used: ~ (201) thallium myocardial scintigraphy and radionuclide cardiovascular angiography.In this paper, based on the review of the literature, combined with the author’s own experience, the radionuclide technology in the left Hypertrophy and cardiomyopathy. (201) Thallium imaging ~ (201) Thallium imaging depends on the combination of myocardial and thallium, which in turn depends on the blood flow that carries the isotope to the myocardium and The ability of the myocardium to take up isotopes. Areas of poor myocardial perfusion or reduced metabolic activity, such as the area of the scar after an old myocardial infarction, present as an isotope uptake defect that can be isotopically taken from several different directions of cardiac projection
