心肌闪烁造影是利用放射性核素~(201)鉈、~(99m)锝具有选择性的摄影,使心肌显像。~(201)鉈从生物学及物理学的特性来看,是目前最佳的心肌显像核素,广泛用于缺血性心脏病的诊断。尤其是运动负荷~(201)鉈心肌闪烁造影。由于~(201)鉈的再分布,使缺血区显像,对于一过性缺血区也有可能显示出来,这对于诊断缺血性心脏病比心电图运动负荷试验,具有高度的准确性。此种检查方法不必应用测功计和脚踏车,出现peak stress时将1.5～3毫居里的~(201)TI快速静注
Myocardial scintigraphy is the use of radionuclide ~ (201) thallium, ~ (99m) technetium selective photography, the myocardial imaging. ~ (201) Thallium is the best myocardial imaging nuclide, which is widely used in the diagnosis of ischemic heart disease from the perspective of biology and physics. Especially exercise load ~ (201) thallium myocardial scintigraphy. Due to the redistribution of ~ (201) thallium, the imaging of the ischemic area may also be shown for the transient ischemic area, which is of high accuracy for the diagnosis of ischemic heart disease than the electrocardiographic exercise load test. This test method does not have to be applied dynamometer and bicycle, peak stress occurs when 1.5 ~ 3 mill Curie ~ (201) TI rapid intravenous injection
