近年来,心放射描记测定(Radiocardiography)巳经成为核医学检查方法,它应归功于相应的放射药物和核医学仪器的飞速发展。几年前有些加速器生产的核素,纯度不够,产量不大,由于许多短寿命放射核素的生产工艺和快速标记技术的改进,现已能常规使用了。具有大功率和多种轰击粒子的医用加速器设备也扩大了短寿命和超短寿命放射核素的使用范围。这些放射核素和新合成的放射药物用于心肌显像和心肌组织功能测定,进一步为核医学对心脏的评 In recent years, Radiocardiography has become a nuclear medicine test method, which is attributed to the rapid development of corresponding radiopharmaceutical and nuclear medicine instruments. A few years ago some of the accelerators produced radionuclides that were not pure enough and did not produce much yield. The production of many short-lived radionuclides and the improvement of the rapid labeling technique are now routinely used. Medical accelerator devices with high power and multiple particle bombardments have also expanded the use of short-lived and ultra-short-lived radionuclides. These radionuclides and newly synthesized radiopharmaceuticals are used in myocardial imaging and myocardial tissue function testing, further to nuclear medicine’s assessment of the heart
