核医学在本世纪六十年代经历了前期、中期、后期三个时期。前期多用扫描机,中期用了γ-照像机和短寿命放射性核素,同时采用计算机进行数据处理,而六十年代后期发展到体外试验、放射免疫分析法、饱和分析法等,放射性免疫分析药物现在都已“药盒化”了。在我们国家大多数医院目前都使用扫描机,和少数γ-照像机,而所使用的放射性核素大多是中短寿命的。但医用同位素是向着短寿命、低能 Nuclear medicine in the sixties of this century experienced the pre-, mid-term and post-three periods. Early use of multi-purpose scanner, medium-term use of γ-camera and short-lived radionuclides, while the use of computer data processing, and in the late 1960s developed in vitro testing, radioimmunoassay, saturation analysis, radioimmunoassay Drugs are now “kitchens”. Most hospitals in our country currently use scanners, with a few gamma cameras, and the radionuclides used are mostly short-lived. But medical isotopes are toward short life, low energy
