Radionuclide analysis for human species According to the radioactive isotope analysis results of the Oak ridge(橡树岭)lab: In one year, 98% of the atoms of organism (human body) is replaced. The body does not have a constant material And in certain time the materials inside bod are to produce thousands of times biological chemical reactions every second

Broadly, all the assay technologies via immune reactions by antigen and antibody which tagged by radioactive isotopes can be called RIA 广义来说,凡是应用放射性同位素标记的抗原或抗体,通 过免疫反应测定的技术,都可称为放射免疫技术。 So far has development to the fifth generation of RIA technology. It is characterised by the combination of magnetic particles and ria or IRMA (immunoradiometric assay

PET/ CT PoSitron emission tomography CT PET/CT is a perfect fusing of PET and ct. It can Provide detailed lesion function and metabolic information of moleculars by PEt, and in the same time, provide the accurate lesion anatomic localization by CT It is characterised by sensitivity, accuration specific and accurate location It is extensive used in radiotherapy, and also be called the high-tech coronal of Modern medicine
