The proposed model describes in a quality way the process of tumor-imaging radiopharmaceuticalTc99m-MIBI distribution with taking into account radiopharmaceutical accumulation, elimination, and radioactive decay. The dependencies of concentration versus the time are analyzed. The model can be easily tested by the concentration data of the radioactive pharmaceuticals in the blood measured at early time point and late time point of the scanning, and the obtained data can be used for determination of the washout rate coefficient which is one of the existing oncology diagnostics methods.

Radioactivity and Nuclear Reactions gives an overview of nuclear chemistry with emphasis on radioactive decay, binding energy and nuclear stability. Modes of radioactive decay are discussed, along with writing and balancing nuclear equations. Decay modes covered include alpha emission, beta emission, gamma emission, positron emission, and electron capture, along with a summary of how each type of decay process affects the parent radioisotope and determines the daughter isotope formed. Nuclear transmutation induced by changes in the nuclei is discussed. The chapter covers the kinetics of radioactive decay including the relationship between the half-lives of radioisotopes and radioisotopic dating. The chapter concludes with a quantitative coverage of the energy of nuclear reactions including the interconversion of mass and energy via the mass defect.
