摘要
Quantification provides the link between the concentrations of radioactivity measured in tissue and the underlying physiologic processes occurring in the organ. Although absolute quantification can be a difficult process, simplifications of these invasive techniques have been applied with some success. Any simplified model of tracer behavior must be validated against the full model to test for bias and systematic errors.
