Molecular imaging of the immune system: Uncovering the dynamics of T cell trafficking in vivo by positron emission tomography.

Positron emission tomography (PET) gene expression imaging is a new technology permitting noninvasive, longitudinal observation of cell populations in living animals. The ability to apply PET technology to image the immune system noninvasively will greatly improve the dimension of the current knowledge for understanding the dynamics of immunology. In this dissertation, we foc..
