Positron emission tomography (PET) imaging has emerged
as an important clinical tool for cancer management, and specifically targeted
radiopharmaceuticals play critical roles on PET molecular imaging. Solid
cancers have highly complex and heterogeneous microenvironment, this review
focused on those microenvironmental factors such as hypoxia,
proliferation and perfusion and, accordingly, a novel test system for
validation of current and novel targeted imaging
radiopharmaceuticals. In this review, we have introduced the establishment of
cancer and metastases models in nude mice, visualization of microenvironmental
components of hypoxia, proliferation, perfusion, stroma and necrosis in cancers
and metastases for establishing the microenvironment based model system, and
validation of several radio- pharmaceuticals such as
