Abstract
Early detection of cancer through screening based on imaging is probably the major contributor to a reduction in mortality for certain cancers. Targeted imaging or therapy of receptors, gene therapy expression and cancer stem cells are research activities that will translate into clinical use in the next decade. The use of various contrast agents and radiotracers for cancer imaging and therapy are reviewed, as are the current limitations of ultrasound, x-ray imaging, and magnetic resonance imaging (MRI), and single-photon emission computed tomography, positron emission tomography (PET), and optical imaging. The lack of selectivity of chemotherapeutic anticancer agent also is still a serious drawback in conventional cancer chemotherapy
