Role of Molecular Imaging in Oncology
Journal Title: Cancer Studies & Molecular Medicine – Open Journal - Year 2014, Vol 1, Issue 1
Abstract
Molecular Imaging (MI) is an emerging technology for the early detection of disease, staging of the disease, and for monitoring response to therapy. It also offers a non-invasive method to detect in vivo biological functions and processes at a molecular level. The use of MI requires careful selection of targeting molecules which are expressed differentially in diseased vs. healthy cells to interrogate the cell microenvironment. Targeting molecules for MI could consist of small molecules, single amino acid units, low molecular weight peptides, antibodies or antibody fragments. Over the years, a large number of small molecular weight imaging probes have been developed to target different molecular pathways using Positron Emission Tomography (PET) and Single Photon Emission Computed Tomography (SPECT). The use of high molecular weight probes such as radioactive antibodies (Ab) is also equally attractive. While a major effort is placed on developing radioactive probes for PET and SPECT imaging, an intense effort is being focused on enhancing the utility of other MI modalities such as nuclear Magnetic Resonance Imaging (MRI) and Magnetic Resonance Spectroscopy (MRS), Computed Tomography (CT), optical imaging and ultrasound (US).
