title: [Molecular imaging in rheumatoid arthritis].
abstract: Advances in molecular biology and technical developments in the field of imaging are increasingly allowing for non-invasive visualization and quantitation of biological processes at the molecular level. Such technologies, defined as molecular imaging, promise early diagnosis and improved classification of the stage and severity of disease, objective assessment of treatment efficacy, and reliable prognosis based on so-called molecular markers. Furthermore, molecular imaging is an important tool for the evaluation of physiological and pathophysiological processes and for drug development. Various different imaging modalities are available, such as conventional radiography (CR), computed tomography (CT), nuclear imaging, magnetic resonance imaging (MRI), ultrasound (US), as well as other methods including fluorescence-based optical imaging. These methods differ with respect to resolution and their potential to gather information at the anatomical, physiological, cellular and molecular level. Therefore, the choice of the imaging modality for molecular imaging depends on the questions that need to be answered. This review discusses the potential of imaging modalities for molecular imaging in rheumatoid arthritis (RA).
