title: [Imaging techniques in rheumatology: magnetic resonance imaging in rheumatoid arthritis].
abstract: Magnetic resonance imaging (MRI) is currently the most modern and, at the same time, most technically advanced instrument of sectional imaging in diagnostic radiology. MRI is superior to other radiological procedures because of its excellent soft-tissue contrast, the possibility of multiplanar imaging and the missing of ionizing radiation. Exact differentiation and imaging of soft tissue and bony alterations is of significant evidence in early diagnosis and monitoring of inflammatory joint diseases, such as rheumatoid arthritis (RA). Besides securing of technical quality management, the physician's qualification in indication, conduction and evaluation of MRI plays a pivotal role. This development of MRI for rheumatological purposes needs standardized recommendations and investigation protocols, which are now summarized and presented by the rheumatologists and radiologists of the study group of "diagnostic imaging procedures" of the German Society for Rheumatology (DGRh).
