Magnetic resonance (MR) imaging is a well established, non-invasive method in the evaluation of joint pathologies. Basically four different MR imaging techniques are used in the clinical routine: (1) conventional MR imaging of joints, (2) intravenously contrast-enhanced MR imaging of joints, (3) direct MR arthrography with intraarticular injection of contrast medium and (4) indirect MR arthrography after intravenous application of contrast medium. Additionally, a variety of new MR imaging techniques are available and currently used for clinical research. These techniques have a great potential for clinical use in the future.
