[Magnetic resonance arthrography]

Magnetic resonance (MR) arthrography is a sensitive examination technique. In this institute the majority of MR arthrography examinations are carried out on the shoulder (57 %), followed by hand (24 %) and hip joints (16 %). The use of MR arthrography is superior to native MR imaging (MRI) particularly for detection of partial thickness tendon tears of the shoulder joint. Nevertheless, this technique is invasive, time-consuming and may be uncomfortable for patients. This article summarizes the indications, risks and contraindications of MR arthrography, highlights the puncture technique and illustrates possible pitfalls.
