Augmented reality navigated interventional magnetic resonance (MR) imaging can help to overcome a fundamental limitation of MR arthrography, namely the spatial separation of the two interdependent procedures of intra-articular injection of a Gadolinium-based contrast agent and diagnostic MR imaging of the respective joint. Our study shows that the novel augmented reality Image-Overlay System provides accurate and reproducible MR imaging guidance for successful shoulder and hip arthrography in human cadavers, supporting further evaluation with clinical trials.
