Magnetic Resonance Imaging (MRI) has unmatched potential for planning, guiding, monitoring, controlling interventions MR arthrography (MRA) is the imaging gold standard to assess small ligament, fibrocartilage injury in joints In contemporary practice, MRA consists of two consecutive sessions: 1) an interventional session where a needle is driven to the joint space, gadolinium contrast is injected under fluoroscopy or CT guidance 2) A diagnostic MRI imaging session to visualize the distribution of contrast inside the joint space, evaluate the condition of the joint Our approach to MRA is to eliminate the separate radiologically guided needle insertion, contrast injection procedure by performing those tasks on conventional high-field closed MRI scanners We propose a 2D augmented reality image overlay device to guide needle insertion procedures This approach makes diagnostic high-field magnets available for interventions without a complex, expensive engineering entourage
