Direct MR-arthrography, using intra-articular Gadolinium or iodinated contrast, offers superior joint visualization for specific pathologies. It should be prioritized for diagnosing painful shoulders or hips in young adults and athletes when less invasive methods are insufficient.

Area of Science:

  • Radiology
  • Medical Imaging

Context:

  • Intra-articular Gadolinium injection for MR-arthrography recently approved in France.
  • MR-arthrography use may increase, necessitating guidelines for appropriate prescription.

Purpose:

  • Review technical aspects, medico-legal implications, and indications of MR-arthrography.
  • Compare indirect and direct MR-arthrography techniques.
  • Establish optimal diagnostic pathways for joint pathologies.

Summary:

  • Indirect MR-arthrography with IV Gadolinium is not recommended due to poor contrast and joint filling.
  • Direct MR-arthrography, with intra-articular Gadolinium or iodinated contrast, enhances joint visualization by expanding the joint space.
  • Direct techniques improve delineation of articular surfaces and capsule/ligamentous structures, yielding high-quality images.

Impact:

  • Direct MR-arthrography should be considered a first-line diagnostic tool for painful shoulders and hips in young adults and athletes.
  • Avoids overuse of MR-arthrography by emphasizing its use only when providing superior diagnostic accuracy over less invasive techniques.
  • Highlights the importance of judicious application of advanced imaging techniques in clinical practice.
