Summary

Magnetic resonance imaging (MRI) and arthrography of the shoulder offer similar diagnostic and therapeutic benefits for rheumatology patients. Both imaging techniques improve clinical diagnoses and patient management strategies.

Area of Science:

  • Orthopedics
  • Radiology
  • Rheumatology

Background:

  • Diagnostic technology assessment often overlooks clinical impact beyond accuracy.
  • Evaluating the impact of shoulder imaging on patient diagnosis and management is crucial.

Purpose of the Study:

  • To assess the diagnostic and therapeutic impact of shoulder magnetic resonance imaging (MRI) versus arthrography.
  • To compare the influence of MRI and arthrography on clinical diagnoses and patient management in rheumatology referrals.

Main Methods:

  • Patients with shoulder symptoms from a rheumatology clinic were randomized to MRI or arthrography.
  • Clinician diagnostic confidence and management plans were recorded pre- and post-imaging.
  • Patient management evolution and need for further imaging were tracked for at least 10 months post-imaging.

Main Results:

  • Both MRI and arthrography demonstrated comparable diagnostic benefits, including diagnosis confirmation and new diagnoses.
  • Therapeutic impact was similar between MRI and arthrography.
  • MRI showed a notable increase in the shift towards surgical intervention compared to arthrography.

Conclusions:

  • Shoulder MRI and arthrography provide similar diagnostic and therapeutic impacts for rheumatology patients.
  • While comparable, MRI may influence treatment decisions towards surgery more frequently.
