Review of three magnetic resonance arthrography related infections

Area of Science:

• Medical Imaging
• Infectious Diseases
• Radiology

Background:

• Intra-articular infections are a potential complication following invasive procedures.
• Magnetic resonance arthrography (MRA) involves injecting contrast material into a joint.
• Previous studies have not extensively detailed infection risks associated with MRA.

Purpose of the Study:

• To investigate the cause of three intra-articular infections following MRA.
• To develop strategies for reducing infection risk related to arthrogram procedures.
• To enhance patient safety in diagnostic imaging.

Main Methods:

• Retrospective case review of three patients with post-MRA intra-articular infections.
• Multidisciplinary team analysis involving radiology, infectious disease, and microbiology.
• Evaluation of procedural workflows and potential sources of contamination.

Main Results:

• Three cases of septic arthritis were confirmed post-MRA.
• A common factor identified was the preceding barium swallow study in the same room.
• Oral contamination from barium studies was proposed as the likely source of infection.

Conclusions:

• Procedural contamination is a significant risk factor for MRA-related infections.
• Implementing enhanced safety measures can mitigate the incidence of arthrogram infections.
• Interdepartmental collaboration is crucial for identifying and addressing infection sources.
