Objective:

To evaluate the reliability of contrast-enhanced ultrasound (CEUS) and contrast-enhanced MRI (CEMRI) for assessing knee synovitis in juvenile idiopathic arthritis (JIA), highlighting their importance in clinical evaluation.

Key Findings:

CEUS and CEMRI demonstrated reliability in assessing synovial inflammation in JIA, with quantitative measurements providing critical insights into disease activity.

Interpretation:

Both CEUS and CEMRI are reliable imaging modalities for evaluating inflammation severity in JIA, providing valuable information for diagnosis, monitoring, and potential treatment adjustments.

Limitations:

Limited sample size and single-centre design may affect generalizability; future studies should aim for multi-centre designs to enhance external validity.
No prior studies on the reliability of CEUS in JIA were available for comparison, indicating a need for further research in this area.

Conclusion:

CEUS and CEMRI are effective tools for assessing knee synovitis in JIA, with potential implications for improving patient management and outcomes.
