Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The diagnostic accuracy of DWI in the evaluation of disease activity in JIA as compared to contrast-enhanced MRI as the reference standard. The accuracy of DWI in detecting joint inflammation as compared to the physical examination in the evaluation of different stages of disease activity in JIA patients. | — |
Secondary
| Measure | Time frame |
|---|---|
| The correlation between DWI and semi-quantitative scores of synovial hypertrophy using the Juvenile Arthritis MRI Scoring (JAMRIS) system (at baseline and at two-year follow-up). The degree of association between DWI parameters and scores obtained from the physical examination (at baseline and at two-year follow-up). The correlation between DWI parameters and laboratory assessments of inflammatory parameters (at baseline and at two-year follow-up). The value of DWI in predicting the clinical course in 1 year time in JIA patients. The responsiveness to change of DWI parameters. | — |
