Preliminary validation of a web-based MRI scoring system for children with chronic nonbacterial osteomyelitis (ChRonic nonbacterial Osteomyelitis Magnetic Resonance Imaging Scoring: CROMRIS)
Authors' conclusion
The web-based CROMRIS portal developed was usable and showed substantial-moderate agreement in the total CROMRIS Activity Index total scores among experienced radiologists after self-guided learning of the atlas and video.
Study context
- Population
- Children with chronic nonbacterial osteomyelitis; MRI scored by radiologists
- Outcome
- Interrater reliability of the CROMRIS Activity Index among radiologists, by body region
Methodological detailsqualitative, user-centered design approach, web-based
- Qualitative, user-centered design approach

Performance
As reported in the abstract
Interrater reliability, CROMRIS Activity Index: excellent for clavicle, tibia, cervical and lumbar spines
> 0.9
Mean kappa of each category of bones (substantial interrater reliability; long bones and clavicle most affected by CNO)
> 0.6
