[Nonbacterial osteitis: innovations in imaging : Advances in radiology and clinical management].

Background: Nonbacterial osteitis (NBO) is a rare autoinflammatory bone disease primarily affecting children and adolescents. The absence of a unified definition and standardized diagnostic criteria complicates clinical diagnosis and management.

Objectives: This study aims to systematically review the current literature regarding the definition of NBO and assess the role of imaging particularly whole-body magnetic resonance imaging (MRI) as well as the use of the radiologic index for nonbacterial osteitis (RINBO) score in diagnosis and disease monitoring.

Materials and methods: A thorough literature review was conducted, focusing on radiological methods including whole-body magnetic resonance imaging (WB MRI) and the application of the RINBO score.

Results: Whole-body MRI demonstrates high sensitivity for detecting inflammatory bone lesions and proves useful for both diagnosis and follow-up. Conventional X‑ray imaging offers additional information about structural bone damage. The RINBO score serves as a practical tool for standardizing diagnostic interpretation.

Conclusion: The combination of whole-bodyMRI and the RINBO score enables structured and reproducible evaluation of NBO. Establishing uniform diagnostic criteria remains a central goal for future research.
