Rezumat

Background:

The delayed appearance of radiographic changes limits early diagnosis of acute mandibular osteomyelitis (AMO). Computed tomography (CT) texture analysis, a radiomics-based approach, enables quantitative evaluation of bone microarchitecture and may detect early disease. To systematically evaluate the diagnostic performance of CT texture analysis in the early detection of AMO.

Methods:

A systematic review was conducted in accordance with PRISMA 2020 guidelines. Electronic databases (PubMed, Scopus, Web of Science, Embase, ScienceDirect, Cochrane Library, and Google Scholar) were searched from January 2000 to October 2025. Studies assessing CT-based texture analysis for mandibular osteomyelitis or related jawbone pathologies were included. Data extraction covered imaging protocols, feature types, analytical methods, and diagnostic outcomes. Risk of bias was assessed using the Joanna Briggs Institute (JBI) Critical Appraisal Checklist for Analytical Cross-Sectional Studies. This review was not registered in PROSPERO.

Results:

Five studies met the inclusion criteria. CT texture analysis demonstrated high diagnostic performance, with reported sensitivity, specificity, and AUC values ranging from 0.94 to 1.0 in the primary CT-based study. Consistently informative features included gray-level co-occurrence matrix (GLCM), gray-level run-length matrix (GLRLM), and gray-level size zone matrix (GLSZM) parameters. MRI-based radiomics studies supported similar discriminatory capability. The inclusion of perilesional regions improved model performance for osteomyelitis detection.

Limitations:

Evidence is limited by small sample sizes, retrospective designs, heterogeneity in imaging acquisition, segmentation methods, and a lack of standardized radiomic pipelines.

Conclusion:

CT texture analysis shows high potential for early detection of AMO by identifying microstructural bone alterations before conventional radiographic changes. Standardization and prospective validation are required for clinical translation.

Implications:

Integration of CT radiomics into diagnostic workflows may enable earlier intervention and improved outcomes in mandibular infections.
