Update report on the quality of gliomas radiomics: An integration of bibliometric and radiomics quality score.

Background: Despite the increasing number of publications on glioma radiomics, challenges persist in clinical translation.

Aim: To assess the development and reporting quality of radiomics in brain gliomas since 2019.

Methods: A bibliometric analysis was conducted to reveal trends in brain glioma radiomics research. The Radiomics Quality Score (RQS), a metric for evaluating the quality of radiomics studies, was applied to assess the quality of adult-type diffuse glioma studies published since 2019. The total RQS score and the basic adherence rate for each item were calculated. Subgroup analysis by journal type and research objective was performed, correlating the total RQS score with journal impact factors.

Results: The radiomics research in glioma was initiated in 2011 and has witnessed a surge since 2019. Among the 260 original studies, the median RQS score was 11, correlating with a basic compliance rate of 46.8%. Subgroup analysis revealed significant differences in domain 1 and its subitems (multiple segmentations) across journal types (P = 0.039 and P = 0.03, respectively). The Spearman correlation coefficients indicated that the total RQS score had a negative correlation with the Journal Citation Report category (-0.69) and a positive correlation with the five-year impact factors (0.318) of journals.

Conclusion: Glioma radiomics research quality has improved since 2019 but necessitates further advancement with higher publication standards.
