Can bone tumor radiology reporting systems be used in children?: a validation study for Bone-RADS and OT-RADS in MRI in the evaluation of solitary bone tumors.
Article in European radiology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesBone tumor radiology reporting systems have been developed, including Bone-RADS and OT-RADS, aimed at standardizing imaging studies' reports and guiding the management of bone lesions. This study aims to evaluate and compare the use of Bone Tumor Radiology Reporting Systems, Bone-RADS and OT-RADS, in MRI of children with solitary bone lesions. MATERIALS AND
methodsPatients younger than 18 years old who had an MRI for the evaluation of a solitary bone lesion between January 2015 and October 2025 were included in the study. Five radiologists with different expertise levels evaluated the MRI examinations. Bone-RADS and OT-RADS were assessed using both their original categorical systems and binary classification models. We assessed inter-rater reliability using Cohen's kappa and Fleiss' kappa. For both scoring systems, a binary classification was used to assess diagnostic performance.
resultsEighty patients (mean age - standard deviation/minimum-maximum: 11.95 - 3.65/4-17 years old; 66 male) were included in the study. For both Bone-RADS and OT-RADS, the overall agreement between all raters, as assessed using Fleiss Kappa, showed moderate agreement (k = 0.470, 95% CI: 0.410-0.530) and (k = 0.432, 95% CI: 0.389-0.475), respectively. The accuracy of Bone-RADS ranged from moderate to good, and OT-RADS from moderate to excellent.
conclusionBoth Bone-RADS and OT-RADS were reliable, and demonstrated high accuracy in evaluating solitary bone tumors in children. Bone-RADS has a higher level of interrater agreement, which we attributed to the guidance provided by its algorithm. OT-RADS requires knowledge of each disease due to the lack of a comprehensive lexicon and an algorithm. KEY POINTS: Question Can bone tumor radiology reporting systems, Bone-RADS and OT-RADS in MRI, be used in the evaluation of solitary bone tumors? Findings Both Bone-RADS and OT-RADS demonstrated moderate interrater agreement in the evaluation of solitary bone tumors in children. Bone-RADS revealed moderate to good accuracy, while OT-RADS revealed moderate to excellent accuracy. Clinical relevance Bone-RADS and OT-RADS were reliable and demonstrated high accuracy in evaluating solitary bone tumors in children. These bone reporting systems can be used for solitary bone tumors in children on MRI.
