Beyond guesswork: addressing the wide variability in pediatric iodinated contrast media delivery from an international perspective.
Article in Pediatric 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
backgroundRadiographers play a crucial role in ensuring the safe and effective delivery of iodinated contrast media in pediatric CT imaging. However, practice variability across institutions, such as differences in contrast medium dosing protocols, injection techniques, and timing of image acquisition, raises concerns about consistency, patient safety, and diagnostic quality.
objectiveTo examine the range of real-world practices in pediatric iodinated contrast medium administration, focusing on protocol adherence and variations in technique. MATERIALS AND
methodsAn international cross-sectional survey was conducted among 103 CT radiographers. The online questionnaire assessed demographic data, clinical practices, protocol modification behaviors, and institutional procedures. Data were collected over 9 weeks and analyzed using descriptive and comparative statistics to identify trends and practice variability.
resultsThe findings revealed considerable variability in iodinated contrast medium administration practices, including differences in injection rates, contrast volumes, catheter gauge selection, and use of saline flush techniques. Although 93.2% of participants reported confidence in modifying contrast protocols, knowledge assessments showed that 75.7% of radiographers scored in the "Poor" category, with no participants achieving an "Excellent" score. Additionally, many respondents reported relying on experience-based practices rather than standardized institutional guidelines, contributing to inconsistent contrast delivery approaches. No significant associations were found between demographic factors and reported practices, suggesting variability exists across all levels of education and experience.
conclusionThe study highlights inconsistencies in pediatric iodinated contrast medium delivery practices among CT radiographers, emphasizing the need for standardized protocols and structured training programs. Addressing these inconsistencies is crucial for improving diagnostic quality, patient safety, and promoting consistency in best practices across clinical settings.
