Hidden workload in pediatric radiology: a 20-year retrospective time-trend study of the increasing number of images per study.
Article in Pediatric radiology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundWorkload among pediatric radiologists is rising, driven by staff shortages, case complexity, and call demands. Higher imaging volumes are linked to diagnostic errors and job dissatisfaction, affecting patient care and radiologists' retention and recruitment. Technological advances may have increased the number of images generated per study, contributing a hidden workload not captured by study counts alone.
objectiveTo determine the increase in the number of images per study in pediatric ultrasound (US), computed tomography (CT), and magnetic resonance (MR) at a pediatric tertiary care hospital between 2004 and 2023. MATERIALS AND
methodsA single-center retrospective review was conducted on the number of images acquired in select US, CT, and MR studies for patients under 18 years during the week of June 1-7, from 2004 to 2023. Trends were assessed with linear regression, with statistical significance at a P-value of <0.05.
resultsA total of 1,751 studies were reviewed and 749,152 total images were analyzed. The average number of US images per study increased from 38.67 to 165.24, MR from 185.62 to 1,292.00, and CT from 42.53 to 266.00. Regression analysis indicated statistically significant increases in all modalities: US by 7.41 images per year, MR by 51.60, and CT by 22.27 (P<0.0001 for all). Stratification based on study subtype was also performed.
conclusionThe number of images per study has significantly increased over the two decades, adding hidden strain on pediatric radiologists' workload. Imaging protocols should be reviewed to optimize the number of acquired images without losing diagnostic accuracy.
