A FastSurfer Database for Age-Specific Brain Volumes in Healthy Children: A Tool for Quantifying Localized and Global Brain Volume Alterations in Pediatric Patients.
Article in Brain and behavior, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
purposeMRI-based whole-brain manual segmentation methods are considered the gold standard for brain volumetric analysis, but are time-consuming and prone to human error. Automated segmentation tools like FreeSurfer can identify differences in brain volumes between healthy and non-healthy individuals. Deep-learning-based segmentation tools, such as FastSurfer, offer faster processing times, but further validation is needed, particularly in pediatric cases. This study aims to compare FastSurfer with FreeSurfer in a pediatric cohort and compare the volume estimates with previously published reference values.
methodsA multicenter cohort of 448 subjects aged 4-18 years from three centers was used to compare FastSurfer with FreeSurfer. Validation metrics, including the Dice Similarity Coefficient (DSC), relative volume differences (RVD), and intraclass correlation coefficient (ICC), were computed. Hemispheric asymmetries were assessed by calculating a hemispheric asymmetry index.
findingsThe segmentation methods demonstrated high agreement, with a mean DSC across subjects and regions of interest of 0.90 (95% CI: 0.79; 0.95), RVD of 0.3% (95% CI: -7.6%; 7.4%), and ICC of 0.87 (95% CI: 0.52; 0.94). After a visual inspection, which led to the exclusion of 12 subjects with segmentation errors, growth charts for relative volume estimates of 15 anatomical brain regions were generated, revealing varying growth patterns across ages. A potential clinical application is illustrated by plotting a patient's data on these growth charts, showing a specific atrophy pattern.
conclusionTo our knowledge, this is the first study investigating the use of FastSurfer in volumetric analysis of a pediatric population. Our findings suggest that FastSurfer is a reliable segmentation tool for pediatric data and is particularly promising for clinical practice due to its high accuracy despite rapid processing times. The morphometric data, growth charts, and code are publicly accessible.
