Pediatric brain MRI without sedation: Optimization by simulation.
Article in BMC pediatrics, 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
backgroundMRI in young children often requires general anesthesia (GA) due to distress and movement. While GA in general is considered safe, its use introduces risks and logistical challenges. Recent research indicates that simulation-based preparation using a mock MRI scanner may reduce the need for GA.
objectiveTo evaluate the role of a mock MRI scanner in preparing children aged 3–6 years for awake brain MRI scans. MATERIALS AND
methodsForty children aged 3–6 years scheduled for brain MRI under GA were recruited. Each child underwent a simulation session in a mock MRI scanner. Children who completed the simulation proceeded to awake MRI. Data on awake MRI performance, image quality, and scan logistics were collected.
resultsThirty-six children (90%) successfully completed the simulation, all of whom (100%) completed the subsequent awake MRI without GA. All awake scans were diagnostically adequate. Simulation sessions effectively identified which children could tolerate awake MRI, enabling efficient scheduling and avoiding repeat scans. The remaining four (10%) children underwent MRI under GA.
conclusionA mock MRI scanner integrated into a structured preparatory program appears to enable the use of awake MRI in children aged 3–6 years. This approach reduced reliance on GA, maintained image quality, and improved workflow and efficiency. These findings support the routine use of simulation-based preparation in pediatric radiology.
