Low-dose and low-contrast computed tomography pulmonary angiography in pediatric with pulmonary embolism: a prospective study.
Article in BMC medical imaging, 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
objectiveWe evaluated the feasibility of reducing contrast agent and radiation dose in pediatric computed tomography pulmonary angiography (CTPA) while ensuring image quality. MATERIALS AND
methodsIn this prospective study, two readers assessed the computed tomography (CT) image quality (using a 5-point scale (1: undiagnosable and 5: excellent) and objective evaluation criteria (measuring CT and noise values of the left atrium and pulmonary trunk) of 116 patients who underwent pulmonary artery computed tomography angiography (CTA) from January 2023 to April 2024. independent sample t-test and Chi-square test were used to analyze and evaluate group differences.
resultFifty-eight participants were enrolled in the study group (mean age, 6.86 years ± 2.74, 30 males) and fifty-eight participants were enrolled in the control group (mean age, 6.71 years ± 2.59, 22 males). The radiation dose was significantly decreased in the study group (study group, 3.01 ± 0.24 mGy, control group 3.77 ± 1.06 mGy, p < 0.001). Overall quality was higher in control group, but displaying ability of pulmonary artery trunk and branch was higher in study group (p < 0.001).
conclusionThis study proved that a low-dose, low-contrast CTPA strategy could reduce radiation dosage by 50% and contrast agent by 20% while maintaining a satisfying image quality.
