Assessment of four-dimensional flow MRI for prediction of varices risk in cirrhotic patients.
Article in European radiology, 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
objectiveThis study aims to validate the application of abdominal four-dimensional flow magnetic resonance imaging (MRI) for cirrhotic patients and quantify its effectiveness in assessing the hemodynamic impacts of cirrhosis to evaluate varices.
methodsAll consecutive patients who underwent MRIs between September 2022 and June 2023 were enrolled. Groups were divided into varicose, non-varicose, and healthy groups. ANOVA and post hoc LSD-t tests were used for statistical analysis. The correlation between hemodynamic parameters and liver function grade was evaluated using Kendall's correlation coefficient.
resultsA total of 80 patients were included (53 cirrhotic, 27 healthy). Significant disparities were found in main portal vein flow (MPV-FR), splenic vein flow (SV-FR), and vessel diameters (MPV-VD, SV-VD) among the groups (p < 0.05). MPV-FR was higher in the varicose group (24.81 ± 8.52) compared to non-varicose (19.52 ± 5.07) and healthy groups (17.26 ± 5.48). The most robust assessment of variceal risk was achieved by combining the flow rates (FRs) and VDs of MPV and SV (AUC 0.83, 95% CI 0.72-0.94).
conclusionThe combined indices of FRs and VDs of MPV and SV effectively predict the occurrence of varicose veins in cirrhotic patients. KEY POINTS: Question Non-invasive prediction of variceal risk is essential for the clinical management of advanced chronic cirrhosis, yet existing clinical examinations are inadequate. Findings The effective assessment of variceal risk was achieved by combining the flow rates and vessel diameters of the main portal vein and splenic vein. Clinical relevance Four-dimensional flow MRI can reveal hemodynamic changes in cirrhotic patients and assist in identifying gastroesophageal varices, serving as a marker for varices risk prediction.
