Deep learning for fast screening and localization of spinal dural arteriovenous fistulas to enhance clinical workflow.
Article in NPJ digital medicine, 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
Manual processing of spinal CTA images for detecting dural arteriovenous fistulas (SDAVF) is laborious and operator-dependent. We developed an automated AI system (SDAVFdoc) that integrates a 3D convolutional neural network with anatomical prior knowledge to both identify SDAVF and localize the fistula site in a multicenter study of 718 patients. The system sequentially segments spinal structures, localizes the fistula region using anatomical priors, and finally classifies SDAVF likelihood via DenseNet within the foramina. The draining vein cluster segmentation model, using a threshold of 42.5, achieved high accuracy in distinguishing SDAVF cases, with F1-scores ranging from 0.932 to 0.960 across test sets. The DenseNet-based fistula detection model showed a high AUC of 0.928-0.954 across test sets. Compared to technicians, the system reduced processing time from 40.75 ± 11.57 min to 1.05 ± 0.29 min (P < 0.001) and clicks from 761.80 ± 202.05 to 9.68 ± 2.12 (P < 0.001), greatly streamlining clinical workflows. This AI-driven approach enables fast, accurate screening and localization of SDAVF.
