A visually grounded language model for fetal ultrasound understanding.
Article in Nature biomedical engineering, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Freehand fetal ultrasound examinations require substantial clinical skill. Here we propose Sonomate (mate of a sonographer), an AI assistant to a user during fetal ultrasound examinations. Sonomate is based on aligning video features and text features derived from transcribed audio to facilitate real-time interactions between an ultrasound machine and a user. Our approach combines coarse-grained video-text alignment with fine-grained image-sentence alignment to build a robust visually grounded language model capable of understanding fetal ultrasound videos. To tackle the challenges associated with heterogeneous language and asynchronous content in real-world video-audio pairs, we design the anatomy-aware alignment and context label correction in the fine-grained alignment. Sonomate is effective at anatomy detection in fetal ultrasound images without the need for retraining on manually annotated data. Furthermore, Sonomate shows promising performance in visual question answering for both fetal ultrasound images and videos. Guardrails are built to ensure the safety of Sonomate during deployment. This advancement paves the way towards AI-assistive technology being used to support sonography training and enhanced diagnostic capabilities.
