Abstract

While multi-modal foundation models pre-trained on large-scale data have been successful in natural language understanding and vision recognition, their use in medical domains is still limited due to the fine-grained nature of medical tasks and the high demand for domain knowledge. To address this challenge, we propose an approach called Knowledge-enhanced Auto Diagnosis (KAD) which leverages existing medical domain knowledge to guide vision-language pre-training using paired chest X-rays and radiology reports. We evaluate KAD on four external X-ray datasets and demonstrate that its zero-shot performance is not only comparable to that of fully supervised models but also superior to the average of three expert radiologists for three (out of five) pathologies with statistical significance. Moreover, when few-shot annotation is available, KAD outperforms all existing approaches in fine-tuning settings, demonstrating its potential for application in different clinical scenarios.

  • By leveraging encoders pre-trained on large unimodal datasets and occasionally fine-tuning them on available multimodal data, researchers can achieve robust performance despite the relative scarcity of multimodal data.

    “By leveraging encoders pre-trained on large unimodal datasets and occasionally fine-tuning them on the available multimodal data, researchers can achieve robust performance despite the relative scarcity of multimodal data (Wang et al., 2023a; Zhang et al., 2023).”

    Methods (Implementation details; Algorithm overview, page not available) describe initializing a text encoder from PubMedBERT and then training a visual-language model on paired chest X-rays and reports. The Discussion reports strong performance with limited labeled data for downstream fine-tuning. These passages do not establish that both encoders were pre-trained on large unimodal datasets or that the reported performance was achieved despite scarce multimodal data; Methods (Datasets, page not available) instead describes a substantial paired image–report pre-training dataset.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
