FactCheXcker: Mitigating Measurement Hallucinations in Chest X-ray Report Generation Models

CVPR 2025poster

Medical vision-language models often struggle with generating accurate quantitative measurements in radiology reports, leading to hallucinations that undermine clinical reliability. We introduce FactCheXcker, a modular framework that de-hallucinates radiology report measurements by leveraging an imp…

Knowledge-enhanced Visual-Language Pretraining for Computational Pathology

ECCV 2024oral

"In this paper, we consider the problem of visual representation learning for computational pathology, by exploiting large-scale image-text pairs gathered from public resources, along with the domain-specific knowledge in pathology. Specifically, we make the following contributions: (i) We curate a…

RaTEScore: A Metric for Radiology Report Generation

EMNLP 2024main

This paper introduces a novel, entity-aware metric, termed as Radiological Report (Text) Evaluation (RaTEScore), to assess the quality of medical reports generated by AI models. RaTEScore emphasizes crucial medical entities such as diagnostic outcomes and anatomical details, and is robust against co…

MedKLIP: Medical Knowledge Enhanced Language-Image Pre-Training for X-ray Diagnosis

ICCV 2023poster

In this paper, we consider enhancing medical visual-language pre-training (VLP) with domain-specific knowledge, by exploiting the paired image-text reports from the radiological daily practice. In particular, we make the following contributions: First, unlike existing works that directly process the…
