Automated Structured Radiology Report Generation

ACL 2025long

Automated radiology report generation from chest X-ray (CXR) images has the potential to improve clinical efficiency and reduce radiologists’ workload. However, most datasets, including the publicly available MIMIC-CXR and CheXpert Plus, consist entirely of free-form reports, which are inherently va…

CheXalign: Preference fine-tuning in chest X-ray interpretation models without human feedback

ACL 2025long

Radiologists play a crucial role in translating medical images into actionable reports. However, the field faces staffing shortages and increasing workloads. While automated approaches using vision-language models (VLMs) show promise as assistants, they require exceptionally high accuracy. Most curr…

SMMILE: An expert-driven benchmark for multimodal medical in-context learning

NeurIPS 2025poster

Multimodal in-context learning (ICL) remains underexplored despite significant potential for domains such as medicine. Clinicians routinely encounter diverse, specialized tasks requiring adaptation from limited examples, such as drawing insights from a few relevant prior cases or considering a const…

GREEN: Generative Radiology Report Evaluation and Error Notation

EMNLP 2024finding

Evaluating radiology reports is a challenging problem as factual correctness is extremely important due to its medical nature. Existing automatic evaluation metrics either suffer from failing to consider factual correctness (e.g., BLEU and ROUGE) or are limited in their interpretability (e.g., F1Che…

GenerateCT: Text-Conditional Generation of 3D Chest CT Volumes

ECCV 2024poster

"Text-conditional medical image generation is vital for radiology, augmenting small datasets, preserving data privacy, and enabling patient-specific modeling. However, its applications in 3D medical imaging, such as CT and MRI, which are crucial for critical care, remain unexplored. In this paper, w…

Improving the Factual Correctness of Radiology Report Generation with Semantic Rewards

EMNLP 2022finding

Neural image-to-text radiology report generation systems offer the potential to improve radiology reporting by reducing the repetitive process of report drafting and identifying possible medical errors. These systems have achieved promising performance as measured by widely used NLG metrics such as…
