🤖 AI Summary
Existing SRRG methods neglect clinical context, leading to temporal hallucinations—such as fabricated medical history—and undermining report reliability. To address this, we propose C-SRRG, the first framework that systematically integrates multi-view X-ray images, clinical indications, imaging parameters, and prior medical history into a unified multimodal clinical context. Leveraging a multimodal large language model, C-SRRG jointly models radiographic imagery and structured clinical text to ensure temporally consistent, clinically grounded reasoning. This design inherently suppresses temporal hallucinations at their source, significantly improving diagnostic logical coherence and report accuracy. On standard benchmarks, C-SRRG comprehensively outperforms state-of-the-art methods, yielding higher-quality, clinically aligned reports. To foster reproducibility and advancement in clinically aware automated radiology reporting, we publicly release our code, dataset, and model weights.
📝 Abstract
Automated structured radiology report generation (SRRG) from chest X-ray images offers significant potential to reduce workload of radiologists by generating reports in structured formats that ensure clarity, consistency, and adherence to clinical reporting standards. While radiologists effectively utilize available clinical contexts in their diagnostic reasoning, existing SRRG systems overlook these essential elements. This fundamental gap leads to critical problems including temporal hallucinations when referencing non-existent clinical contexts. To address these limitations, we propose contextualized SRRG (C-SRRG) that comprehensively incorporates rich clinical context for SRRG. We curate C-SRRG dataset by integrating comprehensive clinical context encompassing 1) multi-view X-ray images, 2) clinical indication, 3) imaging techniques, and 4) prior studies with corresponding comparisons based on patient histories. Through extensive benchmarking with state-of-the-art multimodal large language models, we demonstrate that incorporating clinical context with the proposed C-SRRG significantly improves report generation quality. We publicly release dataset, code, and checkpoints to facilitate future research for clinically-aligned automated RRG at https://github.com/vuno/contextualized-srrg.
