Evaluating Large Language Models for Radiology Natural Language Processing

Abstract: The rise of LLMs has marked a pivotal shift in the field of NLP. LLMs have revolutionized a multitude of domains, and they have made a significant impact in the medical field. LLMs are now more abundant than ever, and many of these models exhibit bilingual capabilities, proficient in both English and Chinese. However, a comprehensive evaluation of these models remains to be conducted. This lack of assessment is especially apparent within the context of radiology NLP. This study seeks to bridge this gap by critically evaluating thirty two LLMs in interpreting radiology reports, a crucial component of radiology NLP. Specifically, the ability to derive impressions from radiologic findings is assessed. The outcomes of this evaluation provide key insights into the performance, strengths, and weaknesses of these LLMs, informing their practical applications within the medical domain.
