Tailoring Large Language Models to Radiology: A Preliminary Approach to LLM Adaptation for a Highly Specialized Domain

In this preliminary work, we present a domain fine-tuned LLM model for radiology, an experimental large language model adapted for radiology. This model, created through an exploratory application of instruction tuning on a comprehensive dataset of radiological information, demonstrates promising performance when compared with broader language models such as StableLM, Dolly, and LLaMA. This model exhibits initial versatility in applications related to radiological diagnosis, research, and communication. Our work contributes an early but encouraging step towards the evolution of clinical NLP by implementing a large language model that is local and domain-specific, conforming to stringent privacy norms like HIPAA. The hypothesis of creating customized, large-scale language models catering to distinct requirements of various medical specialties, presents a thought-provoking direction. The blending of conversational prowess and specific domain knowledge in these models kindles hope for future enhancements in healthcare AI. While it is still in its early stages, the potential of generative large language models is intriguing and worthy of further exploration.
