Medical report generation (MRG) is a task that involves automatically generating accurate and coherent captions for medical images. However, the scarcity of labeled medical image-report pairs poses challenges in developing deep and large-scale neural networks capable of harnessing the power of artificial general intelligence. In this work, the authors propose customizing off-the-shelf general-purpose large-scale pre-trained models, known as foundation models (FMs), in computer vision and natural language processing for MRG. The authors introduce their encoder-decoder based MRG model which utilizes a lightweight query Transformer to connect two FMs: EVA-ViT-g, a giant vision Transformer; and ChatGLM-6B, a bilingual large language model trained to align with human intentions. They conduct ablative experiments on the trainable components of the model to identify crucial factors for effective transfer learning. The findings demonstrate that unfreezing EVA-ViT-g to learn medical image representations and parameter efficient training of ChatGLM 6B to capture writing styles of medical reports are essential for optimal results. The authors participated in the ImageCLEFmedical Caption 2023 Caption Prediction Task competition and achieved impressive rankings based on BERTScore and ROUGE 1 metrics. This highlights the effectiveness of their approach in generating high quality medical captions. In related works, previous research on medical report generation has mainly focused on improving cross modal alignment between images and reports through reinforcement learning, architecture design or explicit loss constraints. Other approaches explore retrieval and knowledge augmented report generation but these methods are limited by the small number of labeled pairs available for training. The adaptation of foundation models has become a research hotspot in computer vision and natural language processing. Techniques such as prompt engineering aim to influence the behaviors of language models by providing them with task related priors or examples while another popular technique is parameter efficient transfer learning. Overall this work presents a novel approach to medical report generation by leveraging off the shelf foundation models and customizing them for the task. The experimental results demonstrate the effectiveness of their model in generating accurate and coherent medical captions showcasing its potential for addressing challenges in this field.

Medical report generation (MRG) is the process of creating captions for medical images automatically. It can be difficult to develop MRG models because there are not enough labeled image-report pairs available. The authors of this study suggest using pre-trained models called foundation models (FMs) and customizing them for MRG. They created a model that connects two FMs, one for vision and one for language, using a lightweight query Transformer. Unfreezing the vision FM and efficient training of the language FM are important for good results. The authors did well in a competition based on certain metrics. Previous research on MRG has focused on different techniques and approaches, and foundation models are popular in computer vision and natural language processing. This work presents a new way to do MRG by customizing foundation models, and it showed good results in experiments."
