Med-R2: Perception and Reflection-driven Complex Reasoning for Medical Report Generation

arXiv:2504.02885v2 Announce Type: replace Abstract: Automated medical report generation (MRG) is increasingly used to reduce the burden of manual reporting and for decision support. Large vision-language models (LVLMs) hold great promise for automated MRG due to their fine-grained image-text alignment and advanced text-generation capabilities. Currently, state-of-the-art MRGs primarily focus on adapting pre-trained LVLMs with direct supervised fine-tuning (SFT), a fine-tuning strategy with medical image-report pairs. However, several factors limit the performance of these LVLMs. Firstly, direc

Why this matters
Why now

The rapid advancement of Large Vision-Language Models (LVLMs) is enabling sophisticated applications in specialized domains like medical report generation, pushing capabilities beyond direct supervised fine-tuning.

Why it’s important

This development indicates a maturation of AI techniques for critical applications, potentially transforming healthcare workflows and reducing human error and burden in medical diagnostics.

What changes

The focus shifts from simple adaptation of LVLMs to more complex reasoning paradigms ('Perception and Reflection-driven') for improved accuracy and reliability in automated medical tasks.
