TemMed-Bench: Evaluating Temporal Medical Image Reasoning in Vision-Language Models

🌐 Homepage | 🐱 Github | 📖 Paper

Intro

TemMed-Bench features three primary highlights.

Temporal reasoning focus: Each sample in TemMed-Bench includes historical condition information, which challenges models to analyze changes in patient conditions over time.
Multi-image input: Each sample in TemMed-Bench contains multiple images from different visits as input, emphasizing the need for models to process and reason over multiple images.
Diverse task suite: TemMed-Bench comprises three tasks, including VQA, report generation, and image-pair selection. Additionally, TemMed-Bench includes a knowledge corpus with more than 17,000 instances to support retrieval-augmented generation (RAG).

Benchmark Overview
