ViX-Ray: A Vietnamese Chest X-Ray Dataset for Vision-Language Models

ViX-Ray is the first publicly available Vietnamese chest X-ray dataset designed for vision-language model (VLM) research in medical AI. It pairs radiographic images from Vietnamese patients with expert-written clinical annotations in Vietnamese, directly addressing the lack of Vietnamese medical data in existing VLMs.

Dataset Overview

Each sample contains a PA-view chest X-ray image paired with Vietnamese-language radiology reports written by certified radiologists. All Protected Health Information (PHI) has been removed; clinically relevant metadata (age, gender) is retained. The dataset was collected under Institutional Review Board (IRB) approval.

Splits

Split	Samples	Percentage
Train	4,320	80%
Val	540	10%
Test	540	10%
Total	5,400	100%

Fields

Field	Description
`image`	PA-view chest X-ray image
`findings`	Detailed descriptive narrative of anatomical/pathological observations (Vietnamese)
`impressions`	Clinical diagnostic conclusions (Vietnamese)
`Ages`	Patient age in years
`sex`	Patient gender
`view`	Imaging perspective (PA — Posterior Anterior)
`Ghi chú`	Procedure description (Vietnamese)
`Kỹ thuật`	Technical details of the radiograph

Report Text Length (tokens)

Split	Findings (avg)	Impressions (avg)
Train	46	12
Val	45	14
Test	46	13

Average patient age: ~69–70 years across all splits.

Common Findings

Most frequently mentioned anatomical structures: Heart (tim), Lungs (phổi), Ribs (xương sườn), Diaphragm (vòm hoành), Pulmonary hilum (rốn phổi)

Most common diagnoses: Interstitial lung disease, Cardiomegaly, Pulmonary infiltrates/consolidations, Rib fractures, Aortic calcifications

Intended Use

—Training and fine-tuning vision-language models for Vietnamese medical image analysis
—Benchmarking multilingual and Vietnamese-specific VLMs
—Research on hallucination reduction in clinical AI
—Multi-turn clinical diagnostic conversation modeling

Benchmark Results

Five open-source VLMs were fine-tuned and evaluated on three stages: findings generation → impression generation → multi-turn clinical dialogue. Best performing model: Qwen2.5-VL-7B (ROUGE-1: 84.30% on findings, 95.20% on multi-turn impressions).
