acePerformance evaluation of domain-specific and general-purpose AI models for chest radiograph interpretation: a comparative study
Chest radiography remains the most widely used imaging modality worldwide; however, its interpretation is inherently challenging because of overlapping anatomical structures and subtle findings. Recent advances in multimodal large language models (LLMs) have enabled automated radiology report generation, yet their clinical performance relative to domain-specific medical AI systems remains insufficiently validated. This study aimed to evaluate the performance and clinical applicability of a domain-specific multim…
M4CXR achieved higher report consistency than ChatGPT-4o and cut reporting time from 179.2 seconds unaided to 16.3 seconds assisted when interpreting chest radiographs.
Even the domain-specific M4CXR model was inconsistent with reference findings in 25.2% of chest radiograph cases and did not significantly change RADPEER discrepancy rates versus original interpretation.
Study was retrospective and limited to 500 cases from a single tertiary care center, requiring prospective multi-center validation before clinical adoption.

How to verify without trusting this page
Fetch the canonical text of any version from /api/record/TRV-2026-0312 and hash it yourself — for example shasum -a 256 on the saved canonical field. The result must equal content_hash, and each version’s text ends with prev:followed by the prior version’s hash (version 1 chains to 64 zeros). If a single character of any version had been altered since certification, the chain would not reproduce.
