Text Over Image: Auditing Multimodal Robustness in Synthetic Medical Image Detection

arXiv:2606.25375v2 Announce Type: replace-cross Abstract: With the rapid adoption of generative AI, synthetic medical images pose growing risks, including diagnostic deception and insurance fraud. Although prior work has explored vision-language model (VLM)-based synthetic image detection, these evaluations typically consider images in isolation. In clinical practice, however, images are interpreted alongside structured records and metadata, and VLMs are increasingly deployed under joint image-record inputs. We uncover a previously underexamined multimodal vulnerability: when given both modali

Why this matters
Why now

The rapid adoption of generative AI and its application in medical imaging is creating new vulnerabilities that require immediate attention as these systems are deployed in real-world clinical settings.

Why it’s important

This research identifies a critical multimodal vulnerability in AI systems used for medical image detection, highlighting risks for diagnostic integrity and potential for fraud that could undermine trust in AI-driven healthcare.

What changes

The understanding of AI robustness in medical imaging must now explicitly account for multimodal inputs, moving beyond isolated image analysis to integrated clinical contexts.

Winners
  • · AI robustness researchers
  • · Healthcare cybersecurity firms
  • · Regulatory bodies developing AI guidelines
Losers
  • · Patients relying on potentially compromised AI diagnostics
  • · Generative AI developers neglecting multimodal security
