Your Medical Scans Could Be an AI Privacy Risk — Here’s What to Know

Your Medical Scans Could Be an AI Privacy Risk — Here’s What to Know

Artificial intelligence is transforming medical imaging, helping radiologists detect tumors, fractures, and other conditions faster than ever. But the same technology that improves diagnoses also creates new openings for privacy violations. Recent reports from the Radiological Society of North America (RSNA) highlight a range of risks that patients and healthcare consumers should be aware of—including the ability to create convincing fake X-rays and the insecure handling of sensitive imaging data.

What Happened

At the RSNA 2025 conference, industry experts noted that AI in radiology is proliferating rapidly. Technical exhibits featured the largest showcase of AI tools for imaging to date. But alongside the excitement, researchers and privacy advocates raised concerns. A key finding: deepfake X-rays can now fool both human radiologists and AI systems. These synthetic images are realistic enough to introduce false findings into patient records or to be used maliciously—for example, to fabricate evidence or to extract insurance payouts.

The RSNA also flagged that many medical imaging AI systems operate on data that is not adequately protected. Patient scans are often transferred to cloud platforms for analysis, sometimes without clear consent or encryption. While no single large-scale breach has been reported specifically linked to imaging AI, the underlying vulnerabilities are well documented. The combination of high-resolution medical images (rich with identifying features like facial structure from CT scans) and AI’s ability to re-identify anonymized data makes this a growing concern.

Why It Matters

Medical images contain far more than the diagnostic information they’re taken for. A simple chest X-ray can reveal body habitus, tattoos, or even implanted devices that are unique to a patient. When these images are fed into AI models—sometimes stored on third-party servers or used for research—there is a risk that the data could be re-identified or misused. Unlike a credit card number, you cannot change your bone structure or the shape of your lungs.

Moreover, the threat of deepfake X-rays introduces a new angle: even if your images are secure, someone could generate a fake scan in your name. For patients, this could mean incorrect treatments, false insurance claims, or difficulty correcting health records. For healthcare systems, the erosion of trust in imaging data is a serious problem.

The pace of AI adoption in radiology is not matched by equivalent protections. Many hospitals and clinics lack clear policies on how imaging data is used when AI tools are involved. Patients often sign blanket consent forms without understanding that their images may leave the facility’s network or be used to train commercial algorithms.

What Readers Can Do

You don’t need to be a cybersecurity expert to take practical steps. Start by asking your healthcare provider straightforward questions before any imaging procedure:

• Where will my images be stored and processed? Ask if the imaging data stays within the hospital’s secure network or if it is sent to an external cloud service or AI vendor.
• What data protection measures are in place? Look for responses about encryption (both in transit and at rest) and anonymization. Note that anonymization is not foolproof—insist on knowing if they strip metadata and remove facial features from 3D scans.
• Who has access to my images? Inquire whether images are used for research or AI training. You have the right to opt out of secondary uses in many jurisdictions.
• Can I see the consent form in advance? Request a copy of the consent form before your appointment. If it includes broad language about data sharing without clear limits, ask for clarification or modification.

Beyond individual action, advocating for stronger institutional and regulatory protections is important. Support policies that require transparency about AI in healthcare. Federal agencies like the FDA are beginning to address software as a medical device, but privacy rules specific to imaging AI remain fragmented. Consumers can push for legislation that mandates breach notifications for health image data—similar to existing rules for electronic health records.
