Medical Imaging AI Raises New Privacy Concerns: What You Should Know

Artificial intelligence is now regularly used to analyze X-rays, MRIs, and CT scans. The technology can help radiologists detect tumors, fractures, and other abnormalities faster and sometimes more accurately than the human eye alone. But as AI becomes more embedded in medical imaging, a less discussed side effect is emerging: new and often poorly understood privacy risks for patients.

A recent article from the Radiological Society of North America (RSNA) highlights what it calls a “Pandora’s box” of privacy-related concerns tied to medical imaging AI. While the piece is aimed at radiologists and hospital administrators, the risks it describes matter directly to anyone who has ever had an MRI or a chest X-ray.

What happened

The RSNA article outlines several ways that AI-driven analysis of medical images can expose patient data in ways that traditional record keeping does not. Among the key concerns:

  • Data breaches involving large image datasets. AI systems require vast amounts of training data. Hospitals and imaging centers often share de-identified images with AI developers or cloud platforms. Even when names and dates are stripped, research has shown that face images reconstructed from CT scans or metadata embedded in DICOM files can be used to re-identify individuals.

  • Third-party access without clear consent. Many AI tools are hosted on cloud servers owned by companies not directly bound by health privacy laws in the same way as hospitals. Patients are rarely told that their images may be sent to an external service for analysis, let alone asked for permission.

  • Lack of transparency about how images are used after the fact. Some AI systems continue to learn from new data after deployment. That means an image taken for one purpose (say, a lung nodule screening) could later be used to train a model for a completely different condition, possibly without the patient’s knowledge.

The RSNA piece does not claim these risks are universal, but it argues that the current pace of AI adoption has outpaced privacy protections.

Why it matters

Medical images are not anonymous in practice, even if they are labeled “de-identified.” Faces can be reconstructed from head CTs. Body shapes and implants can be matched to individuals. And once an image leaves the hospital network, patients lose control over where it goes.

Current regulations offer limited help. HIPAA in the United States covers health providers and their vendors, but it was written before cloud-based AI became common. Enforcement is reactive, not preventive. The GDPR in Europe provides stronger protections, but its application to medical image processing by non-EU companies remains murky.

For patients, the practical consequence is that a routine imaging study could lead to your scan being used in ways you never agreed to—and possibly exposed in a data breach. In 2024, for example, a major health AI vendor suffered a breach that leaked millions of medical images. These incidents are likely to become more frequent as imaging volumes grow.

What you can do

You do not need to refuse necessary imaging to protect your privacy. But you can take a few concrete steps to reduce risk.

Ask your doctor or imaging center about AI. Before a scan, ask whether AI will be used to analyze the image and whether the images will be shared with any third party. If the answer is vague or the staff seems unsure, you can request more details or seek a facility that has clearly posted policies.

Request the facility’s data handling policy. Many hospitals publish a “Notice of Privacy Practices” under HIPAA. Ask specifically about how images are stored, who has access, and whether they are used for AI training. If you receive a form to sign, read it. Opt out of data sharing for research or development if that option is offered.

Look for images stored on cloud platforms. If your provider uses a cloud-based picture archiving and communication system (PACS), ask whether that system uses your images for anything beyond storage. Some cloud providers do, and patients are usually not told.

Consider wearing a face covering during head scans. This sounds odd, but some privacy researchers recommend it. If you are having a head CT or MRI, you can ask if a cloth mask or eye covering is acceptable (without interfering with the scan). It makes facial reconstruction harder to link to your identity.

Protect your patient portal login credentials. Many breaches of imaging data start with compromised patient portal accounts. Use a unique password and two-factor authentication if available.

Finally, exercise your right to request a copy of your images. Under HIPAA, you are entitled to receive your own medical images. Having a copy does not give you control over how the original is used, but it helps you track where your data has been.
