AI takes on radiologists: 30,000-Patient trial to see who reads brain scans better
NCT ID NCT07167043
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study compares how well AI and radiologists diagnose brain diseases using CT and MRI scans. Over 30,000 patients will be included, and the AI has been trained on more than 100,000 previous scans. The goal is to see if AI can match human experts and whether combining AI with radiologists improves accuracy and speed.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- AI-assisted diagnostic system
- What this could lead to
- If successful, this could show that AI is a reliable tool to help radiologists diagnose brain diseases more accurately and efficiently.
- What could go wrong
- This is a validation study, not a treatment trial. AI may not perform as well in real-world settings, and results may not apply to all hospitals or patient groups.

This study's own entry requirements. Only the study team can say for certain whether you qualify.
Who is studied
All patient exams are of men suspected of harboring brain tumors or the other neurological diseases, with or without neurological symptoms, and without a history of prior brain surgery. Patients underwent brain CT and MRI, and were primarily examined at Beijing Tiantan hospital, between 2012-2026.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * For MRI: patients suspected of harboring brain tumors or detected with brain occupancy at initiating or other institution, who subsequently underwent brain MRI. * For CT: patients with or without neurological symptoms, suspected of harboring ischemic, hemorrhagic, space-occupiing, degenerative brain disease, or traumatic brain injury, who subsequently underwent brain CT. Exclusion Criteria: * Patients who opted-out or did not give permission to reuse clinical data. * Patients with a history of prior brain surgery. * Patients whose brain CT or MRI exhibit severe artifacts (e.g. heavy warping due to air, metal artifacts, heavy motion artifacts), thereby impeding the usage of the data.
