Robot vs. doctor: new trial pits machine against human for brain scans
NCT ID NCT07182188
First seen Jun 25, 2026 · Last updated Sep 04, 2026 · Updated 2 times
Summary
This study compares a robotic system to traditional manual methods for performing cerebral angiography, a procedure that images blood vessels in the brain. Researchers will enroll 450 patients aged 18-75 with suspected head or neck vascular issues. The goal is to see if the robot-assisted approach improves success rates, reduces complications, and shortens procedure time.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Vascular Interventional Robotic System (a device that helps doctors perform brain angiography)
- What this could lead to
- If successful, this robotic system could make brain angiography safer and more precise, reducing radiation exposure and complications for patients.
- What could go wrong
- This is a post-market study, so the device is already approved, but it may not show significant benefits over manual procedures. Risks include vascular injury, neurological complications, or system malfunctions.

Inclusion Criteria: 1. Age between 18 and 75 years; 2. Suspected vascular lesions in the head and neck, or other conditions involving head and neck vessels requiring whole-brain angiography for definitive diagnosis or to aid treatment decisions. Including but not limited to: intracranial aneurysms, arteriovenous malformations, cavernous malformations, arteriovenous fistulas, Moyamoya disease, Moyamoya syndrome, subarachnoid hemorrhage, symptomatic intracranial artery stenosis/occlusion, stenosis/occlusion of the carotid/subclavian/vertebral arteries, acute/ chronic subdural hematoma, etc; 3. American Society of Anesthesiologists (ASA) physical status classification I-III (no severe cardiopulmonary dysfunction); 4. Patients who voluntarily participate in this study and sign an informed consent form. Exclusion Criteria: 1. Patients who are to undergo surgery at the same time as cerebral angiography; 2. Renal dysfunction (serum creatinine \> 133 μmol/L or estimated glomerular filtration rate \< 60 mL/min/1.73 m²); 3. Patients with known allergy to iodinated contrast media; 4. Coagulation disorders (prothrombin time \>16s, activated partial thromboplastin time \>45s, or platelet count \<100×10⁹/L); 5. Severe infection, skin ulceration, or vascular anatomical abnormalities at the puncture site (e.g., bilateral femoral artery occlusion); 6. Pregnant or lactating women; 7. Patients with severe cognitive impairment; 8. Patients with psychiatric disorders; 9. Patients unable to undergo head magnetic resonance imaging (MRI), e.g., those with metallic implants, claustrophobia, or other contraindications; 10. Patients with other severe advanced or terminal illnesses; 11. Patients currently participating in other clinical trials.
