Medical neurotechnology firm BrainScope is highlighting a white paper that suggests its BrainScope One electroencephalography-based technology has the potential to reduce unnecessary head CT scans by one-third in a hospital emergency department setting.
A team led by Dr. Rosanne Naunheim from the Washington University Barnes-Jewish Hospital in St. Louis compared 64 patients referred for head CT scans following the traditional referral pathway with use of the BrainScope One referral guideline. The researchers found that using the BrainScope One device could have led to a 33% reduction in head CT scanning in this patient group without any false-negative cases.













![Axial images from unenhanced calcium score cardiac CT (left) and curved planar reformation images from CT angiography (right) show that higher long-term exposure to air pollution is associated with greater coronary artery calcium and more obstructive coronary artery disease (CAD). Top row: Images in a 68-year-old male patient with higher 10-year mean ambient air pollution exposure (7.9 μg/m3 for particulate matter measuring ≤2.5 μm in diameter [PM2.5] and 17.4 parts per billion [ppb] for NO2) with extensive CAD (coronary artery calcium score [CACS] >1,000 and obstructive CAD [≥70% diameter stenosis]). Bottom row: Images in a 57-year-old female patient with lower 10-year mean ambient air pollution exposure (6.3 μg/m3 for PM2.5 and 4.6 ppb for NO2) with no CAD (CACS = 0 and no obstructive stenosis).](https://img.auntminnie.com/mindful/smg/workspaces/default/uploads/2026/06/hanneman.r6SMLzkezo.png?auto=format%2Ccompress&fit=crop&h=112&q=70&w=112)
