British service personnel will soon undergo mobile battlefield brain scans after exposure to explosions, as part of a major medical breakthrough aimed at understanding the long-term effects of blasts on soldiers’ brains.
The world’s first mobile magnetoencephalography (MEG) scanner is being developed by UK scientists to monitor brain activity within minutes of blast exposure, whether in training or combat. The portable system will allow clinicians to assess the subtle, immediate impact of explosions, which may appear transient but can cause long-term health issues.
Blast Exposure and Brain Injury
Thousands of troops may suffer mild Traumatic Brain Injury (mTBI) from repeated exposure to blast waves, including from the British military’s own weapons. Until now, researchers lacked the ability to observe real-time brain activity on-site.
Lt Col James Mitchell, Consultant Neurologist and Chief Investigator of the UK Military Blast Study, explained:
“Twenty years ago, during the early Iraq and Afghanistan campaigns, we primarily saw concussion and mTBI from impact or substantial blasts. Over the last five to ten years, we are recognising the significant role of ‘low-level blast’ — exposure to overpressure from our own weapon systems.”
The MoD has confirmed that repeated exposure can cause long-lasting neurological conditions, making early, mobile assessment essential.
Mobile Technology Comes to the Frontline
The scanner, costing £3.1 million, will be fully transportable and non-invasive, enabling deployment directly to firing ranges, field hospitals, and rehabilitation centres. The system will be available to all three branches of the UK Armed Forces, with the first units expected by March 2026.
Developed by Cerca Magnetics, in collaboration with the Universities of Nottingham and Birmingham, the scanner will not only benefit defence research but also advance studies into sports concussion, dementia, and epilepsy.
Lt Col Mitchell added:
“For the first time, we will build a time-stamped, accurate picture of what happens to the brain in the minutes and hours after blast exposure, and track recovery over time. This will be transformative for the protection and care of our personnel.”
Professor Matthew Brookes, of the University of Nottingham and chairman of Cerca Magnetics, highlighted the wider applications:
“This new generation of MEG lifts limitations that historically confined scanners to universities. Mobile systems can now be taken directly to those who need them most, whether in hospitals or on sports fields. This is likely to revolutionise other areas of neuroscience research.”
Government Support and Wider Impact
Minister for Veterans and People, Louise Sandher-Jones MP, said:
“The safety of our personnel is a top priority. Thanks to technologies like this, even subtle physical changes are now detectable, giving us vital insights to improve decision-making and protect our forces. This funding also benefits wider society, including those affected by dementia, epilepsy, and concussion.”
The mobile brain scanner represents a significant step forward in military medical research, potentially shaping both the future of battlefield care and the broader understanding of neurological health.
