Researchers magnify the brain in motion with every heartbeat

Now, researchers from Stevens Institute of Technology, in collaboration with University of Auckland and Stanford University, have developed an imaging technique that captures and magnifies the brain in motion, in real time, every time the heart beats, providing a promising and long-awaited diagnostic tool for catching difficult-to-spot conditions such as concussions and aneurysms -- before they become life threatening.

The resulting video images, reconstructed slice by slice, retain the spatial characteristics of an MRI -- the skull and all anatomical features are displayed at actual scale -- while magnifying pulse-driven motion significantly as they animate.

'You can actually capture the whole head 'nodding' in the scanner due to the force of the blood pumping into the brain every time the heart beats,' says Holdsworth, a medical physicist who is now at the University of Auckland and co-lead senior author.

Kurt and Holdsworth, along with Terem, found phase-based amplified MRI to produce fewer errors and give better visibility than the original method, particularly areas of the brain that move most, such as the mid-brain and spinal cord, which helps relay sensory information to the brain.
