3D amplified MRI – new technique for detailed brain scanning

02 June 2021

Magnetic resonance imaging (MRI) spots differences in the magnetic properties of human tissues, scanning for disease or injury. Usually the images are static, perhaps missing subtle details of our beating and pulsing organs. Here though, MRI evolves in two ways – by amplifying the pulsing movements of tiny brain structures up to 25 times, researchers capture and assess their patterns more acutely. Then, by scanning the brain from different angles, they can create 3D computer models and videos to reveal flowing currents of blood or cerebrospinal fluid. The new technique, known as 3D amplified MRI, may help to detect the early signs of conditions that disrupt these patterns, such as obstructive brain disorders and aneurysms. In the future, similar techniques may peer inside other organs too, perhaps revealing their hidden rhythms.
