Child's Brain: Images of Unprecedented Precision Obtained by French Researchers

By Enola Tissandie THE Subscribers

French researchers have unveiled the first images of the brains of 6-year-old children obtained using a 7 Tesla MRI. This precision opens up new avenues for research into neurodevelopmental disorders and childhood brain diseases.

Pediatric MRI at 7 teslas

The 7 Tesla MRI is 3.5 times more powerful than standard clinical devices, whose magnetic field oscillates between 1.5 and 3T.

In 2024, the Neurospin nuclear magnetic resonance brain imaging center of the French Atomic Energy Commission (CEA) unveiled the first brain images obtained with Iseult, his MRI at 11.7 teslas, the most powerful in the world for human imaging. Enough to reveal the brain with unprecedented precision, and improve our understanding of certain neurodegenerative diseases.

Fundamental advances that only concern adults. “Going to the child requires an extra effort”, explains David Germanaud, a pediatric neurologist at the Robert Debré Institute for the Child's Brain and a researcher at the CEA Neurospin. He and his team decided to take on this challenge by adapting the use of 7T (Tesla) MRI to the developing brain. In spring 2025, the first brain images were obtained on six children aged 6 to 12, a first in France.
